Jeffrey Ross Replaces Lara Stone In This Hilarious New 'Roast of Justin Bieber' Promo: Watch

'I'm your worst nightmare,' says comedian.

Get ready, Beliebers: the Comedy Central “Roast of Justin Bieber” is coming your way in just a few weeks.

And just in case you didn't think they were bringing the LOLs, the network's latest promo should ease all fears.

In the brief black-and-white clip, which parodies the “All That Matters” singer’s Calvin Klein commercial, a pot-bellied dude wearing a blonde wig (definitely not Lara Stone) gets a little too close to the Biebs after his drum solo.

“I want you, Justin,” says Roastmaster General Jeffrey Ross. “I wanna stick my pinky in your a--hole. I’m a Belieber.”

Totally hot.

“Who is this guy?” Bieber asks.

“Hey, Man, I’m your worst nightmare,” Ross replies.

Come the end of this month, this very well might be true. We definitely can't wait to see what insults are thrown at the Biebs when "The Roast Of Justin Bieber" airs on Comedy Central March 30 at 10/9c.
