The beef boiled to the surface this summer after the two attended the New Jersey wedding of a Hollywood producer and kept their distance. Tongues immediately started wagging with a source telling Us Weekly, "Andrew hates that they're put in the same category because they're both English and around the same age. … Andrew considers himself 'a serious actor' and sees Rob as the equivalent of a cheesy boy bander because of 'Twilight.'" Ouch. But another source says it's not that serious. "Both like intense parts and go after the same roles. They're just naturally competitive."
