Comics Give Justin Bieber The 'Whuppin' His Parents Never Did At Comedy Central Roast

Justin Bieber’s mom was there for his Comedy Central roasting.

INSIDE EDITION asked her, "Are you nervous for Justin?"

She replied, "Yes!"

Kevin Hart said before the show, "Nothing's off limits. It's a roast. You hit everywhere."

Hart was good to his word before he took to the stage in Los Angeles when he said, “Tonight we're going to do what his parents and the legal system should have done a long time ago. We're about to give this boy an [expletive] whuppin he deserves!"

Funny man Jeff Ross didn't mince words, saying, "The roast fans really want blood this time. Because face it Biebs, you've become a cocky little (blank)."

Also on hand for the roast were Martin Short, Snoop Dogg, Shaquille O'Neal and Andy Dick.

Justin took his medicine like a man, admitting he's made some dumb mistakes: "I want to be able to laugh at myself at the end of the day."

Apparently, the roasting didn't hurt The Bieb. On a private jet ride later to Las Vegas, he was singing and dancing up a storm as he celebrated his 21st birthday in style!
