Beyonce has hinted that she will perform on the 'Fifty Shades Of Grey' soundtrack.
The 32-year-old singer posted a teaser trailer for the raunchy movie on her Instagram account along with her crooning a sensual version of 'Crazy In Love'.
'Fifty Shades Of Grey' stars Jamie Dornan and Dakota Johnson - who play bondage loving billionaire Christian Grey and virginal Ana Steele - can be seen writhing around naked in the teaser, with the full trailer to follow on Thursday (24.07.14).
Beyonce simply captioned the video #fiftyshades, leaving fans guessing as to her involvement.
It is unclear how Beyonce got involved in the project - which has been directed by Sam Taylor-Johnson - but her husband Jay Z's protege Rita Ora has a small part in the movie.
The 23-year-old singer tries her hand at acting in the new blockbuster adaptation of E.L. James' best-selling erotic novel and she admitted she was so nervous about her role - playing Christian's sister Mia - she worried she would mess up.
Speaking in May, she said: "I've just shot the movie, 'Fifty Shades of Grey'. That took up a lot of my time as I didn't wanna embarrass anybody, so I made sure I knew exactly what I was doing.
"It was an incredible experience. I went from not knowing what it's like being on a movie set, to feeling like I knew them all for years, and I wasn't even there for that long."

Radiohead's Jonny Greenwood has been emailing song ideas to Thom Yorke for the band's new album.
Jonny has revealed that new Radiohead material is in the works after a year-long hiatus and he and Thom are in constant contact about new compositions.
Talking to The Sunday Times, Jonny explained: "I was emailing stuff to Thom last night, actually, but it's not the same, is it? You don't see him tutting."
The band took a break after touring with their last album, 'The King Of Limbs', but Jonny, Thom and bandmates Colin Greenwood, Phil Selway and Ed O'Brien are ready to get back to work together.
However, fans can expect to wait a while before hearing any of these new songs.
When asked if the group has a release date in mind, Jonny said: "No! Release? No, no idea. No.
"Our plan is to start making music soon. We've just got to get the inertia back."
In the past, Jonny has stated that the band will reunite in the studio in September.
Speaking on the BBC 6Music show, he told presenter Mary Anne Hobbes: "We're going to start up in September, playing, rehearsing and recording and see how it's sounding."

Su Pollard has spurned the opportunity to take part in 'I'm a Celebrity... Get Me Out of Here!'
Bosses of the popular ITV show had wanted the comedy actress - who is best known for playing Peggy Ollerenshaw in 1980s sitcom 'Hi-De-Hi' - to appear on the next series, but Su admits she is too scared to participate.
The 64-year-old star explained: "It's a great show but I've had to say no. I hate creepy crawlies and spiders and snakes, and I just know that I'd be a screamer that everyone picks on."
She added to the Daily Star newspaper: "I couldn't eat giraffe balls. I couldn't do those trials.
"The campers would end up anorexic by the end of the show."
Su's attention is currently firmly fixed on rehearsing for the role of Maid Marian in a new comedy based on Robin Hood, called 'Ha Ha Ha Hood and The Prince of Leaves', which is to debut in Chelmsford on August 19.
The next series of 'I'm a Celebrity' - the fourteenth in total - is to hit to screens later this year.
Last year's jungle competition was won by former Westlife singer Kian Egan.
Notable contestants included Joey Essex, Amy Willerton and David Emmanuel.

'24' could return for another season.
Peter Rice - CEO of FOX, which airs the hit show in the US - has suggested Kiefer Sutherland could reprise his famous role as Jack Bauer once again following the success of recent miniseries '24: Live Another Day'.
The counter-terrorism drama was revived after a four-year break as a 'limited event series' consisting of 12 episodes.
Talking at a Television Critics Association event on Sunday (20.07.14), Peter enthused: "I loved this year's season of '24', I thought it was fantastic. I've always been a fan and it just twisted and turned, and I could never guess where it was going. We haven't had a specific conversation about it coming back yet. I'm sure that we will in the future."
Peter went on to praise the cast and crew and expressed his belief that '24' still has "many more stories to tell".
He added: "It's a wonderful franchise, Kiefer and Evan [Katz] and Howard [Gordon] and Manny [Coto] did a great job this year.
"So when you look at the show itself, it has many more stories to tell, but I think we have to sit down and talk to the creators about it."
'24' originally aired from 2001 to 2010, earning numerous awards, but ended after eight seasons, each consisting of 24 action-packed episodes.
Kiefer and long-time co-star Mary Lynn Rajskub (Chloe O'Brian) both returned for the 2014 revival which was filmed in London.

