Zac Efron would make us feel guilty for eating big dinners. He'd say, 'Do you really want to eat those carbs?' It was like, 'Thanks a lot!'

You can feel like, 'I look really bad', but to other people you can be really gorgeous.

For me, I just like to cut out bread. I like to keep the good carbs in my diet - I love pasta and Italian food - but I try to eat just that on the weekends and cut out carbs during the week.

Zac Efron is like a brother who's just goofy and crazy. He plays a lot of practical jokes.

If I feel like someone's trying to bring me down, I just walk away from it.

I wrote a song with Kara DioGuardi called 'What If,' and it's a really beautiful song. It's kind of like a rock ballad. There's a lot of guitars and drums in it.
