Kylie Minogue interrupted a fan's gym session to perform her new single.
The 'Spinning Around' hitmaker left fan Adam Milner stunned when she arrived unannounced during his workout at The Factory Gym and Dance Centre in London to perform her song 'Into the Blue' for the first time, after she heard he listens to her music whilst exercising.
Adam - who was busy doing sit-ups - gasped as Kylie, 45, sashayed into the room accompanied by glitter cannons, before hunky dancers disguised as fellow gym members joined the star for the performance of her new single.
Speaking of the performance, Kylie said: "I've never performed in a gym before, so it was a crazy and exciting experience for both me and my fan, Adam.
"I loved Adam's reaction when I walked in and even in his shocked state he still managed to sing along to all the word."
Kylie's performance comes as part of a string of surprises in conjunction with Mastercard's #PricelessSurprises campaign which sees a host of stars such as Pharrell Williams and 'Green Garden' singer Laura Mvula surprise their biggest fans.
All of the videos will be interspersed between the ad breaks during the BRIT Awards tonight (19.02.14) which airs on ITV at 8pm.

'Downton Abbey's' Lady Mary Crawley may choose Lord Gillingham over her other suitors in the new series.
The widowed character - played by Michelle Dockery - was seen fending off advances from numerous eligible bachelors in the last series of the ITV period drama, but new pictures from the set of the fifth series suggest she may have picked her man.
Michelle and actor Tom Cullen, who plays Lady Mary's childhood friend, were seen shooting a steamy kiss after emerging from a hotel. The scenes take place in Liverpool but were shot in London this week.
An onlooker told The Sun newspaper: "The scenes looked very cosy.
"There was an affection there that you would expect from a couple in a relationship.
"But who knows what is in store for them next series."
In the last series of 'Downton', Lady Mary - whose husband Matthew Crawley (Dan Stevens) was killed off in the 2012 Christmas special - turned down Gillingham's marriage proposal and was torn between three suitors, including Charles Blake (Julian Ovenden) and Evelyn Napier (Brendan Patricks).
Meanwhile, 'Downton' newcomer Richard E. Grant has promised his character, house guest Simon Bricker, will "shake things up" when he arrives at the famous Crawley home.
Richard teased: "I started filming yesterday.
"When I stepped on to the set at Highclere, I thought, 'Yes, I'm home'. I'm upstairs, naturally!
"I don't want to spoil anything but my character is set to cause some ructions. He definitely will shake things up. It's going to be fun."

Ant and Dec are planning to take 'Saturday Night Takeaway' to the United States.
The presenting duo are TV favourites in Britain but have so far been unsuccessful in their attempts to launch a career in America, although they are now said to be in talks about launching the hit show over there.
Dec said: "There has been some interest from the States. We have had a couple of meetings over there about it. It could be called 'Saturday Night Take-Out'!"
The stars - full names Anthony McPartlin and Declan Donnelly - failed to win over audiences when they took their series 'Wanna Bet' to the US in 2008 but have continued to win prizes for their on-screen chemistry in the UK.
A source told the Daily Mirror newspaper: "The boys are still the biggest names on TV here ... but they are very ambitious so they would love to go to America and have a hit."
The pair could follow in the footsteps of their former 'SMTV Live' co-host Cat Deeley - who has presented American dance contest 'So You Think You Can Dance' since 2006 - and they haven't given up on their dream yet.
Ant said previously: "We will probably try our luck in America again. It would need to be the right show. I think we've got one big push left."
It's been suggested that Ant and Dec will take 'Saturday Night Takeaway' to the US in 2015 after they've finished working on the upcoming series of 'Britain's Got Talent' and 'I'm a Celebrity ... Get Me Out of Here!'.

Robert Lindsay insists he will never return to 'My Family'.
The actor played Ben Harper in the BBC family sitcom between 2000 and 2011, but he has ruled out a revival for the comedy, which also starred Zoe Wanamaker as his wife Susan.
He told Digital Spy: "Oh no! No, no, no, no. That's gone now.
"The kids are 45! When the kids kinda went like that you went, 'Oh...' "
"I don't like returning to things anyway."
The 64-year-old star went on to suggest he continued starring in the series - which screened 11 series and numerous Christmas specials - for longer than he had originally intended.
He said: "I did 'My Family' for a really long time and for reasons that I will not go into here ... one of which was Zoe 'cos I loved her so much.
"It was just a very convenient job - it was Pinewood Studios, which was just a hop, skip and jump from where I lived."
Robert starred in all but three of the 120 episodes of 'My Family', while Zoe appeared in 115 episodes.
The series also starred Gabriel Thompson, Daniela Denby-Ashe and Kris Marshall as the Harpers' children.

