My mum says, 'Go with your first instinct,' but this can lead to impulse buying!

It's so weird that I went to rehab. I always said that I would die before I went to rehab. But I thought, 'I'm going to stay here tonight.' And I stayed there for a month. It was great.

Girls my age dress so much raunchier than I'd ever imagine myself dressing. I understand that I'm a role model, though, and I have to look out for that. I have a 10-year-old sister, too. But you also want to be appealing to guys and stuff, that's just something girls feel. It's hard. You want to be that girl that's unattainable to all the guys because there are so many other girls out there that are like that.

I want to give back. I want to do all the things that will make me feel fulfilled. But whenever I do those things, people think it's a press stunt or something.

I would switch roles with Madonna for a day. Or if Audrey Hepburn was still alive, Audrey Hepburn. I love Audrey Hepburn. She's one of my idols also.

Everyone has highs and lows that they have to learn from, but every morning I start off with a good head on my shoulders, saying to myself, 'It's going to be a good day!'.

I am happy being able to play roles with people my age because once you do something really mature there is no turning back.
