They used to hate each other. A lot. He creeped her out. She used to feel sick when she saw him. Now though, this A list all movie actress has changed her tuned and has been sharing the bed with this A+ list all movie actor. The problem is that she will get hurt. He will cheat. He was cheating on his girlfriend with the A list actress so you know that will continue.
