The rock rebel talks to Star about her new album, attitude and eating habits. Dig in!

Canadian-born pop singer Avril Lavigne, 19, follows up her 2002 debut album, Let Go---which sold 14 million copies----with UMS. The introspective album showcases a more feminine and mature Avril, who co-wrote the songs. Star caught up with the punk princess before her May 24 concert, which was broadcast live on AOL for Broadband, at New York City's Webster Hall.

Q: What gets under your skin?
Av: What's under my skin? Bones---ha ha! My friend came up with that.

Q: Do you feel different in a skirt vs pants and a tie?
Av: When I wear a skirt, I feel older, more sophisticated. I'm always crossing my legs and when I'm not, I'm [slouches]. Most of the time, I just want to be comfortable, but I'm a chick, and I feel like wearing skirts every once in a while.

Q: Say something positive about Britney Spears.
Av: I've totally lost respect for her, and I think a lot of people have. She's gone too far. Something positive that I can say bout Britney? I think she's probably a really strong person, because she's had to go through a lot. Trust me, it's extremely difficult to have people judging you.

Q: So you're on a new low-sugar diet?
Av: I have huge mood swings, so I'm totally healthy now and I feel a lot better. I was eating really badly. I'd be drinking beer every night, eating mozzarella sticks and chips and drinking pop all the time. I felt like crap, so I decided to be healthy now. If I drink a glass of orange juice, I'm like this [feigns being lethargic]. But I have my moments when I have McDonald's. I can't have coffee. It's sooo bad for you; its just artificial. And I'm not calling myself a hardcore vegetarian, but I stopped eating most meat.

Q: Your new song "Don't Tell Me" is pro-abstinence.
Av: It's basically about having respect for yourself and being able to say no. I mean, so many guys try to pressure girls into doing it. Because, I think, 70% or 80% of girls who've had sex didn't want to. Girls are going through that at a younger age now.

Q: Do you see yourself as a role model?
A: I'm not trying to be. I don't like to be. It's just that for some people, I am.
