Another Peter Cook Mistress to Testify This Week

Yet another chick linked to that assbag Peter Cook since his breakup with Christie Brinkley will be unveiled at his divorce hearing this week.

Bridget Nisivoccia is a pretty, blond interior designer who told the New York Daily News she was hired to design Cook's home in Sag Harbor, L.I.

She is expected to become part of the blockbuster trial this week when another witness discusses Nisivoccia's connection to Peter Cook.

The 36-year-old Nisivoccia joins a growing list of women in Cook's life since his 10-year marriage to Christie Brinkley dissolved in 2006.

The source did not say Peter Cook and Bridget Nisivoccia were involved.

However, Diana Bianchi also worked for him, remember. Just saying.

Insisting there was no railing by Cook going on, Nisivoccia said: "We have mutual clients and share a professional relationship and a respected friendship."

Fitness model Carri Lyn Ciamarra, a married Westchester mom who dated Peter Cook for about six months last year, has been called to testify.

Ciamarra, who says she will fight the summons, was subpoenaed along with Cook's current squeeze (yup, he still reels 'em in), Suzanne Shaw.

As week two of the Brinkley-Cook divorce trial begins today, both sides will begin the battle over custody of the couple's two kids.

Last week, the two sides fought over the grounds for the divorce, and sordid details emerged of Peter Cook and his penchant for Internet porn.

Diana Bianchi, who had an affair with Cook while a teenager, also said that he showered her with gifts and left her money under rocks. Standard.
