Well here’s something else for Christie Brinkley to be bitter over: the release of ex-husband Peter Cook and some 18 year old assistant’s sex tape.

Stills from an explicit home video allegedly show Christie Brinkley’s ex-husband Peter Cook having sex with 18-year-old assistant Diana Bianchi, the New York Post’s Page 6 confirmed on Thursday.

According to Page 6, the stills depict the couple nude and having intercourse on a brown love seat. They also show Bianchi performing a striptease as Cook holds his crotch.

Diana Bianchi claims not to have known that Peter Cook was video taping her, but either way, would it have made a difference to a slut like her?  Well, yes, actually.  She probably would have walked away with a ton of “hush-hush” money that would have made Peter Cook feel like he was ass raped instead of rubbing on her ass.  Now instead, he might have to face Christie’s lawyers–who will probably show no mercy nor tail.
