I can't believe you used to date DiCaprio, now get back in the kitchen make my chicken soup with matzah balls.
If you read a gossip site like blindgossip.com you will find that actors and actresses make relationship agreements. They go thru the motions for the press while ahem.. pursuing their real likes. They specify a time limit then you read about the breakup. Rinse and repeat. Leo and George Clooney make such agreements. Women like Bar Refaeli do this because they become well known and make lots of money.
