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.''
