Actress Hilary Duff grew up on the Disney Channel as the lead role in the show "Lizzie McGuire," before going on to become a film star and pop singer. Despite being in show business for most of her life, the star still doesn't feel comfortable with competition from her fellow celebrities.

She talks about her competition, and her desire not to be mixed up in it, in the May issue of Allure. Duff, 20, also appears on the cover of the magazine.

Duff dished to Allure about her peers, including Lindsay Lohan, Miley Cyrus and Avril Lavigne:

On Lindsay Lohan: "Supposedly, I stole Lindsay Lohan's boyfriend [Aaron Carter.] We were, like, 13! And I've never stolen anyone's boyfriend! I don't know how you do that! . . . She was talking about it and I wasn't. It made us both look bad and put up a big weirdness. Really she was just a girl my age. We are fine now, by the way."

On Miley Cyrus: "We don't have each other's phone numbers. But when she meets me, she's excited. It's cute - I see a lot of myself in her."

On Avril Lavigne: "I said something about how she didn't like her fans dressing like her, and how she should appreciate that because it's a compliment. She called me a goody-goody [Lavigne called Duff a 'mommy's girl' in Newsweek] Everyone is trying to prove who they are, and their position. So, I'm 'the good girl.' She's 'the bad girl' or 'the party girl.' Sarah Jessica Parker doesn't take her clothes off, but she's not a 'good girl.' [Adult actors] don't get tagged like we do."
