Bristol Palin is back in the 'Dancing with the Stars' ballroom

How do you follow Gilles Marini’s sizzling turn on the dance floor?

If you’re Bristol Palin, you have to be asking yourself that very question.

Of course, with encouraging words such as “Shake that a–“) from her partner Mark Ballas (during their rehearsal video footage)…. how could she NOT be ready for her big return to the ballroom (as proud mama Sarah Palin looked on from the sidelines) with the ever booty-shaking cha-cha -cha.

Carrie Ann called her “most improved,” while Bruno called her “refrehsed, revived and refurbished” … Len liked her legs, not her arms.

Her score: 19.5 out of 30.

But as Mark pointed out about his partner: “She’s beautiful and having a good time.”
