'Neighbors' Star Seth Rogen Comes for Justin Bieber- Proclaims 'He's a Bit of a D--k'

It doesn't seem like Justin Bieber and Seth Rogen will be friends anytime soon.

The comedian who has been outspoken about his dislike for the singer opened up to Howard Stern during his radio show on why he hates the Biebs so much.

Rogen reminisces about the first time the two met backstage of a German talk show. He tells Stern that the Biebs requested a meeting with him. Rogen recalls Justin acting like he was "too cool for school," and he tells Stern that he remembers thinking "I don't want to meet you! Don't act as nonplussed to meet me. I didn't want to meet you. I was totally cool with not meeting you."

A meeting, that after which, promoted Rogen to public proclaimed his dislike for Justin on Twitter, tweeting "All jokes aside, Justin Bieber is a piece of s--t."

Rogen recalls another miserable encounter with the singer during an award show. "I saw him again at like an MTV awards show, he literally had a snake wrapped around his wrist that he was wearing. Like a live snake as an accoutrement. I was like, 'What the f--k?' I talked to him for like five minutes. I just remember thinking, 'F--k this kid. He's a bit of a d--k."

Rogen tells the radio host that Bieber fulfilled all of the preconceived notions he had about the singer.

"He's a good example of someone who you meet who you think you are going to hate and then you get to hate him as much as you [thought]... You meet him and he lives up to every one of your expectations of how you hope he'll be."
