Well, Bristol proved worthy when she danced the cha cha to Three Dog Night’s “Mama Told Me Not To Come,” complete with a dramatic costume change. She began buttoned-up in a gray suit – reminiscent of something her mother might wear, Ballas said – before ripping it away to reveal a skimpy red, fringe dress. PHOTO: Bristol Is Miss Modest in Her Dancing Costume Though many thought her mother, former Alaska Governor Sarah Palin, would be in the audience, she was not in the ballroom but did Tweet a photo of the viewing party taking place in her living room. “Over-the-moon excited and happy for Bristol!” she posted. “Cheering her on @ DWTS party in the Palin living room.”
