I didn't think Norah Jones was an actress and then I saw her performance in My Blueberry Nights and I realized I was right- she's NOT an actress.
Here's are 10 other singers that should NEVER EVER act again:
2 Huey Lewis
4 Whitney Houston
6 Jessica Simpson
8 Mariah Carey
10 Britney Spears
p.s. I'm not completely heartless to failures that make an effort so if these actor-wanna-bees really want to get it right then they should take Acting 101 from the AMAZING Dolly Parton.
