Janelle Monáe says paying homage to David Bowie in a new Pepsi MAX advert was "truly a dream".
The R&B singer appears in the commercial as a busker, singing Bowie's famous track 'Heroes' for small change, and she was thrilled to have been chosen to take part.
She said: "'Heroes' is one of my favourite David Bowie songs, he's just the coolest artist out there, so to be able to cover the song and to pay homage to him is truly a dream."
The advert, part of the brand's Now Is What You Make It campaign, ties in with the World Cup and was filmed in the streets of Rio, where this year's competition will take place.
It also features soccer stars Robin van Persie, David Luiz, Sergio Ramos, Sergio Agüero, Jack Wilshere and Leo Messi, performing impressive tricks with a football.
Janelle, who was nominated for International Female Solo Artist at this year's BRIT Awards, continued: "I love everything the film stands for. To me, it is all about that extraordinary burst of courage and passion which can embolden everyday people in a moment of spontaneity, which is also the message of David Bowie's venerable song.
"I was honoured to join Pepsi for this campaign and remind people that now more than ever, we can all be heroes."

Sam Claflin struggled to keep a "straight face" while filming 'The Quiet Ones'.
The 27-year-old actor - who is best known for his role as Finnick Odair in 'The Hunger Games' - hits the big screen as Brian McNeil in the John Pogue-directed horror and insists it was difficult not to laugh on set where the cast needed to put on "scared faces".
Talking to BANG Showbiz at the film's premiere in London yesterday (01.04.14), he said: "Trying to keep a straight face was so hard. The cast knew each other so well and spent the majority of the filming with our scared faces. We had this amazing director making noises and sound effects, as you can imagine there's no music, no sound effects [while filming], so we were lucky enough to have this amazing man!"
His co-star Jared Harris - whose character Professor Coupland attempts to create a poltergeist - revealed filming was intense because of the short period of time they had to shoot scenes.
He added: "Shooting a movie in three and a half weeks was tough, we were under a lot of pressure. Luckily we had rehearsals before but it's a tough schedule to stick to."
They were joined by Olivia Cooke and Rory Fleck-Byrne on the red carpet.

Brad Pitt is in talks to star in an untitled World War II film.
The 50-year-old actor is negotiating a role in a romantic thriller penned by Steven Knight, which will be produced by Graham King through his GK Films banner.
According to Deadline.com reporter Mike Fleming, "While it's not a done deal yet and not yet set with a distributor, I'm hearing it's serious and that a big director will be set."
Pitt recently wrapped up filming Second World War epic 'Fury' which is set in April 1945 and follows the Allies as they make their final push in Europe.
Pitt plays army sergeant, Wardaddy, who commands a Sherman tank called 'Fury' and its five-man crew on a deadly mission behind enemy lines.
He stars alongside an A-List cast, including Nymphomaniac's Shia LaBeouf, 'Noah' actor Logan Lerman, 'American Hustle' star Michael Pena and The Wolf of Wall Street's Jon Bernthal.
Pitt previously starred in Quentin Tarantino's 'Inglourious Basterds', released in 2009. The film begins in German-occupied France and tells a story of two fictional plots to assassinate Nazi Germany's political leadership.

Britain's Prince Andrew admits we shouldn't "be afraid of failure".
The Duke of York is hosting Pitch @ Palace on Wednesday night (03.04.14) at St James's Palace where 12 budding entrepreneurs will have the chance to put forward their ideas to an audience of business leaders, venture capitalists, investors and other individuals.
This is the second year the event will take place but last year's was done on a smaller scale and the duke insists it's a new idea which may fail.
He explained to the Daily Telegraph newspaper: "I'm looking forward to see what happens. I'm excited.
"This is about getting out there and doing it. To some extent, as a start-up, we are trying to do something that's new and has not been tried before, could potentially fail, and we'll see what comes out of it. It may surprise us all. We may find it's a complete disaster, I don't know, but if you don't try it, you'll never know.
"We are serial entrepreneurs in that we're coming up with these ideas all the time. This is just one of a number."
The 54-year-old royal believes failure is an "experience worth having" before achieving the end goal of "success".
He added: "Don't be afraid of failure. It's quite a good thing to fail. You'll never end the fear of failure, we can only encourage people to recognise that failure on the road to success is an experience worth having."

