Christie Brinkley's ex-husband Peter Cook says days after their Long Island divorce trial he's sorry he got involved with the 18-year-old who helped wreck their marriage. The couple were married for a decade before the 49-year-old Cook met Diana Bianchi and began a sexual relationship with her.

Bianchi says Cook showed interest in her and she reciprocated until their relationship ended in late 2005.

Cook tells the Fox News Channel in a Sunday interview if he had the chance to do it again he'd say: "No, I'm a married man."

Brinkley and Cook's divorce trial ended Thursday following a week of testimony about Cook's affair and online porn habit.

Brinkley gets custody of their two children and properties. Cook gets $2.1 million.

Cook says he's satisfied with the agreement.
