Beyonce Teases Fifty Shades Of Grey Trailer

However, don’t get too hot under the handcuffs just yet - the breathy snippet isn’t quite the x-rated affair one might expect.

Unless knees are your thing, of course, in which case, your luck is in.

Beyonce’s dulcet vocal – re-tooled from her smash ‘Crazy In Love’ – adorns the clip, which has a brief glimpse of the back of Jamie Dornan’s Christian Grey in his upscale office, and those aforementioned knees.

It’s a precursor to the first full trailer, which will be unveiled on Thursday this week (July 24).

The hotly-anticipated movie, based on the record-breaking, best-selling erotic novel from EL James, stars Dornan as Grey and Dakota Johnson, daughter of Don Johnson, as Anastasia Steele.

Dornan took over from ‘Sons of Anarchy’ star Charlie Hunnam in the lead role, after Hunnam pulled out last year.

Also making up the cast are Eloise Mumford, Luke Grimes, Victor Rasuk, Jennifer Ehle and British singer Rita Ora.

Directing is artist and director Sam Taylor-Wood, and it’s due out in the UK on February 13, 2015.
