Lindsay Lohan doesn't want to be called a Teen Queen. In an interview in the March issue of Allure magazine, now on newsstands, the 19-year-old says she wants to be considered a serious actress — and rejects her youthful, party-girl image.

"I hate it when people call me a teen queen," Lohan says in an interview.

Lohan, star of family friendly movies such as "Freaky Friday" and "Herbie: Fully Loaded," has recently graduated to more grown-up roles, acting opposite Meryl Streep, Lily Tomlin and Tommy Lee Jones in Robert Altman's "A Prairie Home Companion," due in theaters in June.

She's also been working on "Chapter 27," a film about the death of John Lennon, starring Jared Leto.

As for her days as a Skinny Girl, Lohan says: "Sometimes being that thin doesn't look healthy. I kind of didn't realize that."

She dropped pounds from her shapely figure following a hospital visit last year, she says. "I lost weight when I was in the hospital, and then I wanted to keep it off."

"It was an attention thing, too," she adds. "(But) you start to wonder if your friends are your friends because you look a certain way."

Regarding her breakup with Wilmer Valderrama, Lohan tells the magazine: "I know now that I don't need a boyfriend."

The past year "felt like five lifetimes because I've grown up a lot," she says. "I know better what to do and what not to do. I lost sight of the people and things that are most important to me."
