The starlet, 25, might be ready to poke fun at her dissolute reputation, but she tells Matt Lauer in a Today interview airing Thursday that she's no longer the girl gone wild that she used to be -- especially when it comes to late-night partying.
"I went out, actually, a few months ago with a friend. And I was so uncomfortable," the Mean Girls star tells Lauer. "Not because I felt tempted, just because it was just the same thing that it always was before. And it just wasn't fun for me. I've become more of a homebody. And I like that."
Lohan's ongoing legal problems and substance abuse struggles have been thoroughly covered in the press, and Lohan doesn't try to shy away from those issues. She tells Lauer she's now "clean and sober," but admits, "I still need to go through the process of proving myself."
"We start production soon," Lohan says. "I've been doing tons of research. But I've always kind of researched her. She's always been a fascinating woman to me. So I'm really honored. And I will not let anyone down, especially myself."
Lohan is particularly appreciative of the role, because she recognizes how difficult it is for filmmakers to even get her insured on a project.
"I could see where it could be scary for people to invest in me," she says. "And I don't want people to have that reason to be scared anymore. So being able to have this opportunity with SNL and the film, I'm gonna do what I'm supposed to do, and enjoy doing it, and do it as best as I can."
