Little Mix joined Outkast onstage at Wireless festival on Sunday (06.07.14).
'Salute' hitmakers Jade Thirlwall and Leigh-Anne Pinnock were invited onto the stage by Andre 3000 and Big Boi to dance with them as they performed their 2003 smash hit single, 'Hey Ya'.
The hip-hop duo - who reunited at the Coachella Festival in April - marked their first performance in the UK in several years with a slew of old favourites including 'Ms. Jackson' and 'Roses', which had the crowd singing along.
Sunday headliner Bruno Mars, meanwhile, put on an electric show that earned high praise from fans in attendance - including A-list actor Hugh Jackman - and his incredible stage show, complete with fireworks, marked a stark contrast to the controversial performances by Kanye West on the previous two nights.
The 36-year-old rapper was booed for deviating from his music into long rants on both Friday (04.07.14) and Saturday night (05.07.14), but Bruno, 28, kept the 100,000-plus crowd on side by not only performing his own hits, but interspersing his set with classics such as Led Zeppelin's 'Whole Lotta Love', Michael Jackson's 'Rock With You' and Ginuwine's 'Pony'.
Bruno, who alluded to his humble beginnings performing in London clubs, regaled the crowd with hits including 'Just the Way You Are', 'Treasure' and 'Grenade' before closing the show with 'Locked Out of Heaven' and 'Gorilla'.
British pop star Ellie Goulding also took to the main stage at Finsbury Park, London, performing 'Burn' and 'Goodness Gracious' for a crowd that included her pal Cara Delevingne and The Saturdays members Frankie Sandford and Vanessa White. Following her early evening set, Ellie and supermodel Cara jetted across town to Hyde Park to watch her boyfriend Dougie Poynter perform with McBusted a the Barclaycard British Summer Time event.
Robin Thicke headlined the Pepsi Max stage, which was also commandeered by Sean Paul and Clean Bandit.
The Boombox Stage, meanwhile, was headlined by 'La La La' hitmaker Naughty Boy.
Other celebrities who attended the third day of Wireless included Little Mix's Jesy Nelson, Frankie Sandford's soccer star fiancé Wayne Bridge, 'The Only Way is Essex' star Lauren Pope and actress Louisa Lytton.

Michael Hutchence's half-sister has begged his daughter to Visit Australia.
Tina Hutchence has penned an open letter to 17-year-old Tiger Lily Geldof - who is raised by her late mother Paula Yates' ex-husband Bob Geldof - urging her to visit her late father's home country because the late INXS rocker was "desperate" for the youngster to know her heritage.
In the note, which was published in New Idea magazine, Tina wrote: "I know Michael would want you to visit Australia, the country he loved so much.
"He made certain you had an Australian passport, and he desperately wanted you to spend your formative years here."
In the note, Tina goes on to recall how much her brother - who was found hanged in a Sydney hotel aged 37 in 1997 - doted on his daughter, who was just 16 months old when he died.
She wrote: "You don't remember how he held you to his chest and sang in a voice so sweet and gentle until you closed your eyes and drifted off; but I do."
Since Tiger Lily's mother died in 2000, it is believed she has made just one visit to Australia, when she spent five days with her grandmother Patricia Glassop in 2006.
However, when her elderly relative passed away in 2010, she did not return for her funeral out of fear of the media attention it would attract.
Michael's former bandmate Tim Farriss previously admitted his late friend would have "hated" the thought of his daughter being raised by Bob, who formally adopted her in 2007.
He said: "Michael hated Bob in the end so much, to think that he would end up as the sole parent of Tiger Lily would have been the most horrific thing he could have imagined. But luckily for Tiger she had Bob at the end."

