'Lizzie McGuire' was my big thing when I was younger. I did buy some pencils and back-to-school stuff of hers because she was on it. I loved her.

'Battlefield' was one of those slow-building songs, the way 'Tattoo' was. It was kind of a word-of-mouth hit. The more people heard it, the more they started requesting it on the radio.

Any extra free time you have, you are sleeping, or you're trying to sleep

I am not a sample size, and I am okay with that. I'm good with who I am. I like to accentuate the positive. My waist is something I love to show off. I'm also happy that more and more women are embracing who they are, because everybody's different. You don't have to be a size 0 to be pretty. You just have to be comfortable with who you are.

I used to eat because food tastes so good. I love food, it's one of the best things on this planet. But I changed the way I was thinking. I started asking myself, 'Hey, am I eating because it tastes good? Or because I really need some more? Am I really still hungry?'

If I eat something a little crazy or if I feel sluggish, I know I have to eat better the next day and work out. I work out, I do circuit training so I try to keep my heart rate up whether I'm doing cardio, lifting weights or jumping rope. I like to mix it up. I also take Zumba classes - I love those, those are a blast.

Being on 'Idol,' you have no choice but to be an open book.
