Rising Star Emilie de Ravin

One thing that makes Emilie so perfect for the role of Roswell alien Tess Harding is that she knows what it's like to feel alienated. "I went to ballet school in Australia, and it was the bitchiest atmosphere," she says. "I think it happens to every girl in every country: You think a girl's your friend, and then she goes behind your back and tells stories about you. Well, I was nice to everyone. I knew that I didn't want to be like those other girls!"

Emilie's two sisters helped her through the hard times while she was growing up. "They're much older than me--I'm 18; they're in their thirties--so if I was ever embarrassed about something, I could go to them for advice," she says. "I remember when I was 14, I had a crush on this guy and asked one of my sisters what to do. She was like, 'First, you don't want to be too pushy with him. Make him come to you.'"

Emilie took her sister's advice a little too far. "When my crush finally asked me if I wanted to go to a movie with him, I tried to act all cool. I was like, 'Not tonight--I have other things to do,'" she says, laughing. "When my sister found out, she was like, 'You don't want to totally brush him off!' So I had to call him back and say, 'Actually, I really don't have anything to do tonight. So ya know, if you were still planning on going to see a movie, I could still go with you.'" The moral of the story? Even aliens can be down to earth!
