Big Sean took to Twitter to warn Bieber to stay away from his girl saying, "This kid is about to learn not to touch my girl like that. Beliebe that," the message read. Big Sean has since deleted the post and there's no word on any drama between the two guys.

Beliebers immediately rushed to Bieber's side and they believe that their interaction was just a part of the show and shouldn't be taken out of context.
