Beyonce taps into her sexy side by lending some sultry vocals to the teaser for the forthcoming film 'Fifty Shades of Grey.'

The singer revealed the teaser through a post on her Instagram account over the weekend. Bey moans to the melody of 'Crazy in Love,' her 2003 hit duet with hubby Jay Z, in the visual.

“Uh oh, uh oh, uh oh, oh no no,” she coos.

From a shot of Christian Grey's backside to Anastasia Steele's skirt being lifted up, the singer's vocals serve as the soundtrack to a montage of shots presumably from the film, The new dark and slowed down version of the song fits perfectly with this fantasy-driven, sexual project. And considering Rita Ora, who's signed to Jay's Roc Nation, is also playing Mia Grey in the movie, perhaps there will be some legit contribution from the Beyonce and Jay Z camp.

The full version of the trailer debuts Thursday (July 24). In the meantime, check out the teaser above.
