Troubled pop star Justin Bieber has hit back at Seth Rogen after the actor blasted his behaviour during a radio interview.

The Knocked Up star has taken aim the singer on a numerous occasions, including in January when Rogen called him a "piece of s--t" on Twitter.com.

Speaking to radio DJ Howard Stern on Monday, Rogen defended his criticism, saying, "I met him a few times. He's a good example of someone who you meet, who you think you are going to hate, then you get to hate him. You meet him and he lives up to every one of your expectations."

Rogen recalled their first meeting backstage at a German talk show when Bieber requested to meet him but acted rudely when they were introduced.

The actor adds, "(I thought) 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 like, 'He's a little bit of a motherf---er. Whatever. He's a bit of a d---.'"

Bieber has now hit back at Rogen on Twitter, writing on Thursday, "Seth Rogan (sic) sorry I didn't bow down when I asked 2 (to) meet u (you) was probably a bit shy and didn't want to be over the top but still. Love ur (your) movies."
