I've never liked the idea you have to be a certain age to be a pop star. I like the idea that anybody can enter, anybody can compete.

I was so tired, wasn't having fun any more, and wasn't sure if I wanted to do this any longer. So I turned my phone off and sorted my head out. It was the opposite of a breakdown really, it was a break-up - I got rid of all the idiots, realised my job was supposed to be fun, and got on with my life.

I get very anti-social, depressed and irritable with people. I don't have time for them. I can't make phone calls and stuff. I just sit on my own for days.

If I had to say who is the number-one most powerful figure is in reality TV, it's very easy. It is the general public. They're the only people who have power now.

Beyonce is good-looking. Jennifer Lopez is good-looking. Madonna used to be good-looking.

I don't mind being cast as some kind of a pantomime baddie, but I am very fair in business. I always have been. I pride myself on being fair.

You always want to go to a party where you get an invite.
