2. Katharine Mcphee
I can seriously go on and on about how underrated Katharine McPhee is. Not only is she an incredible singer, she's also an incredible actress! I absolutely LOVED her in NBC's Smash and have no shame in saying I bawled like a baby when I found out the show had been canceled. LOL. Now, she's gracing the silver screen again with a role on CBS' Scorpion. She's really fantastic and I don't think people give her the attention she deserves!
