Seth Rogen has been pretty blatant when it comes to his dislike for pop star Justin Bieber. The Knocked Up star has slammed Justin Bieber once again, calling him a “piece of s--t” for the second time.

On Bravo’s Watch What Happens Live last night, Andy Cohen asked Rogen to explain his tweet calling Bieber a “piece of s--t” from back in January shortly after the As Long As You Love Me singer got arrested for a DUI, reports USA Today.

“In my opinion, Justin Bieber is a piece of s--t,” Rogen re-iterated. “He seems like he's obnoxious and ungrateful, insincere, and he puts people's lives at danger.”

Rogen also spoke to Cohen about famous co-stars that he’s smoked weed with, in a skit called “Spill The Herbal Tea”, according to E! Online.

“This is really depressing for me to say…I've never smoked weed with James Franco because he doesn't smoke weed. That's why he's such a good actor!” he dished about his longtime friend.

However, his list did include the likes of Sarah Silverman, Paul Rudd, Snoop Dogg, and Jonah Hill.

It seems safe to say Justin Bieber won’t be joining that list anytime soon.
