Hilary Duff dishes on Lindsay Lohan, Miley Cyrus and Avril Lavigne

Despite being in show business for nearly a decade, Hilary Duff has never gotten used to hanging with her fellow celebutantes.

"It's hard to find people who don't feel like they're in competition with you," she tells the May issue of Allure magazine.

But while she may try and stay away from her Hollywood peers, Duff, 20, couldn't resist dishing about Lindsay Lohan, Miley Cyrus and Avril Lavigne:

On Lindsay Lohan, she said, "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, she said, "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, she said,"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."
