Host Announced for Justin Bieber Roast

Justin Bieber's Comedy Central Roast just got some star power.

Kevin Hart has signed on to host the special. The Wedding Ringer star says, "I don't normally do roasts, but I had to step out for my guy Biebs. It's his big 21. It’s about to be operation roast everyone's butt." Hart may go easy on the bad-boy singer as they've been buddies for a while. The roast will be taped on March 14th and air on March 30th on Comedy Central.
