Growing up "a little tomboy climbing trees" in Mount Clemens, Mich., Adrienne Frantz says she hated it when adults complimented her on her lush eyelashes—so one day she snipped them off. "My mom cried," she recalls.

Frantz, 23, still knows how to get a rise out of people. As the scheming Ambrosia "Amber" Moore on CBS's The Bold and the Beautiful since 1997, she has been busted for marijuana possession, has married an underage boy she once babysat and has even stolen her cousin's child. For such relentless nefariousness, Frantz took home a Daytime Emmy in May for outstanding younger actress.

But she also takes a prize for keeping busy offscreen. "I never stop," she says. "I go, go, go." Besides appearing in Speedway Junky, an indie film out this month, she's shopping an album of her classic-rock-inspired songs, working on a screenplay and giving dinner parties for 30 at the L.A. home she shares with her mother, Vicki, 45, a psychologist who is divorced from Frantz's father, John, 50, a landscaper. "I always find excuses to throw parties," says Frantz, citing her three-days-before-St. Patrick's Day bash last spring.

And she still finds time to date Johnny Rzeznik, 35, lead singer of the Goo Goo Dolls. "He's a good balance for her," says B&B costar Susan Flannery. "He seems able to calm and reassure her." Which she likely needed, after being attacked by an obsessed female fan at a press event last September. She remains undaunted, however, and hyperactive. "I just can't sit in a room and watch TV," says Frantz. "I'm also doing needlepoint or painting or writing songs." She laughs. "I need a vacation."
