Billy and Alison, Melrose Place's cutest couple, have been on the outs for much of this season, to the delight of Courtney Thorne-Smith. "When Billy and Alison get together, they're annoying and self-centered," says Thorne-Smith, 27, who plays Alison. Her real-life romance with Andrew Shue, Melrose's Billy, was more satisfying, although they, too, split after a year. "We were two nice kids under this incredible stress," she says of the first, frantic Melrose days. "I don't know if I could have gotten through it without him. We had a light, fun, sweet relationship. We'll always have a close bond." So they're comfortable now just being good buddies? "Ask me when one of us gets married," she says. "That'll be hard."