'Gracepoint' will end in a "very different place" to 'Broadchurch'.
Producers have promised the US remake of the murder mystery drama will blaze its own trail, despite the early episodes appearing to be a carbon copy of the ITV show.
Speaking at a Television Critics Association event yesterday (20.07.14), showrunner Dan Futterman explained: "I don't want you to rule anybody out as a suspect. We end in a very different place, which is both exciting for the first season - and what could be a great second season as well."
'Gracepoint' executive producer Carolyn Bernstein revealed the reason the early episodes are so similar to the British version is because she and Dan felt show creator Chris Chibnall's scripts were perfect and didn't want to make unnecessary changes.
She explained: "We did consider starting in a different place for the fist episode, but the first episode of 'Broadchurch' was so well done. Why contort ourselves when that was the smartest way to go?"
But Carolyn went on to "promise" Gracepoint's plot would unravel into fresh storylines that viewers won't see coming.
She added: "As this series progresses, it really diverges. We're not particularly worried about the overlap."
David Tennant reprises his role from 'Broadchurch' - albeit with an American accent - as the show's lead detective. 'Breaking Bad' actress Anna Gunn, Michael Pena, Jacki Weaver and Nick Nolte star alongside him.

Vin Diesel says 'Fast & Furious 7' was the "hardest movie" he's ever made.
Filming has now wrapped for the seventh instalment of the film franchise and actor Vin Diesel has opened up about the pain of losing his co-star Paul Walker in a tragic car accident in late 2013.
Talking to Access Hollywood, Vin reflected: "It was surreal. Needless to say the hardest movie I've ever done.
"I remember when the tragedy happened. My mother said, 'It's not fair that you have to mourn in front of the world'.
"What's even harder is to mourn and simultaneously pretend that that person is next to you. It's very, very weird."
Paul - who played Brian O'Conner in the films - died in November last year while in the passenger seat of a car being driven by his friend Roger Rodas.
The car burst into flames after hitting a lamppost in California and it's thought that the vehicle could have been travelling at up to 100 miles per hour.
Sadly, Paul died before finishing filming his scenes for 'Fast & Furious 7' and his brothers Caleb and Cody Walker were asked to fill in for their late sibling as a body double, so that the movie could be completed.
Dwayne "The Rock" Johnson - who also stars in the film - previously confessed that completing the project was "bittersweet".
He shared: "Last day on set, it was bittersweet. It was emotional, it was beautiful. It was amazing, it was sad, it was all those things. We are all in the business we all know and love Paul Walker and we truly lost one of the good ones."
He added: "My number one thought is for his daughter [Meadow Walker]. I believe she is doing okay. I think she's doing as okay as she can."

J.J. Abrams has hinted that an X-Wing starfighter will feature in 'Star Wars: Episode VII'.
In his latest video from the set of the highly anticipated next instalment of the sci-fi film series the director addresses fans while standing in front of the iconic aircraft.
The 'Star Trek' filmmaker previously posted a video from Abu Dhabi in the United Arab Emirates, where a number of sequences for the film were shot, offering fans the chance to appear in the movie in return for them donating money to Unicef via 'Force for Change', and he's now extended the prize.
Speaking from Pinewood Studios in Buckinghamshire, South East England, with the vehicle partially responsible for the destruction of two Death Stars looking slightly modified and beat up in the background, he said: "People from over one hundred and nineteen countries have already participated ... But we're still going. We have one week left, so for this final week we're giving you and a friend the chance to visit the set of 'Star Wars: Episode VII' and be in the movie."
It's yet to be revealed who will be flying the X-wing starfighter, but Abrams is planning to give a dedicated fan the chance to find out before the film's December 2015 release date.
He continued: "We're offering something else. A chance to win an advance screening of 'Episode VII' before it hits theatres. By supporting 'Force for Change' you could win a private screening of the movie in your hometown and invite twenty of your closest friends and family.
"We know how much Star Wars means to so many of you and we'd love to share the movie with you first while supporting this truly great cause."

