The HLN host talked to Anderson Cooper about finally losing the weight she gained when she was pregnant with her twins -- now four.

"I never really cared about it or bothered to lose it," she says. "I lost it like this, so I'm happy about it."

Nancy's weight loss is reminiscent of another "Dancing" alums body transformation -- Kirstie Alley famously lost 30 pounds during last season's competition.

In addition to Nancy and Kirstie -- current competitor Ricki Lake is also slimming down on the show -- she's reportedly lost more than 20 pounds and admitted she was inspired by Alley's transformation.
