Some may call him a cad, a douche, a home wrecker, but one thing that Peter Cook is not? Well, he’s not waiting around. Peter, who is Christie Brinkley’s cheating ex-husband, brought his new girlfriend to the Hampton Classic Horse Show a few days ago in New York City, New York. Of course, Peter is well-known for his affair with his 18-year-old assistant while married to Christie. We just hope that the new girlfriend, who’s name is Suzanne Shaw, knows what she’s getting into.
