Kelly Preston Weight Loss: How She Dropped 39 Pounds

In Hollywood, the spotlight shines bright on pregnant celebs long after the doctor says "It's a boy" -- the pressure to reveal a "Wow"-inducing post-baby body is more than tough. After Kelly Preston gave birth to son Benjamin just over a year ago, she wasn't sure she'd ever get her body back.

"When I got pregnant at 48, I didn't know if my body would bounce back," she told People.

But keeping in true Hollywood fashion, Preston went above and beyond losing a little baby weight. The actress has lost almost 40 pounds and is feeling better than ever: "I'm going to be turning 50 next year -- holy s---! Hey, 50 is the new 30."

So how did she do it? Preston credits Kirstie Alley -- who's also been looking good lately -- for her transformation. Preston stuck to Alley's Organic Liaison weight-loss regime that relies on organic supplements.

Organic never looked so good!
