Kelly Preston has more than lost the weight she gained while pregnant with her son Benjamin and credits her friend Kirstie Alley for the transformation.

"When I got pregnant at 48, I didn't know if my body would bounce back," Preston told People magazine. "I lost 39 lbs., have more energy than I had 20 years ago and I feel amazing. I'm going to be turning 50 next year... Hey, 50 is the new 30."

Preston credited tennis and Alley's Organic Liaison weight loss program for her slim-down.

"I was so excited when my best friend created Rescue Me," Preston said of the system's organic supplement system that is said to target cravings and boost energy. "It's pretty much the most genius thing ever."

Preston recently signed on as Organic Liaison's spokesperson. In March, Preston told OnTheRedCarpet.com that she had "more than a pound or two" of baby weight to lose and planned to use Alley's products.

"I've seen it, I've tasted it, it tastes great," Preston told OnTheRedCarpet.com at the opening of Alley's "Organic Liaison" health food store in Los Angeles on Wednesday, March 9. "It really is something that is good for you, too. Really good for you."

Preston, 48, welcomed her son, Benjamin, with actor-husband John Travolta in November 2010. They also have a daughter, Ella, who is 10. Their son Jett died at age 16 in 2009.

Alley, a 60-year-old actress and former Jenny Craig diet spokesperson, has struggled with her weight for years and poked fun about the issue on her own television shows. She said that she has lost more than 100 pounds.

Alley's "Organic Liaison" program features organic food and drink products and a "Body Game Manual."
