You know her as Blair Waldorf, but Leighton Meester is also breaking into the movie business, and following in the footsteps of Lauren Conrad and other TV stars by launching a fashion line!

Here's Leighton's interview with Nylon Magazine ...

Nylon: In Remember the Daze, you worked with a director who was your age. How was that?

Leighton Meester: It was awesome! She is young, but very, very smart. Jess made the set a little more casual and fun; it was less like work. Definitely the most fun work I've done, ever.

Nylon: You were blonde in the movie ...

Leighton Meester: I was blonde in general, not just for the movie. I mean, for a while I just was blonde. And I guess it's hard for people to see me as a different character [than Blair Waldorf] but the whole thing was a different experience and a different kind of movie. It's coming of age, it doesn't talk down to the audience and it's an experience more than anything.

Nylon: It's about high school kids in 1999 ... you were in high school in 1999... any similarities?

Leighton Meester: Not really. I went to Beverly Hills High - yeah, I really did. I guess I was kind of friends with everybody and NOT popular. But in this movie, there are much higher stakes than in normal high school.

Nylon: Were you a model in high school? My friend swears you used to walk on the runways during New York and L.A. Fashion Week.

Leighton Meester: It definitely wasn't me! No way! No way, no way, and I don't think I would ever do something like that in the future.

Nylon: What about designing? Do you think you might want to try having your own clothing line?

Leighton Meester: Absolutely. I would love to do my own thing, and see where that could take me. I love fashion, and sometimes I just feel like if I could only do and make whatever I wanted, it would make so much of a statement and really express who I am. So yes, in the future I would love to do a clothing label or work with a clothing label.

Nylon: Any designers you'd want to work with?

Leighton Meester: I love Missoni and DVF, I've heard she's an incredible woman and I'm dying to meet her. And I like Miu Miu, Alberta Ferreti, and you know, I really love Julie Haus.

Nylon: Give us some advice: How should someone start being an actor?

Leighton Meester: There's no right way of getting into it. I didn't grow up in a Hollywood family, I mean, I'm from Florida, but I knew that it's what I wanted to do. I met a manager and he said, come to New York and try auditioning. So that's how I did it, but you could do anything - do it in college, be in plays. And just experience everything, don't doubt yourself, and don't lose sight of what you're really trying to be an actor for, and hopefully it's the right reasons - because you're inspired, and you love it, and you have a good head on your shoulders. Don't try to be anything but yourself, and find success as yourself, you know? Otherwise, you won't be happy.

Nylon: Give us some more advice: If someone sees you on the street, what should they do? Say hi?

Leighton Meester: Of course! Go for it! I mean, I'm not gonna like run away or anything!
