Since Bristol Palin last appeared on Dancing With the Stars two years ago, she claims to have grown up a lot. And while her maturity levels and confidence may have changed, her physical appearance has transformed too.

The young mom, who first danced with Mark Ballas on Season 11, is showing off a much slimmer figure now (right), than she did her first time on the show (left). After all, Bristol told People that her goal this season is to not gain weight on the show — with the 24/7 rehearsals, that sounds like a reasonable goal to us!

What's more, the young dancer seems more stylish and put-together now that she's been in, out, and back into the limelight. It looks like we're in for a whole new Bristol when the show starts in a few days!

Dancing With the Stars Season 15: All-Stars will premiere on Monday, September 24 at 8 p.m. ET/PT on ABC. Check out the full All-Stars cast list here.
