Diana Bianchi was caught on a sex tape with Christie Brinkley’s ex husband Peter Cook. She was in shock after finding out that she was being secretly taped.

The sex video shows a totally naked Peter Cook and his teen office worker Bianchi having sexual intercourse on a love seat.

“She is devastated to learn about these surreptitiously recorded sex tapes,” said Bianchis lawyer, Rosemarie Arnold. “She had no idea she was ever being recorded,” she added.

The steamy sex tape was shot at Cook’s Southampton architectural office without Bianchi’s knowledge. It also shows her performing a sizzling striptease.

“I have no comment on this crap. I don”t know what she’s doing or why she’s doing it,” said Cook.
