Prince is reportedly in talks to play a surprise set at Glastonbury festival this week.
The 'Raspberry Beret' hitmaker, who was rumoured to be headlining the event at Worthy Farm, was ruled out after Metallica, Kasabian and Arcade Fire were announced but sources claim he still wants to surprise festival-goers at the event in Somerset.
A source told The Sun newspaper: "Prince wants to show up somewhere as a surprise. He has spent so much time in the UK lately, he'd love to do an impromptu set."
Organiser Michael Eavis and daughter Emily previously said Prince would not be playing the festival this year but they still hope to book him in the future.
The 56-year-old musician, who was bookies' favourite the headline, has been touring the country for the past couple of months with his all-girl female rock band 3RDEYEGIRL.
Meanwhile, Metallica were reportedly in talks to cover a track by the 'Purple Rain' singer but frontman James Hetfield was against the idea.
The source added: "There was the suggestion of them covering Prince, reminiscent of when Jay Z came on to Wonderwall [by Oasis], but it got a firm, 'No', mostly from singer James Hetfield."
EE has installed a bespoke 4G network and card readers for contactless payments at the event this year and the 'Highspeed Herd' will bring festival-goers superfast WiFi. The cows were painted by legendary bin painter, Hank, who has decorated thousands of colourful bins for the festival since the '80s.

Britain's Prince William received a helicopter for his 32nd birthday.
The lucky royal was presented with the ultimate birthday gift from his grandmother Queen Elizabeth yesterday (22.06.14), according to the Daily Mirror newspaper.
William is now the proud joint owner of six-year-old Agusta A109S Grand, which has already been dubbed 'Heirforce One' after the US President's aircraft, and can fly at speeds up to 180mph.
The helicopter will come in handy to whisk the prince and his wife Duchess Catherine off to their royal engagements quickly, so they can make the most of their time at home with their 11-month-old son, Prince George.
The £8 million chopper boasts custom leather seats, carries up to seven people and will be made available for other members of the royal family to use.
It is not known whether the Duke of Cambridge, who is an RAF helicopter pilot, will be manning the aircraft himself.
He began his military training in 2009 at RAF Valley in Anglesey, Wales, but renounced his position with the Search and Rescue Force last year to focus on his family and his royal engagements.

Ellen DeGeneres, 'The Young and the Restless' and Steve Harvey were among the winners at the Daytime Emmy Awards yesterday (22.06.14).
The 56-year-old presenter missed the ceremony but scooped the Outstanding Talk Show - Entertainment prize for the fourth time, having previously taken it home in 2010, 2011 and 2013, while the popular soap picked up six prizes, including the coveted Outstanding Drama Series trophy.
Steve won Outstanding Game Show Host for his work on 'Family Feud', and Outstanding Talk Show - Informative for his self-titled show.
However, he wasn't at the ceremony at the Beverly Hilton Hotel in Beverly Hills, which 'Family Feud' executive producer Rushion McDonald revealing he had gone on vacation in Bali as he didn't expect to win.
Elsewhere, Sharon Osbourne caused controversy with an expletive-filled speech when she took to the stage to present an award and urged the audience to lighten up as, for the first time in its history, the ceremony wasn't being televised.
Arriving on stage after 'Entertainment Tonight' executive producer Linda Bell Blue made a lengthy acceptance speech, Sharon said: "Finally, my lord, I feel like I've been her for five f***ing hours and I just got here.
"It's not being televised -- just f***ing get p***ed and have a good time.
"Everyone can throw up in the toilet and go home and f**k everyone they work with."
While the show ended over 10 minutes early, the final winner, 'The Young and the Restless' producer Jill Farren Phelps was unimpressed when host Kathy Griffin ran out midway through her Outstanding Drama Series acceptance speech and cut her short as she spoke of pride in the ownership of the show.
Kathy yelled: "Oh, for Christ's sake with your pride of ownerships. Wrap it up, lady! If you thank your f***ing dog..."
The outspoken presenter had also mocked the fact the show wasn't televised, saying at one point: "It's not even a real show, it's like Twitter, relax."

Katie Couric has got married.
The talk show host tied the knot with John Molner in an intimate ceremony at their home in East Hampton, New York on Saturday (21.06.14) that was attended just by family - including her daughters Ellie, 22, and Carrie, 17, and his children Allie and Henry - and close friends.
Shortly after the ceremony, Katie tweeted: "So excited to make my debut as Mrs. John Molner!"
The 57-year-old presenter wore a Carmen Marc Valvo ivory crystal beaded and embroidered Chantilly lace gown with a halter neck, and John's nieces and nephews were ring bearers and flower girls.
The couple's garden had been decked out especially for the celebration, with centrepieces including garden roses, dahlias, hydrangeas and peonies, while guests were entertained by music from Hank Lane and tucked into a delicious strawberry lemon cake after their meal.
Katie previously revealed she was allowing financier John, 51, arrange their wedding.
She said: "He's the wedding planner!"
The couple got engaged last September after two years of dating and the former 'Today' host previously admitted she was confused when John popped the question.
She said: ''He said that there was a reason he'd brought me there to the beach, and that he loved me and was committed to me, and I said, 'Yeah, I know that, you didn't have to bring me here to tell me that.'
''Finally he said, 'Couric, I'm trying to propose to you,' and I was stunned.''
Explaining how she responded, she laughed: ''It took me a while to say yes, because I was so confused! It took a long time for my brain to process what was going on.''
Katie was previously married to Jay Monahan - the father of her daughters - but she was widowed when he tragically died from colon cancer in 1998 at the age of 42.

