Hawt -- we're talking 4-alarm fire. Supermodels Joan Smalls, Chanel Iman and Jourdan Dunn get up close and personal with Beyonce in the diva's super sexy 'Yonce' video.

Smalls even licks Bey's cleavage in one scene, while Bey, who is sucking on a lollipop, looks totally bored by the amorous gesture. Rawr!

The four ladies are quite a stunning crew. The vid is super sensual, focusing on glossy lips, grills and grooves, along with a little twerking on Bey's part.
