Bristol Palin hasn't set foot on the 'Dancing With the Stars' ballroom dance stage and she is already demanding that her attention-starved ex-fiance, Levi Johnston, be barred from the audience.

"The last thing in the world Bristol wants is to look up from her cha-cha-cha and see his big goofy grin looking at her," a family friend tells me. "This is her time to shine and she doesn't want him trying to steal her spotlight."
