25. HEATHER LOCKLEAR
If playing a likable bitch is an art, then Locklear is TV's Sistine Chapel. But prettier. Her California-girl looks may have caught Aaron Spelling's eye, but it was the actress underneath who made her the producer's go-to player in the '80s (see: Dynasty's Sammy Jo; T.J. Hooker's Stacy). So when Melrose Place needed a jolt of charisma, Spelling knew who to call: As blond ballbuster Amanda, Locklear not only saved the show, she became prime time's most sought-after problem solver (see: her next gig, Spin City).