Ellie Goulding and Calvin Harris were reportedly "holding hands" during a night out.
The 'Burn' hitmaker, who is dating McBusted bassist Dougie Poynter, has been good friends with the superstar DJ for a number of years but witnesses claim they appeared closer than usual at London's Mahiki nightclub on Saturday (21.06.14) after Capital FM's Summertime Ball at Wembley Stadium.
A source told The Sun newspaper: "Calvin and Ellie have been friends for a while but they appeared more than that this time around.
"They were seen holding hands and hugging at the club and more than a little bit all over one another."
Calvin, 30, and Ellie, 27, have been back in the recording studio recently after their song 'I Need Your Love' became a hit last year and they were filmed kissing in the video for the track.
Ellie uploaded a number of photographs of the pair working on new material on her Instagram account and fans were quick to point out how great they look together.
Meanwhile, Calvin has just split from 'I Will Never Let You Down' hitmaker Rita Ora, who was also seen with a mystery man on Saturday night at London's trendy new nightspot Chiltern Firehouse.
Calvin reportedly ended his year-long relationship with Rita, 23, by announcing their split on Twitter and the singer was left "embarrassed" by the shock announcement.

Louis Tomlinson is planning to charge fans £250 for a selfie with him.
The One Direction star recently completed his takeover of Doncaster Rovers soccer club and in a bid to raise funds for the team he's offering his fans the chance to have their picture taken with him in return for a £250 pledge.
The 22-year-old heartthrob - along with his business partner, former Doncaster Rovers chairman John Ryan - has launched a campaign on Crowdfunder and has set a £2 million target for the League One side.
The Tomlinson Ryan Trust have donated a six-figure sum to show their commitment and have so far raised £553,617 for the South Yorkshire club by offering soccer and One Direction fans a number of incentives, including photos with Louis and thank-you videos from the star.
Louis - who is a lifelong fan of his hometown soccer club - said: "I want to see the Doncaster Rovers supporters get the club the success it deserves ... This is a big step which I believe will open up opportunities to provide a very, very exciting future for the club and its supporters."
However, fans will be left disappointed if the £2 million sum is not raised as pledge rewards will only be given out if the Trust reach their target.

Kenny Ireland is reportedly battling cancer.
The 'Benidorm' actor, who plays the Solana hotel's resident swinger Donald, has sadly pulled out of the ITV sitcom's upcoming summer series after being diagnosed with the disease and is now focusing on his recovery.
A source told The Sun newspaper: "The diagnosis was crushing for Kenny and his family. This is obviously a very difficult time for them and they are coping as best they can.
"The priority is Kenny's health. As soon as he was given the news he pulled out of the latest series of 'Benidorm' which, of course, everyone understood."
A spokesperson for Kenny declined to comment, but confirmed he wouldn't appear in new episodes of the popular show, which is about to embark on its seventh series.
The Garvey family have also checked out of the programme, with Mick (Steve Pemberton) Janice (Siobhan Finneran), Madge (Sheila Reid), and Michael (Oliver Stokes) receiving a big send off in the new season's opening episodes.
Steve recently explained: "We've left 'Benidorm'. We filmed our scenes early on this year so we're going to be in the first episode or two of the new series, but then the whole Garvey family are leaving."

Example gets abuse about his voice on Twitter.
The 'Kickstarts' hitmaker's upcoming fifth album 'Live Life Living' has cemented his transition from rapping to singing, and despite receiving criticism about his vocal prowess on the social network, the musician feels confident about his ability to convey emotion in his voice.
He told Digital Spy: "I think there's some people who don't like my voice and that's fine and the reason they don't like it is probably because of the sound of it.
"I often get tweets going, 'You can't sing, you're f**king awful' but then I get hundreds of tweets a day saying, 'I love Example's voice - it's so unique and gravelly and has so much emotion in it'. I don't think there's been anyone in history where everybody loves their voice."
Example denied having a course of singing lessons and feels like his music actually benefits from his lack of vocal training.
He explained: "I had one singing lesson and it was mainly to learn how to warm up my voice. I said shall I come back for more lessons and she said, 'Well you've got such a unique sound to your voice I don't think I can teach you to sing'.
"I think if you start to learn to sing in the traditional sense you lose all the character in your voice."
The star is relieved marrying model Erin McNaught helped him give up his party lifestyle because he was becoming a "self-destructive" person.
He reflected: "I mean there were some amazing, fun moments, you know? Like just being able to do whatever you wanted when you wanted, but it was very self-destructive and I didn't really like me as a person.
"I didn't really like who I was and a lot of my friends didn't like me, my ex-girlfriend didn't like me and my family didn't really like me back then in like 2010. I'm in a much better place now."

