Alright, now it's safe to start collecting on that office pool. Anonymous sources are telling People magazine that Jennifer Lopez and Ben Affleck have split although it's not clear if the break-up is permanent. People says Affleck dumped Lopez due to "second thoughts" about their impending wedding. Rumor has it Lopez's alleged request for a prenup may have contributed to Affleck's change of heart. Whatever the reason, J.Lo seems to be handling the estrangement like a woman who's been through this three times before. The New York tabs are running snapshots of the singer-actress frolicking in the Miami surf over the weekend. Affleck, meanwhile, was spotted gambling and sunning himself in Las Vegas. And me? I'm $20 richer.
