"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."
Levi has a long history of popping up in places where the Palins don't want him, including a trip to their hometown of Wasilla with comedian Kathy Griffin and her reality show camera crew.
"I wouldn't put it past him to try and sneak into a taping," an insider tells me. "The only person that loves the press more than the Palins is Levi himself."
Bristol, who shares custody of son Tripp with Levi, will be living in Los Angeles with her baby once the show goes live each week. Her mom, Sarah, is expected to be spending time with them and visiting the ballroom to cheer her daughter on.
"Security is very tight at 'Dancing With the Stars,'" an ABC executive tells me. "If someone is not wanted in the ballroom, I can assure you they will not get in."
