Christie Brinkley has been married four times, the most prominent of which was to musician Billy Joel of whom she appeared in several of his music videos but the marriage which has unfortunately been in the news the most was the one to architect Peter Cook. The marriage ended in a very public 2008 divorce and one of the main allegations was that he was a serial cheater.

The allegation was one that had men throughout social media stunned as the concept that a man married to one of the most beautiful women in the world would cheat on her and that he was a 'serial cheater' was mystifying but her allegations seem to have been proven correct and have social media fans trumpeting her good decision on 'kicking him to the curb'.
Her ex-husband is reportedly separated from Suzanne Shaw, the woman that stood by him during his bitter custody battles with Christie Brinkley after their 2008 divorce and later became his wife.

Christie Brinkley's ex seems to have moved on once again as the tabloids have reported that he was recently spotted in the Hamptons with a young blonde woman whom he is introducing to people as his girlfriend.
Interestingly, while he is being given the boot for being a serial cheater the beautiful ex-Cover Girl model is still in the public eye for being beautiful. She was recently in the news for being part of a Air New Zealand flight safety video along with two other Sports Illustrated models which the airline had to remove because of allegations that the attractive women in the video made the film look 'sexist' and also for supporting her daughter's burgeoning modelling career.
One might fathom a guess that Christie Brinkley is likely enjoying her time in the public eye more than her ex-husband.
