Christie Brinkley BrinkleyContempt.jpgWow, just when you thought this divorce couldn't get any nastier!

Christie Brinkley's ex-husband Peter Cook (you know - the guy who had the affair with the teenaged girl) has asked a New York Judge to hold the former supermodel in contempt of court because she allegedly wouldn't give him their son's passport, Newsday reports.

Cook had reportedly wanted to take their 13-year-old son Jack on a school trip to Egypt in November. The teen reportedly missed the trip as a result.

Brinkley's lawyers called the claims "baseless and really rather petty."

We're inclined to agree.
