Justin Bieber continues feud with Seth Rogen claiming he was shy

Justin Bieber has finally responded to Seth Rogen's recent harsh remarks about him when Seth called him 'obnoxious'. 'ungrateful', insincere, and perhaps most damning of all, 'a piece of s***'.
The 20-year-old pop star tweeted: 'Seth Rogan (sic) sorry I didnt bow down when I asked 2 meet u was probably a bit shy and didn’t want to be over the top but still. love ur movies'.
The incident referred to is when Justin asked to met Seth while they were both on a European TV show. It's unclear whether Justin deliberately spelt Seth's last name wrongly in his tweet.

In a new interview with Howard Stern, Neighbors star Seth didn't mince words by saying, 'the kid's a d***' while adding, 'he's a good example of someone you meet, who you think you're going to hate him, and then you get to hate him as much as you thought,' reported Entertainment Tonight.

To the disbelief of Justin's teen fan base, Seth was not surprised by what he claims the controversial singer is really like.

Not a fan: Justin and Seth hung out at the 2011 MTV Video Music Awards in 2011 but did not hit it off

'You meet him, and he meets up to every one of your [bad] expectations of how you hope he will be.'

According to the 32-year-old actor it was Justin who first wanted to meet him while they were both appearing on a German TV show .

'So I went outside to meet him and he was acting like I asked to meet him! It was very nonchalant, 'Yo man. Sup,' and I'm like, 'What the f***, I don't want to meet you.'

Not too worries: Seth didn't seem to perturbed by Justin's response when he and wife Lauren Miller walked their dog in New York

The Baby singer's too cool for school attitude didn't sit well with Rogen.

'Don't act all nonplussed to meet me. I didn't want to meet you! I was totally cool not meeting you,' he recounted.

'But I was like, fine, I wouldn’t have said anything, I was like, 'Aye, he's a bit of a mother*cker. He's young, the kid's a d***.'

The two stars would meet up a few years later at an MTV Awards ceremony but unfortunately Justin would leave a similar impression again.

'He literally had a snake wrapped around his f***ing wrist that he was wearing. I was like, what the f***?' said Rogen.

Lashing out: The 32-year-old voiced his disdain for the pop star in a tweet back in January
