Kellie Pickler has always had a hot body, but after claiming the mirrorball trophy on this season's Dancing With the Stars, the country cutie flaunted a seriously flawless figure thanks to hours of grueling rehearsals and intense on-air dance-offs.
And she's certainly not the only one!
The competition show has transformed the bodies of tons of celebs, proving that cardio dance and mega-pressure to win can burn some serious calories.
Plus, celebrity moms like Bristol Palin, Jennie Garth and Tia Carrere dropped the baby weight by breaking a sweat in the studio, and even a few of our favorite funny girls like Kirstie Alley and Margaret Cho slimmed down considerably from the intense choreography learned on and off-camera.
We have to say, we're totally impressed!
No matter how each star placed in the actual competition, it's pretty clear that they're all winners at weight loss.
Who do you think has had the most impressive Dancing with the Stars body transformation?
