Bristol Palin might not be the best dancer in the world, but she thinks she has discovered a secret weapon that will help her win: Kate Gosselin.

"Kate became close with the Palin family when she taped an episode of her TLC reality show with Sarah Palin," a source tells me. "Since then, Bristol and Kate have become e-mail pals and Kate is happy to give her lots of dancing advice. Kate wishes she had had a mentor to help her through the tough contest and is happy to help Bristol."
