Meet the Cast of Hairspray

Nikki says ever since she saw Hairspray for the first time on Broadway when she was 15, she knew she wanted the role of Tracy. "Growing up, I was always happy, but this has just made me the happiest kid in America—I think in the world," she says.

With her newfound success, Nikki says she did one thing to pamper herself. "When I got home, I was so excited. I said, 'I have to do something for myself. I have to buy myself a new bed, because I've had the same bed for 18 years,'" she says.

The first time she walked onto the set, Nikki says she was extremely nervous to meet her famous co-stars—until she saw John Travolta. "I walked into a room and there he stood, and he said, 'Come to Mama!'" she says. "Then I knew it would be amazing."
