Cassie has dropped a very sexy, photo shoot-like teaser for her upcoming video for the Jadakiss-assisted single, 'Make You a Believer.'

The 24-year-old model-turned-singer and actress practically fogs up the camera lenses with her sultry gaze and barely-there outfits on set of the shoot. "Gimme your sex appeal, so I can take you home," Cassie sings. "You wanna ride my roller coaster?" she asks. Guess you have to give it to her for being straightforward!

No sign of featured rapper Jadakiss in the teaser, but we're looking forward to seeing the full video for this funky, mid-tempo track after this ... revealing ... behind-the-scenes preview.

'Make You a Believer' is taken from Cassie's upcoming second studio album 'Electro Love,' which will feature collaborations with everyone from Lil Wayne to Nicki Minaj to Akon, to her producer Diddy, to whom she has been romantically linked.
