EXCLUSIVE OUTTAKES: Justin Bieber's 'Fantasy Factory' Rampage

By
Justin Bieber's adolescence has been far from ordinary but he proved to be just one of the guys in this exclusive sneak peek of 'Rob Dyrdek's Fantasy Factory.'
Boxing, hooping and talking trash, the teen heartthrob went on a rampage inside Dyrdek's famous warehouse.
"I was trying to inspire [Bieber] to be like, 'You gotta be crazy,"' said Dyrdek. But the Biebs needed little instruction as shown in our exclusive clip of this never-before-seen footage.
Watch the entire episode dedicated to show outtakes when it airs on Monday at 10:30 PM ET/PT on MTV.
