#4 - Christie Brinkley and Peter Cook

Model Christie Brinkley settled her divorce with fourth husband, architect Peter Cook, earlier this summer. Brinkley filed for divorce in 2006, 10 years after the couple married. The public battle made headlines after Cook admitted that he had had an affair with Diana Bianchi, 18, and paid her $300,000 to keep her from filing a lawsuit against him. He also admitted spending $3,000 a month on Internet pornography and posting a video of himself masturbating on the Internet. The couple settled out-of-court in July, with Brinkley paying $2.1 million in exchange for custody of their two children and some property.

Brinkley was previously married to artist Jean-François Allaux, musician Billy Joel and real estate developer Richard Taubman. She has three children: daughter Alexa Ray Joel with Billy Joel, son Jack Paris with Richard Taubman and daughter Sailor Lee with Cook. Jack was later adopted by Cook.
