VIDEO : Justin Bieber, Seth Rogen Resolve Beef

Justin Bieber and Seth Rogen have officially ended their feud, more than a year after clashing on social media. The two Canadian stars came face-to-face recently while taping appearances on Ellen DeGeneres? show. On the show, Seth told Ellen he had made up with Bieber backstage. The ?Pineapple Express? star said, ?We had a beef, I guess you would say." Rogen then explained that it wasn't really a beef, it was that he'd called Bieber some really mean things on social media for no real reason. Rogen had met Bieber only once, and described it as a "very pleasant interaction." Among other things, Rogen has publicly called Bieber a d-word, a mother-f-word, and even a piece of s-word.
