How did she do it?

"When you get sad, you either overeat or you become really healthy," a Garth pal explained. "Jennie's taking care of herself — she's taken control of her situation."

And the newly single mother of daughters Luca, 15, Lola, 9, and Fiona, 5, is now feeling confident. "Before, she used to be like, 'OK, let's cover me up,' " the Garth pal said. "And now she's more open-minded about having fun with her clothes. She's feeling good in her skin."
