I love it when people say things to me in public and want to meet me, because I want to meet them! Early on, my manager told me, 'If you want to sell 500,000 records, then go out there and meet 500,000 people.'

We were four guys... I met Paul, and said, 'You want to join me band?' Then George joined and then Ringo joined. We were just a band that made it very, very, big, that's all. Our best work was never recorded.

That was a great period. We were like kings of the jungle then, and we were very close to the Stones.... I spent a lot of time with them, and it was great.

It's about you putting in the work, practicing every day, and hopefully one day you write the song the whole world wants to get down to. And one day you're going to be sitting next to Ellen DeGeneres talking about how you broke records and rocked the Super Bowl!

I don't care what people say about my relationship; I don't care what they say about my boobs. People are buying my songs; I have a sold-out tour. I'm getting incredible feedback from my music.

For some people, fame kills it and becomes more important than the music or the performance. But for me fame is like rocket fuel. The more my fans like what I'm doing, the more I want to give back to them. And my passion is so strong I can't sleep - I haven't slept for three days.