Ryan Thomas doesn't want any more children.
The 'Coronation Street' star - who has daughter Scarlett, five, with former co-star Tina O'Brien - admits becoming a dad at a young age was tough and he isn't sure he could have another child to look after.
He said: "It's such a big responsibility to be a parent. You have to sort of give up your life for them in a way. Having one's hard but having more ... it's just a lot of responsibility and I'm not sure if I want that again.
"I was just so young. I've always been there for Scarlett, but I'm just not sure I want to go through all that again, although it's getting easier now Scarlett's getting older.
"Then again, if you meet someone you love, you might end up having more children, so who knows."
The 30-year-old hunk is in a relationship with Bollywood actress Amy Jackson, 23, and says he can't wait to go out to India to see her in her element.
Ryan told Britain's OK! magazine: "She's going again in July then her film is out in August, so I'd like to go over with her for that. I know in certain areas she's crazy famous and it would be nice to experience what it's like for her."

Millie Mackintosh says she has a "whole new group of friends" after quitting 'Made in Chelsea'.
The 24-year-old beauty, who left the E4 show last year prior to her wedding to Professor Green, has revealed she doesn't keep in touch with many of her former co-stars, except Rosie Fortescue, and has moved on from the show and made new pals.
She explained: "I'm really missing Rosie while she's been in New York [filming 'Made in Chelsea: New York']. I'm jealous that we didn't get to film out there but I did some amazing trips like Morocco and Cannes.
"I saw Caggie [Dunlop] recently but I've made loads of new friends. You have friends in your teens and then you make a whole new group of friends in your twenties.
"I don't speak to many people in 'Chelsea'. I stay out of it. I don't even watch it!"
Fashion fan Millie is currently competing on the latest series of BBC cooking competition, 'Celebrity MasterChef', and can't believe she's working alongside supermodel Jodie Kidd.
She told Britain's OK! magazine: "I've met some of the other people who'll be on it. Jodie Kidd is a lot of fun and a great cook, and Lesley Ash is lovely. The girls stick together, but there are some dark horses."

Kelsey Grammer wants to reprise his role as Beast in a future 'X-Men' film.
The 59-year-old actor made a brief cameo as the ape-like mutant superhero at the end of the Marvel franchise's most recent instalment, 'X-Men: Days of Future Past', and would jump at the chance to play the part again.
He admitted to Collider.com: "I hope to do another. I hope they find some way to come up with a new story that involves Beast in my timeline."
Grammer, who first appeared as Beast in 'X-Men: The Last Stand', revealed he took the initiative to call director Bryan Singer and asked to make a return because he had such fun filming the 2006 movie.
He said: "Actually I called Bryan. I bumped into Hugh Jackman and he said, 'Oh you're gonna be in another X-Men, mate!' and I said, 'No I'm not, I don't know anything about it.'
"So I made a couple of inquiries, got a hold of the script, found out that it's primarily dealing with the past and that timeline I don't have a place in, but I saw that at the end there was this coda where he made an appearance. I said, 'Listen, I really want to be involved,' so Bryan arranged for it and I had a lovely time."

Lindsay Lohan reportedly ran around Selfridges in the nude.
The 'Mean Girls' actress shocked onlookers at the plush London department store when she allegedly charged out of her dressing room and started racing around the shop in the buff, laughing hysterically all the while.
A source told The Sun newspaper: "Lindsay took some items into the changing room. Halfway through, she ran out of the room with nothing on and was chased by members of staff who were trying to cover her up.
"She was laughing her head off and literally giving staff the run-around as customers looked on."
Lindsay, 27, was due to meet with a personal shopper at Selfridges later that day, but subsequently cancelled her appointment following her bizarre display.
The insider added: "Lindsay was booked in for a personal shopping experience with a posh brand at the shop later that day, but it didn't happen."
The flame-haired beauty is considering a permanent move to London and is being lined up for a role in West End show 'Speed-the-Plow', which will reportedly open in November.
Lindsay, who completed a court-ordered stint in rehab last year, has started house-hunting in the city and feels she has found her spiritual home after enjoying a series of judgement-free nights out in the UK.
A source previously said: "Lindsay's convinced everyone in America is out to get her, but she's had the opposite experience in London.
"She loves British culture and says people have treated her with respect for the first time in years. Now she's looking into the immigration process and planning a full-time relocation."
