Seth Rogen Calls Justin Bieber a "Piece of Sh**"—Again

By now we've all seen Justin Bieber's crazy deposition video, right? Well his latest stunt was the perfect fodder for Andy Cohen to bring up on his late night show Watch What Happens Live, since his guest Seth Rogen, has been so vocal about his thoughts on Beibs in the past.

While promoting their new movie Neighbors at South by Southwest, Rogen and co-star Dave Franco stopped by WWHL's temporary digs in Austin to chat about the film, compare the sizes of their.. um.. members and of course, talk about Bieber. When Andy brought up Rogen's now infamous tweet, Rogen defended it saying, “He’s obnoxious, ungrateful, and insincere and he puts people’s lives at danger with his horrible, horrible behavior. And, overall, he acts like a piece of sh**.”

So there you have it! Good luck making a cameo in Rogen's next Blockbuster, Biebs.
