NEW YORK - Christie Brinkley's ex-husband Peter Cook says 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 told the Fox News Channel on Sunday 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 got custody of their two children and properties. Cook got $2.1 million.

Cook says he's satisfied with the agreement.
