The Fifty Shades teaser trailer begins with this shot from the poster campaign

The soundtrack to the 15-second clip is a breathy 'uh oh' - the famous riff from Crazy In Love - which should explain Beyonce's excitement to post it.

She simply captioned the Instagram video with the hashtag #fiftyshades, not giving any more away, but this hasn't stopped the legions of Fifty Shades fans getting very excited about her involvement with the film.

The teaser - which really is teasing us - tells us that the full trailer for the Fifty Shades film will be released on Thursday, saying "the worldwide phenomenon will come to life." We can't wait.
