Ellen DeGeneres is great at scaring the guests on her show. She scares them backstage, in their dressing rooms, in the bathroom ... basically everywhere. But this time she decided to execute her latest prank on her actual show in front of her audience. Her target? Justin Bieber.
Biebs was talking to Ellen about us upcoming Comedy Central Roast and talked about whether or not he's nervous or scared about what's about to come. But Justin was scared be something else: a guy who looks just like him jumping out of a box next to his chair! And did we mention the doppelganger was wearing nothing but underwear?
