"@Sethrogen all I want for my birthday is for you to roast me. I took the twitter bashing please make my bday and do it in person. Thanks," Justin wrote Thursday night on Twitter.
He also made light of Seth's Interview Sony email hack when he followed up with another tweet that said, "@Sethrogen I would have emailed u but this is the only electronic communication with u that doesn't scare me. Hope to see u at the roast :)."
While that might seem like a pretty awesome, open invitation to hate on the Biebs, Seth might be hesitant to take the gig. He's not a big fan of Justin at all. Last year he ripped the pop star a new one, after meeting him backstage at a TV show.
"[Justin's] a good example of someone you meet, who you think you're going to hate, and then you get to hate him as much as you thought," Seth said about the Biebs. "You meet him, and he lives up to every one of your expectations of how you hope he will be."
Seth went on, dissing Justin by referring to him as a "d**k" and "motherf**ker." He ended his rant by making sure everyone knew his feelings by posting on Twitter, "All jokes aside, Justin Bieber is a piece of s**t."
So, do you think Seth will join Kevin Hart and roast the Biebs? Think he should?
