Charmed! Holly is great on Pretty Little Liars but she originally won our love as the witch Piper on this WB classic.
When she was on Charmed, she was only cast member that appeared on every episode of the series' eight season run. Can you say hard-working?
Picket Fences. Holly may have made us fall in love with her as Piper, but her first big TV role on quirky family classic Picket Fences is also great.
She's sassy. Back when she audition for Picket Fences the casting director told her "she didn't have a big enough heart." She retorted, "If you're looking for someone with a big heart, what the hell are you doing in New York?” Love it!
