As an actor, I really like Philip Seymour Hoffman. I think he's a genius.

I have always hated celebrities lecturing people on politics.

I don't want to tell a 15 or 14 year old what they should be doing. I want them to tell me. And that's what I got when I met Justin Bieber for the first time.

I was slightly cynical of the American mentality before I came over here, but now I preach it. Here, no one's going to tear you down if you buy yourself a $300,000 car. They're likely to say: "Well, you probably worked hard for it. Good luck to you."

Most things in music go full circle eventually.

My dad wasn't someone who was a great disciplinarian, we had a fun relationship, but he gave me really constructive advice in my life, which I still carry today and I do pass on to other people. So if I can have the same relationship with my son as I had with my dad, then I think he'll be very happy and I'll be very happy.

I don't like kids that are pushed into things by stage mums, but when I can see they are having a good time, they're excited and enjoying the process, then I think it's wrong to discriminate.