Conor Maynard says he won't make the same mistakes as Justin Bieber because he's "good at not breaking the law".
The 21-year-old singer recognises there are temptations all around for young pop stars like himself and 19-year-old Justin, who has had several run-ins with police recently including being arrested and charged with driving under the influence (DUI), resisting arrest and driving without a license in Miami in January.
Conor has assured his fans he has no plans to copy his pop peer but he does have sympathy for the pressure Justin must be under as one of the world's most famous musicians.
The 'R U Crazy' hitmaker quipped to BANG Showbiz: "I don't worry about ending up like Justin. I can just not do any illegal stuff! I feel like I'm good at not breaking the law. That's always a good trait to have as a person.
Speaking about Justin's situation, he added: "As an outsider looking in I feel like that maybe he feels as though he can't do anything right, no matter what he does he's going to be shot down. Maybe in he thinks, 'If you want me to do things wrong, I'll show you.' But you never know what's going on in people's heads, you never know the pressures and the stresses that Justin has."
Conor - who is busy working on his second album - insists he has been able to stay grounded because he has kept a close group of trusted friends around him that knew him before he became famous.
The singer - who performed at the Brooklyn Bowl as part of BRITs Week at The O2 on Tuesday night (19.02.14) and was supported by Lewis Watson - explained: "I've kept the friends I already had, 100 percent. I've heard that advice from a million people. When Wiley and I shot our video to 'Animal' lots of my friends came down and Wiley said, 'Make sure you keep your friends around as much as you can and for as many things as possible.' I've taken that advice on board and keep the same people around me. At the moment I've got the right people around me that keep me on the right path."

Jaden Smith has reached out to Shia LaBeouf, insisting he has a "fellow insane" friend in him.
The 15-year-old star tried to visit the 27-year-old Hollywood actor - who wore a brown paper bag over his head to the German premiere of his new film 'Nymphomaniac' earlier this month and has repeatedly insisted he is no longer famous - at his #IAMSORRY silent art installation in Los Angeles, and though they never got to meet, Jaden wants Shia to know he is "seriously" there to give him support.
Jaden - who is the son of actors Will Smith and Jada Pinkett Smith - wrote on Twitter: "I Waited In Line Today On Beverly Blvd To See @thecampaignbook I Never Got See Him But I Had A Very Important Message To Deliver.
"I'm Here If You Need A Fellow Insane Person To Talk To. But I'm Seriously Here Not Like One Of Those I'm Here For You's That Everybody Says. (sic)"
Jaden - who only follows Shia on Twitter - added: "It Was A Message That Only Could Be Understood Artist To Artist. @thecampaignbook I'm Here For You I Believe In What Your Doing (sic)"
Meanwhile,Shia's 'Nymphomaniac' co-star Felicity Gilbert is concerned his recent antics are "dangerous" because the public don't understand what he is doing.
She told The Metro newspaper: "I think this is his own project. His own creation. But I think people don't necessarily sympathise with him that easily and so it is a dangerous thing to do."

Kanye West is making a movie with Brett Easton Ellis.
The controversial author was initially reluctant to work with the 'Bound 2' hitmaker, but was instantly won over when he heard the rapper's latest album 'Yeezus', though he is unsure when the project will go ahead.
He said: "It's in Kanye Land, and that's subject to a whole other time frame." offered Ellis on the status of the film.
"He came and asked me to write the film. I didn't want to at first. Then I listened to 'Yeezus'. It was early summer last year and I was driving in my car. He'd given me an advance copy, and I thought, regardless of whether I'm right for this project, I want to work with whoever made this. So f**k it, I said yes. And that's how it happened.
"That was seven or eight months ago. We'll see what happens."
As well as being a fan of Kanye's music, the 'American Psycho' author finds him a fascinating person, though he admits he doesn't always come across well to the public.
He added in an interview with Vice: "I really like him as a person. I know he comes off in this performance-art way in the press, but if you're just alone with him in a room talking for three hours, it's kind of mind-blowing."

Nicole Richie was "crawling on all fours" while watching Britney Spears in Las Vegas.
The reality star-turned-fashion designer went to support the 'Perfume' singer during her residency at Planet Hollywood Resort and Casino last night (18.02.14) and enthusiastically danced and sang along to the show.

Nile Rodgers got sober because he worried his lifestyle would destroy his musical ability.
The Chic guitarist - who is expected to perform with Pharrell Williams at tonight's (19.02.14) BRIT Awards - admits drugs used to be an "important" part of his life, but he quit his habits because his career meant more to him than partying.
He said: "I felt that that would be an impingement on my ability to play music.
"I remember reading an article by Keith Richards saying he could live without drugs but he couldn't live without music and I feel exactly the same way.
"My life revolved around music but drugs were an important component, just as much so as any intellectual property or breathing or eating food."
Nile realised he needed to get sober when his behaviour at Madonna's 35th birthday party stunned his friends.
He told Metro newspaper: "As of Madonna's next birthday, if I'm lucky, it will be 20 years since I've had a drink or drug in my body, which is the most remarkable, incredible thing.
"It was her party down in Miami Beach. I remember it not because I have a conscious memory of it but because everybody filled in the blanks for me when I was writing my autobiography.
"I have first-hand testimonies from people who were completely aware and sober going, 'Oh my God Nile we've never seen you like that', and that was all I needed to hear, people that I trusted telling me for all intents and purposes I had gone mad."
