New York (ANI): A video showing Christie Brinkley's hubby Peter Cook having sex with his curvy teen office worker Diana Bianchi is for real. The video, which has made rounds of Internet circles, shows nude Cook and Bianchi having sexual intercourse on a brown love seat. The tape apparently made at Cook's Southampton architectural office without Bianchi's knowledge also shows her performing a sizzling striptease.

It was in July that Brinkley divorced philandering Cook owing to his affair with then-18-year-old Bianchi. She also won full custody of their kids. "Nothing about Peter Cook's behavior shocks us. We don''t know anything about this tape. We never saw it and we never heard about it. Christie's concern is for the sake of her children and she hopes this video is kept private," The New York Post quoted Brinkley's lawyer Robert Cohen, as saying.

However, Bianchi's lawyer, Joe Tacopina, said she might sue Cook over the video. "We are now going to review, and begin weighing our legal options, for Diana," he told The Post's Dan Mangan. While Cook refused to comment on the issue, a source close to him said: "He has no knowledge that any such material exists, but it is well known that Cook and Bianchi had a consensual affair, so anything is possible."
