Justin Bieber and Seth Rogen Feud: Singer Responds to Rogen's Diss- 'Sorry I Didn't Bow Down to You'

The Seth Rogen/Justin Bieber feud looks like it could just be one sided.

Bieber took to his Twitter to respond to the public bashing that Seth Rogen gave him while he was on the Howard Stern show promoting his newest flick Neighbors.

The singer tweeted, "Seth Rogan sorry I didn't bow down when I ask 2 meet u was probably a bit shy and didn't want to be over the top but still. Love ur movies."

During his time on the Howard Stern Show, Rogen reminisced about the first time the two met backstage of a German talk show. He told Stern that the Biebs requested a meeting with him. Rogen recalled Justin acting like he was "too cool for school," and he told Stern that he remembered 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 recalled 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 told 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."

While on the Today Show on Wednesday morning, Rogen told cohost Matt Lauer that it would be weird if he liked Justin Bieber.

"To me, the idea that, like, a grown man doesn't like Justin Bieber is not a controversial thought. Why would I (like him)? It would be much weirder if I did like Justin Bieber."

He then added fuel to the fire by saying, "I don't know anyone who likes Justin Bieber."
