Earlier this month, Kelly Preston announced that she had lost nearly 40 pounds thanks to an intense fitness regimen and Kirstie Alley’s Organic Liason diet program. The actress, who called the program “the most genius thing ever,” was afraid she would have trouble at age 48 dropping the baby weight gained after her third pregnancy.

"I lost 39 pounds, have more energy than I had 20 years ago — and I feel amazing," she says. "I'm going to be turning 50 next year — holy s---! Hey, 50 is the new 30."
