Recently I found a meme about a plan a girl had to put a group of young girls together in a place where Justin Bieber was to soon arrive and have them act as if they don't know him. Just to see his reaction. He would probably cry. Seth Rogen can agree that the Biebs is just a little full of himself.

During a Howard Stern XM radio interview, the 32-year old "Neighbors" star held nothing back while discussing Justin Bieber. "I've met him a few times. He's a good example of someone who you met 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" Rogen told Stern.

The comedian also added that the first time he met Bieber was backstage at a German talk show, where Bieber specifically requested a meeting with the actor. According to the "This is the End" star, once the two were introduced, Bieber made it seem like Rogen was the one who asked for the meeting. "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. I was totally cool with not meeting you," Rogen says. "He's a little bit of a mother-f*****. Whatever. He's a bit of a dick."

Unfortunately, this isn't something we are surprised to hear as the "Confident" singer has been described to be a bit arrogant. You would think it would be a friendly encounter between the two Canadian stars, one being such a funny man, but these two don't really "get each other." The "Freaks and Geeks" star, however, did not end his rant there, also describing another time he ran into Bieber at an MTV awards show. "He literally had a snake wrapped around his f**king wrist that he was wearing, like a live snake as an accouterment," he started. "I was like 'what the f***?' I talked to him for like five minutes. I just remember thinking, 'F*** this kid.' I remember thinking, 'He's a piece of sh**.'"

Rogen goes on to compare Bieber to Zac Efron, and how Efron actually turned out to be really cool. "When I met Zac Efron one of the most endearing things is that he recognized, that as a Disney star -- or I as a man in my late 20s/early 30s, would f**king hate him. Because why wouldn't I? ... Justin Bieber had zero f***king percent of that."

Well, Bieber probably won't be having Seth Rogen in his next music video.
