Baby Bear meltdown as BRISTOL PALIN nosedives on DWTS!

Mark Ballas got a glacial heap o’ drah-ma from Bristol Palin on Dancing with the Stars: All Stars after which the couple hit the floor and danced a paso doble – netting them the eve’s lowest score.

During a practice session, the Palin spawn, 21, bitched to Ballas she felt he was "bummed to have [her] as a partner,” and no doubt would rather have been paired off with a dance partner like Shawn Johnson or Sabrina Bryan, reported.

“I feel like you want to go home," she told Mark, who rhetorically asked, “What am I supposed to f***do?"

Following their paso doble, judge Len Goodman called the routine "easily [Bristol's] best dance," while Carrie Ann Inaba told Palin she's providing herself a worthy competitor.

Despite the lip service, the 22-point total score the couple received — all three judges gave her 7.5 — marked the night's lowest in the ramped-up comp.
