Bristol Palin has reportedly barred ex-fianci Levi Johnston from the sets of 'Dancing With the Stars'.

PopEater reported that Bristol has it made clear that she doesn't want her daughter's father to appear on the sets of the reality show, in which she is a participant.

"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," the New York Post quoted a family friend as telling the Hollywood gossip website.

"This is her time to shine and she doesn't want him trying to steal her spotlight," added the Palin family insider.

An ABC executive also confirmed that security is very tight at 'Dancing With the Stars' and if someone is not wanted in the ballroom, it is assured that the person will not be entertained.

Palin is currently living in Los Angeles with her 21-month-old son Tripp preparing for her dancing stint. (ANI)
