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.
