Model Christie Brinkley is set for further heartbreak once a new TV interview with her ex-husband Peter Cook airs on Friday night. The couple divorced after a messy court battle in the summer, during which Brinkley accused her ex of being addicted to internet porn.

Brinkley and Cook split after the model learned of her husband's affair with a teenage assistant— from the girl's concerned parents.

Now Cook is going public with the problems that lead to him straying as part of an interview on news show "20/20." He reveals his affair began when he failed to get the emotional "connection" he craved from his wife.

He explains, "There came a time when I pulled up the driveway to the home that I found, that I built, that I lived in— and I felt like I was a guest in someone else's life. I was seeking a connection I could not find in my own marriage. I think I just suddenly realized when I was getting attention from someone else that this is something that was missing in my life."
