Actress Kelly Preston was spotted at the 9th Annual TV Land Awards in a slinky gold dress looking skinnier than ever. Her secret? Kirstie Alley!

Preston credits her BFF and fellow Scientologist's organic weight loss supplement system with helping her lose 39 pounds of baby weight she gained while pregnant with Benjamin.

"When I got pregnant at 48, I didn't know if my body would bounce back," she said. "I lost 39 pounds, have more energy than I had 20 years ago — and I feel amazing. I'm going to be turning 50 next year — holy (expletive)! Hey, 50 is the new 30."

"I was so excited when my best friend created Rescue Me," Preston gushed over the Rescue Me kit that's part of the weight loss system. "It's pretty much the most genius thing ever."

Did we mention that Preston also just signed on as the spokesperson for Organic Liaison?

Alley's weight loss program consists of supplements and a diet plan. "Organic Liaison is a weight loss and diet plan that offers organic weight loss products, natural dietary supplements, and access to online diet and exercise tools to help you lose weight safely and effectively, all while having fun!" the website says.

Besides her new body and gig, Preston has another milestone to celebrate. "We just celebrated Ben's first birthday," she says of her son with John Travolta. "I can't believe it's already been a year."
