Wynonna Follows Her Heart for 'DWTS'

"I'm trying to get back to my original weight of 8 pounds 15 ounces," Wynonna likes to joke. "I've been asked so many times that it's become a knee-jerk reaction. I go there because I cannot be defined. I am more than a number on a scale or a chart."

ET was invited to Wynonna's Tennessee home to watch her practice the Cha-Cha with Tony, and she says that all the dancing has already started to help change her eating and exercising lifestyle.

"Honestly, the more you dance the more you drink water and take care of myself," she says. "Do the action and the heart will follow."
