#17: Tiffani Thiessen as Valerie Malone
When Tiffani Thiessen joined Beverly Hills, 90210 as Valerie Malone, she instantly shook things up. Darker, edgier, and far more complicated than the wholesome characters before her, Valerie arrived from Buffalo with secrets and attitude — quickly becoming the show’s new wildcard.

Thiessen brought a sharp mix of confidence and vulnerability to Valerie. Beneath her manipulative surface was someone craving love and belonging. Fans either loved or hated her — sometimes both in the same episode — which is exactly why she was unforgettable.