Nicole Richie gets her sense of humour from her father.
The 'Candidly Nicole' star is delighted singer Lionel Richie makes a number of appearances on her new reality show because he isn't afraid to laugh at himself.
She told the New York Daily News newspaper's Confidenti@l column: "He and I have very similar senses of humour.
"He's one of my favourite people to have on the show. Like me, he is down to be the butt of any joke as long as it's making people smile and laugh."
The 32-year-old star - who has children Harlow, six, and Sparrow, four, with husband Joel Madden - is very close to her father and always has a good time with the 'Dancing on the Ceiling' singer.
She added: "I'm so comfortable with him. We have that very comfortable banter. He's always down to have fun."
While Nicole is happy to have Lionel on her show, she recently admitted her kids won't be making appearances as they won't even allow her to share pictures of them online.
She said: "They don't even like me sending pictures of them to their grandparents. They definitely wouldn't be happy with me sending it out to millions of people."

The Rolling Stones are obsessed with TV box sets.
The veteran rockers shun wild parties for more leisurely pursuits on the road these days, including backgammon, jigsaw puzzles, and binge-watching television shows.
Guitarist Ronnie Wood said: "Being on tour jetlags you. You wake up every night about 9pm, just at the time when you would be going on stage. So now, instead, we watch 19 murder mysteries in a row. We're on 'Above Suspicion' at the moment. Last one tonight.
"We watch loads of box sets on the road, too. Even with [Sir Mick] Jagger I go, 'Let's go and watch 'House of Cards'.' And he told us about 'Game of Thrones'. We had to send someone out at four in the morning when we were in Shanghai to get us the next series."
The group are all big fans of 'Breaking Bad' and were delighted to meet Aaron Paul, who played troubled Jesse Pinkman, at one of their gigs.
Ronnie's wife Sally said: "When Aaron Paul came backstage at a gig, that caused more pandemonium than even the band."
Ronnie added to the Daily Telegraph newspaper: "We cracked the ice with him. Keith was going, 'What are you doing here?' and Patti [Keith's wife] was like, 'Oh my God, get out of the way. It's Aaron!' "

Cher Lloyd finds life "easier" because she is married.
The 20-year-old singer - who married Craig Monk in November 2013 after almost two years together - insists their relationship is no different since they tied the knot, but she appreciates having a "consistent thing" in her life.
She said: " I don't think it has [changed being married] we just get on with life together. It is a lot easier for me now because I feel like my life is so hectic, it's nice to have one consistent thing that I know is always going to be there and be supportive and be on that path with me."
The 'Sirens' singer - who shot to fame after competing on UK TV talent show 'The X Factor' in 2010 - has enjoyed huge success in America, which she thinks is due to her willingness to work hard.
Discussing cracking America on TV show 'Lorraine', she said: "It's very difficult, I think it's a mixture of luck and hard work really... I think it's really just getting your head down and going for it... You only get back what you put in."
And while Cher is currently focussed on her music career, she wouldn't say no to trying her hand at acting in the future.
She said: "I'm not tempted [to go into acting at the moment] I've been very fortunate to get a little bit of interest in that area but I'm completely focussed on my music at the moment but it's something that I wouldn't mind doing later on."

Scott Disick's aunt thinks the deaths of his parents caused him to drink excessively.
The 'Keeping Up with the Kardashians' star was recently hospitalised with alcohol poisoning, and Audrey Martone thinks the death of her brother Jeffrey just a few months after his wife Bonnie has hit her nephew hard.
She told RadarOnline.com: "Scott lost both parents in a very short period of time, and I think being without them right now is a sad reminder.
"I feel for him and I try to give him the benefit of the doubt. Everyone has their own way of grieving, and I respect that."
Scott is currently filming 'Kourtney & Khloe Take The Hamptons' with his long-term partner Kourtney Kardashian - who is pregnant with their third child - and her sister Khloe, and Audrey is worried that filming so close to his childhood home in New York may trigger some painful memories for him.
She said: "They're out in an area of Long Island where there are reminders of his parents. He might need some time to heal."
Audrey also admitted she only found out about Scott's hospitalisation in June through the media as she hasn't heard from her nephew since the beginning of the year.
She said: "I didn't know anything. Someone from work actually told me they read about it."

Daniel Radcliffe was happy to sign autographs and pose for selfies with fans in New York as he greeted the crowd outside The Cort Theatre.
