Turns out rumors of Christie Brinkley’s ex, Peter Cook, and Diana Bianchi having a sex tape are real. There is a Peter Cook/Diana Bianchi sex tape making the rounds.

The sex tape scandal is just the latest scandalous happening in the case of Peter Cook cheating on Christie Brinkley. The sex tape shows Peter Cook having sex with his teenage assistant, Diana Bianchi, on a brown love seat in his Southampton architectural office.

Christie Brinkley and Peter Cook settled their divorce in July – he made off with a chunk of her money, but she got full custody of the kids. Cook also confessed to an online porn habit at the time and paid out $300,000 to Diana Bianchi to keep her quiet about their affair.

Quite the scumbag.
