It may be too little, too late – but architect Peter Cook now says he's sorry for the tryst that destroyed his marriage to Christie Brinkley.
In 2006, the discovery of Cook's yearlong affair
with Diana Bianchi – a teenage employee at his firm – effectively ended his decade-long marriage to the supermodel.
If he had the chance to do it over, Cook told the Fox News Channel on Sunday, he'd say: "No, I'm a married man."
Brinkley and Cook's divorce trial ended Thursday
, after a week of bruising testimony
about his expensive online porn habit and alleged anger management issues.
The couple's last-minute out-of-court settlement
granted Brinkley, 54, custody of the duo's two children and multiple real estate properties. Cook meanwhile got "parenting time" with Jack, 13, and Sailor, 10 – along with a payment of $2.1 million.
Over the weekend, the 49-year-old also told reporters he has no regrets about his union.
"I'll never regret marrying her," he told reporters Saturday, the New York Post
reported. "We had a great time for 10 years. I've got two beautiful children."
