The spin continues over what led Justin Timberlake and Jessica Biel to stick a fork in their four-year relationship, with speculation mostly centering on accusations that the crooner had a wandering eye and/or was infatuated with Mila Kunis. Now, Camp Biel offers an alternate scenario, one that has the actress as the dumper, not the dumpee. In this version, courtesy of the New York Post, the romance fizzled earlier this month during a getaway gone wrong at a Colorado ski resort to celebrate Jessica's 29th birthday. "Jessica has been telling friends they had an argument," says a source. "She told Justin, 'I'm tired of this,' broke it off and flew home to L.A. alone on March 7."