Katy Perry's merchandise company are suing counterfeitters.
Bravado International - which licenses the exclusive rights to sell t-shirt, hats, posters and other products from a variety of artists, including the Red Hot Chili Peppers, Rolling Stones and Led Zeppelin - have filed court documents against fraudsters who sell illegal merchandise outside the 'Roar' hitmaker's concert in a bid to get them to stop.
According to website TMZ, the company have asked a judge to call a halt to the counterfeit sales and confiscate any unofficial merchandise sold near her shows.
This isn't the first time Bravado International have attempted to stop fraudsters selling fake merchandise.
In 2009, they filed a lawsuit against Dollar Days International, arguing they were illegally using the names and likenesses of stars including Michael Jackson and Jim Morrison in the sale of products including watches, shirts and play money.
In that case, the company sought $2 million for each violation of their rights.
Katy is currently involved in another legal battle as she is being sued by Christian hip-hop star Flame - real name Marcus T. Gray - and three other musicians who have accused her of ripping off their award-winning Christian gospel track 'Joyful Noise' for her hit song 'Dark Horse.'
The 32-year-old rapper claims in court documents that 29-year-old Katy, whose parents are pastors, hijacked their music, tarnished it with black magic, witchcraft and paganism, and ruined their reputation in the Christian music world because of the imagery that appears in her music video.
The group, who released their track five years ago, are seeking unspecified damages and want the 'I Kissed a Girl' singer, who is currently on her 'Prismatic World Tour' to be banned from using any form of their music immediately.
The star co-wrote the track with singer-songwriter Sarah Hudson in her native Santa Barbara, California, and previously claimed it was inspired by the 1996 film 'The Craft' for the song, which is "about warning a guy that if you're going to fall in love with me, make sure you're sure because if not, it's gonna be your last."

Pierce Brosnan credits "faith" for helping him overcome tragedy.
The 61-year-old actor was left devastated when his first wife Cassandra Harris died from ovarian cancer in 1991 and his adopted daughter Charlotte succumbed to the same disease last year, and thinks his religious beliefs and upbringing have given him the strength he needed to carry on.
Asked how he gets through his dark days, he said: "I would say faith, being Irish, being Catholic, it's ingrained in my DNA."
The 'Long Way Down' actor - who is now married to Keely Shaye Smith - also admitted to being a keen artist.
He told the New York Daily News newspaper's Confidenti@l column: "I paint landscapes, figuratives. I painted all my life. In fact, I started as a commercial artist."
The former James Bond star criticised the lack of choice in movies, and think TV has grown into a much more exciting medium.
He said: "TV is such a provocative, stimulating ground right now. Movies are somewhat diminished by blockbusters, which are great, but there's not enough choice."
Pierce has previously spoken of how his faith has been "good" to him during tough times.
He said: "It always helps to have a bit of prayer in your back pocket. At the end of the day, you have to have something and for me that is God, Jesus, my Catholic upbringing, my faith... God has been good to me. My faith has been good to me in the moments of deepest suffering, doubt and fear. It is a constant, the language of prayer."

Ellie Goulding finds long-distance love tough.
The 'Burn' singer finds it difficult travelling up north to Manchester from London to visit her boyfriend, McBusted musician Dougie Poynter, but thinks it's definitely worth the effort.
She told Britain's GLAMOUR magazine: "Long distance isn't easy at all. You have to work at it, like anything in life. But I'm very happy. I'm happy, man! I'm chilled."
Ellie, 27, also laughed off claims she was romantically involved with Sam Karl, the US personal trainer she was pictured on a yacht "date" with earlier this year, but has learned speculation about her personal life is a "downside" of her career success.
She laughed: "He's a friend of a friend and we were actually this far away [throws arms wide apart]. It's all about angles, this is how photographers do it. It's very wrong.
"Very naughty... but I've come to accept there will always be something to say. Luckily I've got to a point where nothing can obscure the fact I'm a successful artist.
"I've done well and people still really love my music. And I'm always about the music. My friends know that and the only downside is people reading things like that and assuming I'm something that I'm not. But that happens. And it will always happen."

Amanda Barrie will play a psychic in the new series of 'Benidorm'.
The former 'Coronation Street' actress - who played cafe boss Alma Baldwin for more than 15 years - is set to join the comedy as Psychic Sue, in a role which will reunite her with former soap co-star Sherrie Hewson.
A source told the Daily Star newspaper: "It's a thrill to have Amanda back on the box. She and Sherrie are a hoot together."
Amanda's character will be seen regularly at the Spanish resort's Blow and Go hair salon, and it is said she will end up in a storyline with Kenneth du Beke, played by Tony Maudsley, and Adam Gillen's character Liam Conroy.
The 78-year-old star is making her TV return, with most fans remembering her 'Corrie' character getting cancer and being killed off in 2001.
Two years after leaving the soap, she appeared in 'Bad Girls' and was also seen as a contestant on Gordon Ramsay's 'Hell's Kitchen' in 2004.
Meanwhile, the next series - due in 2015 - will see Joan Collins back as hotel group boss Crystal Hennessy-Vass, plus guest appearances from Nadia Sawalha and John Challis.

