BEYONCE has published a trailer of Fifty Shades of Grey on her Instagram, suggesting that she is to have some involvement with the film's soundtrack.

The short clip features a remix (code for hypersexualised version) of the singer's Crazy in Love track, as well as some heavy breathing and a close-up shot of what are the hands and legs of presumably Jamie Dornan and Dakota Johnson, who star as leads Christian Grey and Anastasia Steele.

Other 'highlights' include a shot of Dornan's back as he stares, probably broodingly, out a window.

Beyoncé added little more to the trailer, other than a caption reading "#fiftyshades".

But suffice to say, it's not unimaginable that the singer's breathy, charged voice will appear on the soundtrack in some capacity.

Or maybe she and Jay-Z are just huge fans of the books.

EL James' original book trilogy of the same name has become one of the biggest-selling literary series of all time, selling 100million copies worldwide.

Fans reacted with delight, with one writing: "Don't have to wait much longer. Yay."

Another wrote: "Are you serious I've been waiting for this my whole life."
