Bristol Palin Hasn't Lost Weight On 'Dancing With The Stars'

The grueling rehearsals of 'Dancing With the Stars' have caused many contestants to slim down, but not Bristol Palin.

"I haven't really noticed a change in [my body]," she told Access Hollywood. "I think most people lose weight [on the show] because they're too stressed out to eat. I haven't had that problem!"

People reports that Bristol's legs have toned up and she will be showing more skin next week:

The Alaska native, who says she doesn't weigh herself and doesn't notice any changes in her body except for toned legs since joining DWTS, will sacrifice any physical insecurities for the sake of staying on the show.

"We're doing the sexy dance next week, and I have to get into character," she says. "Dressing sexy will help me get into character more. Next week, I'll be dressing sexy. This is it."

Meanwhile costar Audrina Patridge is fitter than ever.

"I would say I'm in the best shape of my life," she told Us Weekly. "Dancing is so different than going to the gym. I'm going to be so sad when it's over!"

Kelly Osbourne famously lost a lot of weight during her stint on 'Dancing' and has since managed to keep it off. Erin Andrews said that her ten-pound 'Dancing' weight loss made her "too thin."
