LOS ANGELES- The phrase 'Justin Bieber has no idea what he's getting himself into' seemed to be what everyone was talking about at his Comedy Central Roast.

The pop star hit the white carpet, with his blonde hair and perfect purple (his fav color!) suit, to mingle with a crowd of screaming Beliebers, and he was feeling pretty "awesome."

And why shouldn't he? He's ready for the heat and will "return fire" with some material that's "real" to his heart.

But it is a roast, and a lot of his past mistakes will be thrown in his face, which leaves mama Bieber, Pattie Mallette, "just as nervous" as the Beliebers.

Justin will be taking the jabs from several comedians, like Roast Master Kevin Hart, plus his "Baby" collaborator, Ludacris, who warned Justin's fans that after they watch this show on Comedy Central on March 30 they may be just a little "pissed."

But it will all be OK, Justin -- just take some advice from your good friend, Snoop Dogg.
