I believe Ali Landry divorced Mario Lopez almost immediately after they were married because she discovered Mario was constantly cheating... What better way to tell the world about your impending divorce to a cheater than talking about the details to a divorced cheater? (If he was dressed as AC Slater, that would be a better way.)
On another note, did we really expect Tony Parker to be faithful? He was 25 when he married her. Yes, she is extremely attractive, but let me say it again -- he is a 25-year-old NBA player! And he's a good-looking fellow. And he's a three-time NBA champion. And he has a French accent. And he has tons of money.
To say "chicks dig him" would be an understatement.
