A source tells People magazine that Jennifer Lopez is over Casper Smart, 25. It's only a matter of time before she trades him in for someone else! Jen has always been extremely desperate and co-dependent.

A source says "Jennifer is the kind of girl who doesn't like to be alone. Until she finds a replacement, I think, he's around."

I hope Casper doesn't read this story. How's he supposed to take off his bumble bee costume and give it to Jenny when he reads this?

People magazine is reporting that JLo's people think that Casper's had it too easy.

"He's moved into her life – and a little too easily, too. I think her family is watching him closely."

Jen and Casper's rep threatened two tabloids for posting photos of Casper walking up the stairs of a gay spa in NYC. Marc Anthony tried to reconcile with Jennifer but she turned him down for Casper. I'm hoping that she's having a change of heart!
