I saw him at the club and one of his friends was like, 'You're gonna meet Justin' and I just remember - everyone knows Justin Bieber, right? Everyone grew up, at least I grew up, listening to his music. I know all about him, I was so nervous.

Justin Bieber stole my haircut. And Axl Rose stole my dance!

I love to listen to pop all the time! I like to be updated on the new hits; I think it's important for what we do. Among my favorites of all time is, of course, Madonna. But I also love Kylie, our little princess; Beyonce, Bruno Mars, and Justin Bieber. And I listen to Italian pop music like Tiziano Ferro.

I'd like to work with Justin Bieber. He's talented and he's so young. I know what he's going through. I've lived what he's living through right now. Working with him would complete a circle of sorts for me. And he might find it a worthwhile experience himself.

I look at Justin Bieber and my heart breaks for him, because I know what he's going to go through. He knows it. Everybody knows it.

Artists like Justin Bieber or Lady Gaga have more sway over popular minds than a politician.

I was scrolling through my Twitter feed one day, and somebody had tweeted me a picture of Justin Bieber that had been Photoshopped with makeup or something. And I thought it was funny and so I hit retweet - I just retweeted a tweet - and all of a sudden, the remarks were coming in.

We even have a music career. Our song ‘Hold On,' charted on Billboard. I mean, we don't have aspirations to tour with Justin Bieber but we have a lot of different interests and talents.

I think YouTube has destroyed the genre barrier. People can be into Justin Bieber and Eminem at the same time. It's a good thing.
