As previously reported, Justin Bieber has signed himself up to be roasted on Comedy Central for his 21st birthday. Following more than a year of shenanigans, Bieber decided to own up to all the things that have made him seem like a d-bag. Now Comedy Central and emcee Kevin Hart have announced who will roast the Canadian crooner. Hannibal Buress, Chris D'Elia, Snoop Dogg, Natasha Leggero, Ludacris, Shaquille O'Neal, Jeffrey Ross, and even Martha Stewart have all signed up to bring the heat. However, one name is missing from the roasting roster: Seth Rogen.

Last month, Bieber petitioned his fellow Canadian to roast him on the show. Now that the lineup has been revealed, the Biebs has voiced his disappointment of Rogen's absence.

"@ComedyCentral @KevinHart4real that's cool. But someone is missing. Don't fail me now@Sethrogen!!!" he wrote on Twitter, adding the now-trending hashtag. "#whereisseth."

Bieber's beef with Rogen goes back to January 2014 when he expressed his hatred for the singer on Twitter by posting, "All jokes aside, Justin Bieber is a piece of s--t."

There is still time for Rogen to sign on. Or maybe he already has, and it's just going to be a surprise. Time will tell, but the roast really wouldn't be complete without him.

Leading up to the roast, Comedy Central has posted two trailers. The first featured a shirtless Bieber getting pelted with eggs and the most recent spoofed his Calvin Klein commercial with Ross dressed as the female model (a.k.a. his worst nightmare).

Bieber recently spoke about his decision to be roasted in an appearance on Ellen.

"I think it's just cool to like be able to laugh at yourself, you know," he told Ellen Degeneres, who refused to be a part of the roast when asked by Scooter Braun. "I've done some things that might not have been the greatest. I just want to be able to laugh about it and kind of just own up to some of the things."

Tune in March 30 at 10 p.m. EST to watch Bieber face the music.