Kiefer Sutherland's biggest challenge filming '24: Live Another Day' was London's traffic.
The 47-year-old actor reprises his role as CTU (Counter Terrorist Unit) agent Jack Bauer in the next installment of the action series, where he finds himself on the run in England's capital, and he admits he struggled to cope with the amount of road users in the city, insisting Los Angeles is "empty" by comparison.
He told the Daily Star newspaper: "Jack Bauer has been through some pretty dangerous and tricky situations in his time.
"But I don't think he has ever had to deal with anything as bad as London traffic.
"I mean seriously, I forgot how intense it is, it makes the roads in LA look empty."
Kiefer shares a "real connection" with London since he was born in the city before his family moved to California where he lived until him and his mother settled in Toronto where he was schooled.
He added: "I love London and England, though. I was born there and have a real connection with the country. So it is special for the new season to be set there."

Chantelle Houghton says Kelly Brook has "lost her mind" following her whirlwind engagement.
The TV personality insists the busty brunette is "gorgeous" and could do better for herself after David McIntosh - a former royal marine - popped the question last month.
Kelly and David have had an on/off relationship since they met on New Year's Eve (31.01.14) three months ago and although the former 'Gladiators' star spent a large amount of time at Kelly's north London home in the early stages of their romance, they reportedly split up shortly after Valentine's Day (14.02.14).
Chantelle told New magazine: "Has Kelly Brook lost her mind? She's gone from dumping him and erasing all traces of him from her Instagram account to saying he's the most wonderful man she has ever met.
"He's definitely not the most wonderful man I've ever me! Some people have said she's desperate to settle own and have kids, but she's gorgeous and could easily get someone better. I think she needs her head read!"
The happy couple announced the news on Instagram and posted a snap of them holding a balloon with the words 'Engaged' emblazoned across the front, but Chantelle was not impressed.
She added: "I hope the engagement balloon they were pictures with wasn't in place of an actual ring. Cringe!"

Miley Cyrus' beloved dog Floyd has died.
The 'Wrecking Ball' singer is completely devastated after one of her pet pooches, an Alaskan Klee Kai that she got in 2011, passed away yesterday (01.04.14) while she was on her 'Bangerz' world tour.
The heartbroken star posted on Twitter: "Today is the 2nd worst day of my life. I don't wanna say it because I don't want it to be real... But my precious baby Floyd has passed away. I am broken. I know I don't mean it but I wish he would've taken me with him this is unbearable. What am I gonna do without him? I am miserable."
Miley, 21, also apologised to her fans in advance if her performance is a little lacklustre at her Boston show tonight (02.04.14) after sharing two pictures of her cuddling up to the pup.
She added: "I'm sorry in advance if I am not myself tomorrow Boston. I will try my best to be my best."
The distraught Disney star's followers were sympathetic about her loss, and soon got "#RIPFloyd" trending on Twitter.
Miley - who owns several rescue dogs - is no stranger to coping with canine death after her Yorkshire terrier Lila was fatally attacked by her English bulldog Ziggy in December 2012.
The former 'Hannah Montana' singer even dedicated her performance at the 'VH1 Divas' concert to her departed mutt.
She wrote on Twitter at the time: "For everyone asking... I have never been so hurt in my life. My heart has never been so broken..... Lila my sweet baby girl has passed away."

