Bristol Palin is giving Dancing with the Stars everything she's got, and as you can see from these photos obtained by RadarOnline.com, her work-outs leave even this hardy Alaskan girl worn-out.
Bristol has been paired with two-time winner Mark Ballas for the ABC dancing competition, and she's moved to Los Angeles, with her son Tripp, for the duration of the season. We caught up with her as she was leaving her rehearsal studio on Saturday.
On Friday's Tonight Show, Bristol told Jay Leno she "tried to make it work" with her ex-Levi Johnston, who is now also said to be pursuing a reality TV career. But, said Sarah Palin's daughter, "he's changed."
