Rumors of an explicit home video showing Christie Brinkley's slimy hubby Peter Cook having sex with his curvy teen office worker Diana Bianchi have made the rounds for months, and now Page Six can reveal the truth - it does exist.

Yesterday, we were shown a series of stills from a video depicting Cook and Bianchi, both nude, having sexual intercourse on a brown love seat. They also show Bianchi performing a sizzling striptease down to a pair of black, G-string panties and then to her birthday suit as Cook holds his crotch.

Another shows Cook resting his head on Bianchi's buttocks. It appears the tape was made at Cook's Southampton architectural office without Bianchi's knowledge. But other stills that are apparently not from the video show Bianchi willingly posing topless.
