Bristol Palin may be a polarizing figure in pop culture, but she's found an unlikely fan in filthy comedian Sarah Silverman!

Sarah told X17online that she was "excited" to see Bristol on Dancing with the Stars. "My secret hope is that she gets influenced by the people around her ... that Margaret Cho gets a hold of her and gets in her brain a little."

But even though Sarah may not be a fan of her politics, Sarah says "Bristol's a nice girl. I'm rooting for her!"
