Seth Rogen is not a Belieber.

According to Digital Spy, while talking to Howard Stern on Sirius Monday, the Neighbors star explained that he’d met the young pop star a few times. “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… you meet him and he lives up to every one of your expectations,” Rogen said.

According to Rogen, he first encountered Bieber backstage at a German talk show. “Someone came to the door and was like, ‘Justin Bieber wants to meet you,'” Rogen said. Apparently, the actual meet-and-greet didn’t go as expected. Rogen said Bieber acted as if Rogen had wanted to meet him. “What the f—, I don’t want to meet you! Don’t act all nonplussed to meet me. I didn’t want to meet you,” Rogen said. “I was like, ‘He’s a little bit of a motherf—er. Whatever. He’s a bit of a d—.'”

And their next meeting didn’t exactly redeem the Biebs. “I saw him again at like an MTV awards show, he literally had a snake wrapped around his f–king wrist that he was wearing. I talked to him for like five minutes… No humility, no awareness, no sense that ‘I appeal to young, young people, maybe a grown man who works in comedy doesn’t f—ing give a sh– about me. Maybe I should act in such a way that perhaps this isn’t the great experience of his f—ing life.'”

Rogen’s final thought: “I remember thinking ‘He’s a piece of sh–.'”

And with that, Rogen officially joins Jon Hamm — who called Bieber a “s—head” in Men’s Fitness — in what I like to call the “Grown Men Who Hate Justin Bieber Club.” Who will be next to join? Perhaps Bieber will grow up a bit and learn to hate his former self? Hey, a girl can dream.
