#7 - Christina Aguilera
Speaking of stars that have never needed autotune... The one thing that has always separated Christina Aguilera from her fellow pop tarts is her amazing voice. She can belt it out like no other lady in music today. Gaga, Perry, Spears... all fail miraculously when compared to the original dirrty girl. Beyonce comes close, but not close enough to crack this countdown. It's because of her voice that it pains me to watch how bad Xtina's done this year. But it's also because of her voice that I know she'll rise to the top once more. Never underestimate the power of Christina Aguilera!
