Cassie strips down to her bra and panties in a teaser for the ck one lifestyle collection. Directed by famed photographer Steven Meisel, the black-and-white clip evokes the controversial Calvin Klein commercials of the ’90s, with models, musicians, actors, and sports stars parading around in little clothing. The shaved-head hottie is seen fighting with a male co-star while Kelis’ “Caught Out There” plays in the background. Check out her sexy cameo below before the full campaign rolls out next month.
