TV's Underrated of 2008

Jessica Lowndes
"90210," The CW

You know her as: Former child star turned stressed out, overdosing high-schooler Adrianna

Why we like her: She had us hooked from the very first episode. We rooted for her completely out-of-control character to keep pushing the limit while always expecting that her time on the show would be cut way-too-short. Now she's on the straight-and-narrow, but we're secretly hoping boyfriend Navid's family business might tempt her to be led astray once again.

Where else you've seen her: Sorority sister and Rebecca Logan flunkie Mandi on "Greek"
