Christie Brinkley continues her courtroom battle with ex-hubby Peter Cook, whose affair with 18-year-old Diana Bianchi brought down their marriage. Now, the supermodel's lawyers may have more ammunition against her wandering ex; another alleged affair with a married 31-year-old fitness trainer!
The NY Post reports that Cook moved on from his teenage mistress to Carri Lyn Ciamarra -- only to break up with her when she left her hubby. Former NY prosecutor Janine Pirro dished to "Extra" about Brinkley's ex, saying, "Everybody knows he's a horndog. Everybody knows he's the kind of guy who probably shouldn't be married."
Brinkley and Cook continue their divorce battle in court. They have one daughter, Sailor, 10.