Sharon Osbourne has warned serious singers not to sign up for 'The X Factor'.
The showbiz matriarch, who quit the judging panel after one series last year, has revealed she doesn't see the point in artists who write their own material signing up for the ITV singing competition because it will compromise their vision and ruin their credibility.
She admitted during a Q&A session with show host Dermot O'Leary: "Always my mentality when I was on 'X Factor' was, if you were a singer-songwriter you have a definition of who you are, writing songs you love and that suit your voice and who you are.
"For me, if you were a singer-songwriter, do not go on a talent show. It's not going to work. Could you imagine them doing ABBA week, or '80s week? It's just not for you - because you know who you are.
"Talent shows are fantastic and they change people's lives. But they are not for people who are singer-songwriters. It's not the thing to do."
Sharon - whose departure paved the way for Cheryl Cole and Mel B to join show stalwart Louis Walsh on the judging panel, as well as returning head judge Simon Cowell - also confessed the "fleeting" fame 'The X Factor' provides rarely lasts more than a year.
She added: "When you look at the long-term of talent shows, there are very few people who actually sustain any fame. It's fleeting, fleeting, fleeting. People forget who was on last year.
"It's all about the year that they're watching. There have been some superstars, but the majority are forgotten."

Stephanie Pratt has signed up for 'Celebrity Big Brother'.
The outspoken American could follow in the footsteps of her brother Spencer Pratt and his wife Heidi Montag - who appeared on the show in January 2013 - by entering the famous reality TV house in August and producers are hoping she'll be just as controversial as her sibling and his spouse.
A source told The Sun newspaper: "She is sexy but also knows how to be controversial.
"Despite being American she has enough experience of British TV to know just what producers are after.
"And it gives bosses the perfect excuse to bring Spencer and Heidi back over to support her."
Stephanie rose to fame along with Spencer and Heidi on MTV reality show 'The Hills' and she has now become a staple on 'Made in Chelsea' after dating lothario star Spencer Matthews.
'CBB' bosses will be hoping the blonde starlet opens up about her troubled past which includes a conviction for drink-driving.
Stephanie is just the latest name linked to the new series of 'CBB', following rumours Hollywood actor Gary Busey and 'Gogglebox' star George Gilbey could appear on the Channel 5 reality show.
Katie Price's cheating husband Kieran Hayler has reportedly turned down a £200,000 offer to enter the house.

Dean Fagan won't watch his steamy 'Coronation Street' kisses.
The actor's alter-ego Luke Britton is set to lock lips with a drunken Carla Barlow (Alison King) in tonight's (07.07.14) episode of the ITV soap, but Dean admits he won't be tuning in because he doesn't want to upset his girlfriend, Louise Pridding.
He told The Sun newspaper: "My girlfriend ridicules me about playing a ladies' man. Of course I'm not like that in real life but it's still going to be weird seeing your partner chatting up other girls and I'd never force her to watch me doing a kissing scene.
"We don't watch 'Coronation Street' together for that reason. If it's just pure dialogue I would ask what she thought -- she's my biggest critic and I really appreciate her opinion.
"But we'll most likely give the scenes with Carla a miss!"
Dean - who took on the role of mechanic Luke six months ago - also receives plenty of feedback from his father Lee, who is a real-life mechanic.
He added: "He lets me know if I'm doing something wrong!"
The hunky actor's 'Corrie' contract was recently extended and he admits it's a "privilege" to appear on the soap.
He said: "It's a privilege and a pressure to get it right, but it's a fantastic feeling and I'm very grateful to the show for letting me be on it."

