Wondering if Bristol Palin wants to see ex Levi Johnston staring from the audience when she takes the "Dancing with the Stars" stage?

Brace yourself. It turns out she doesn't. The fameball baby daddy, who was twice engaged to the Season 10 competitor, won't be welcome when the series starts September 20.

PopEater reports that Palin has already spoken with producers about banning Johnston from the set -- should he try to finagle his way into the crowd. And, let's be honest, he probably would.

"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 Palin family friend tells PopEater.
