Jennie Garth, 40, has a new body … and a new attitude. After her split from hubby of 11 years, Twilight's Peter Facinelli, 38, Garth turned over a new leaf and dropped 30 lbs. in just a few months.

"Forty is like the new little black dress," she told People. "I really feel like that part of me was dead and I need to shed it off," Garth, who has three children, says about her lost weight. "I got rid of the old and in with the new. A lot of exercising and a lot less eating … I decided to start taking better care of myself."

And to end on a high note, Garth emphasized what many have suspected for years. "Forty is the new 30," she said.