The Wanted singer and 21-year-old beauty queen were reportedly spotted locking lips in Brighton, South East England last month and Amy has now fuelled rumours that they are officially a couple by posting a picture of herself with the 25-year-old hunk and his mother Barbara on a lunch date on Mother's Day (30.03.14).
Amy posted the image on Twitter along with the message: "Champagne & oysters 🙂 babs you are so awesome! (sic)"
Max's mum seemed to be taken with the blonde beauty as she also took to Twitter to let her followers know how much of a good time she'd had with her son and his new beau.
She wrote: "What an amazing day we had!!! Xxx (sic)"
Amy then responded to Barbara saying: "Such a nice day!! We are officially hardcore going on that big ride 🙂 follow me sweetie so I can message you other pics! X (sic)"
The British model - who won the title of Miss Universe last year - followed up the conversation with her love interest's mum with a picture of herself with him and a friend on Instagram.
The caption of the photo read: "Who wins best pout queen? @therealmaxgeorge in the lead with eye popping dedication! (sic)"
Amy and Max are said to have been seen kissing at the Vodka Revolution bar following the 'Glad You Came' hitmakers' concert in Brighton.
A source said: "They were having a great time together and were kissing all night."

Russell Brand is releasing a series of children's books.
The British comedian is producing his own "interpretation" of classic fairytales, 'Russell Brand's Trickster Tales', which will be illustrated by Chris Riddell.
Russell previewed an extract from the first book, an adaptation of 'The Pied Piper of Hamelin' in a video announcement.
He read: "Once upon a time, long ago, in a time that seemed to those present, exactly like now, except their teeth weren't so clean and more things were wooden, there was a town called Hamelin..."
The 'Despicable Me 2' star went on to explain more about his literary project.
He added: "I know you've already heard of that. And you might think, 'Well, that isn't your story'. Yeah, I know, I've done a different version of it.
"It's the first of series called 'Russell Brand's Trickster Tales', where I do interpretations of fairy stories and folk tales, believing them to be the code to unlock aspects of our consciousness and to affect and impact the way we see the world.
"Once we start changing the way children see the world... we can do all sorts of stuff."
In the video, the 38-year-old star also showed off accompanying illustrations of rats.
Russell has previously released two autobiographies, a tome about his passion for soccer, 'Irons in the Fire', and is also working on a book about his views on ecology, rioting, and "the total mistrust of politicians".

Johnny Depp hates reality shows.
The 50-year-old actor is terrified of the modern world's obsession with material goods and reality star icons, and believes the shallow craze will be the downfall of society in a few years' time.
He mused to Interview magazine: "It's really frightening. And when you see all this stuff that goes on in the commercials - the endless commercials - people yelling down your gob, 'Buy this, do this, this will save you, this will fix you.'
"Everything can be a reality show now. Imagine what's it going to be in 20 f***ing years, man."
Johnny - who is engaged to Amber Heard and has children Lily-Rose, 14, and Jack, 11, with former partner Vanessa Paradis - also went on to apparently slam stars like the Kardashians and Paris Hilton by lamenting that talentless socialites have become idols to a whole generation thanks to the phenomenon that is reality TV.
The 'Rum Diary' star added: "People get famous now for I-don't-know-what. People have reality shows because they're a Hollywood socialite, and these things become very successful and they generate a s**tload of money for the company.
"And it's multiplying, to where you're literally looking into your next door neighbour's bathroom with reckless abandon. It is like watching a fire. You can't take your eyes off of it."

McBusted have confirmed plans to record a new album.
The supergroup - comprised of McFly's Harry Judd, Tom Fletcher, Danny Jones and Dougie Poynter, as well as Busted's Matt Willis and James Bourne - contemplated "laying something down" before their tour which kicks off on April 17 in Glasgow, but were unable to do so since members had personal commitments.
While they have all been busy with tour rehearsals, Tom and his wife Giovanna welcomed their first child Buzz into the world on March 13 and he has also been trying to spend some quality time with the little one, while Matt has joined 'EastEnders' as Stacey Branning's boyfriend Luke Riley.
Talking to London's Capital FM radio station, Harry said: "We were thinking of going in the studio and properly laying something down before the tour started.
"We've had no time because of Tom having his baby, the tour rehearsals and Matt's filming bits on 'EastEnders'. Everyone has been so busy."
The boys plan on working their new record following the tour which ends on June 2 in Dublin.
He added: "It will happen after the tour. We'll be writing on the road and hopefully soon after the tour we'll get in the studio."
