(CNN) - This time four years ago, Bristol Palin was promenading across the country as she campaigned for her mom's Republican vice presidential bid.
Now she's taking part in a different whirl–as a returning guest on ABC's "Dancing with the Stars."

With mom cheering alongside, Bristol took the stage Monday night with the show's "all-star" cast of former contestants. Bristol placed third when she competed on the series in the fall of 2010, another prime election season.
Sarah Palin, former Alaska governor and Sen. John McCain's 2008 running mate, sat in the front row to watch her daughter perform. The conservative firebrand also posted a photo of Bristol and Bristol's three-year-old son, Tripp, on Facebook Monday night.
"Tripp surprised his mama backstage at DWTS tonight," Sarah Palin wrote, urging supporters to call in and vote for her daughter.
While she hasn't been on the show for two years, Bristol has kept a high profile on other reality programs, including the TLC's "Sarah Palin's Alaska" and Lifetime's "Life's a Tripp."
In her first routine Monday, Bristol did the Cha Cha Cha with her same partner from 2010, Mark Ballas. The three judges praised the reality star for appearing more confident than her first season.
Other celebrities coming back to the show include actress Kirstie Alley, actress Pamela Anderson, singer Joey Fatone, Olympian Shawn Johnson, and former NFL star Emmitt Smith.
The stars return to the airwaves Tuesday night for part two of the season's premiere.
