Mary-Kate Olsen was working in show business when she was just a tiny tot. Now the megamogul and one-half of the Olsen twins has staked her claim in TV, film, video, fashion and even home decor! Mary-Kate is on the cover of Elle magazine this month, where she talks about everything from her sister to her celebrity status.

"It's weird to be called a celebrity," she says. "I mean, if I see a paparazzi shot of me walking that's in a magazine or something at some event, it's as if I see it from an outsider's point of view. There's like a character, almost, and then there's me. I think it's kind of entertaining."

As for her differences with her sister Ashley, Mary-Kate admits they don't always see eye-to-eye, but their bond is deep. "Unless you're a twin, you honestly can't know how close twins can be," she explains. "When there's that much love there's ... well, there's the opposite of everything, but it stems from love, and it stems from passion. We're driven people."
