Washington, May 6: Seth Rogen recently slammed Justin Bieber by saying that the popstar was "a little bit of a motherf-ker".
The 32-year-old stand-up Canadian told Howard Stern on XM radio show that he has met the 'Baby' hitmaker a few times and he is a good example of someone who one meets who they think they are going to hate, Huffington Post reported.
Rogen said that when the two of them were introduced, Bieber made it seem like Rogen was the one who asked for the meeting to take place and Rogen thought that the Canadian singer was "bit of a dick".
Rogen had earlier called Bieber "a piece of shit", when he appeared on Andy Cohen's show 'Watch What Happens Live'. (ANI)