Bruce Dickinson says Iron Maiden would consider opening an interactive museum.
The legendary rocker insisted the group wouldn't want to put their memorabilia behind a glass cabinet where fans aren't able to interact with the history of the band, and joked their mascot Eddie isn't "that sensitive".
He told the Daily Star newspaper: "We've got loads of gear kicking around. I don't want it to end up in some po-faced museum, with people in white suits saying 'Don't touch this'.
"I donated a jacket to the Rock 'n' Roll Hall Of Fame and it was locked away in a glass cabinet miles away from your eyes. Eddie's not that sensitive."
Meanwhile, he blasted London, UK for its rules surrounding live events and insisted the band would rather play festivals like Download and Sonisphere than have to agree to certain limits at Hyde Park.
He said: "Knebworth and Donnington are great. They let you make a racket which is all the fans want to hear.
"We considered playing Hyde Park again. The thought of filling central London with Iron Maiden fans is brilliant.
"However, the noise restrictions at Hyde Park are so silly. If somebody has a loud conversation you have to shush them."
The band's fellow heavy rockers Black Sabbath played at the outdoor venue on Friday (04.07.14), and while Bruce admitted it was their choice, Iron Maiden wouldn't have taken the "tame" option.
He said: "Sabbath made their decision, but we looked at it and thought it's too tame."

McBusted arrived on stage in a Delorean 'time machine' on Sunday night (06.07.14).
The super-group - comprising McFly members Tom Fletcher, Danny Jones, Dougie Poynter and Harry Judd, and Busted's Matt Willis and James Bourne - were lowered onto the stage at London's Hyde Park in the vehicle, made famous as the time travel device in the 'Back to the Future' movies following a video montage looking back on Busted's career highlights, before the six-piece launched straight into 'Air Hostess'.
Despite the heavy rain, the crowd's spirits couldn't be dampened as they danced and sang along to both group's most famous hits, including 'You Said No', Five Colours in her Hair' - during which a rainbow appeared over the stage as the weather began to clear - and 'Obviously'.
Midway through the set, the group headed to a second, UFO-shaped stage in the middle of the Barclaycard British Summertime crowd to perform several tracks, before returning to the main stage to end the performance.
The group left the stage after 'What I Go To School For' - which was performed to a backdrop of saucy doodles and cartoons on the big screen - and an excerpt of Tom's infamous wedding song was played, but the video was edited to have James and Matt crash the speech and they then all returned to perform 'Crashed the Wedding', all donning wedding dresses, apart from drummer Harry who was topless except for a bowtie.
Dougie then discovered he couldn't get his dress off so decided to finish the set in the gown, and after declaring they wanted to play the whole gig again, the group launched back into 'Air Hostess' for a second time.
They closed their set with 'All About You' and 'Year 3000'.
Earlier in the day, James had joined Backstreet Boys - who had hailed him as their "biggest fan" - to sing 'I Want it That Way' towards the end of their hit-laden set.
Other performers included The Vamps and Diversity, while performances from Lawson and Five were cancelled due to continuing technical difficulties in the Barclaycard Theatre.

Mel Gibson thinks the film industry is becoming more "difficult".
The actor has a stake in production company Icon Productions, but hasn't been investing in as many projects recently because it's not always "cost effective" to make great independent movies.
Speaking at the Karlovy Vary Intl. Film Festival, he told Variety.com: "I've still got Icon, and if I see something that is really cool and worthwhile doing, and cost effective... Like the other independents, I'm not in there to get burned. But it's becoming more difficult, put it that way, for everybody."
Gibson lamented the major fact studios are putting all their money into blockbusters and shunning independent movies, comparing the process of trying to get an indie film green-lit to being "raped and beaten".
He said: "It's just the way things are. There's been a big shift in the way things used to be. I mean, there aren't as many films being done at the studios, and they tend to gravitate toward the big blockbustery things with pyrotechnics and stuff like that, which is valid. They are entertaining.
"I think stories of more substance are not as sought-after or fostered as much. And of course those things are left largely to the independent filmmakers. For the independent filmmakers, traditionally, it's been more difficult to get distribution, and to get back what you put in. It's just more difficult. And there are a lot of gatekeepers along the way.
"It's like anything. There are a lot more hurdles to overcome. You are going to get robbed and raped and beaten. It's just part of the game. There are a lot of sharks in the water."
Mel picked up the Crystal Globe for outstanding artistic contribution to world cinema at the film festival on Friday (04.07.14).
