In case you didn't hear, newly 21-year-old Justin Bieber is getting roasted soon, and apparently he really, really, really wants Seth Rogen to be there. The frequently shirtless singer has been sending Rogen tweets basically begging him to be there. NEWS: Here's everything Comedy Central Should Roast Justin Bieber About He's tried calling:@Sethrogen come on man. Check your voicemail. I took it like a man as u blasted a nervous kid fan of yours (me). Now I'm a man. Roast me!— Justin Bieber (@justinbieber) March 2, 2015 Laying on a little guilt: Starting a hashtag campaign: Bieber even tried throwing some jokes at Rogen's highly-controversial movie, The Interview, to try and get him to reply:Seth Rogen is no stranger to the Comedy Central Roasts, as he was actually the Roastmaster for his buddy James Franco.
