"Thanks to Beverly Hills Rejuvenation Center's health and wellness program, I've done some CellSound therapy – which evaporates your visceral fat and tightens your skin up. It's just like a whole new me. And, you know, I bought my first tank top a couple of months ago, and now I have a couple more.

"I feel really comfortable in my own skin, wearing just a tank top or no shirt at all," Gosselin added. "It's kind of weird for me because I've always been very conscientious of my weight and my appearance outside of my house. But I'm excited.

"I'm excited to perform and spend time with my kids, go to the pool and that kind of stuff. And, you know, it's been … it's been a totally different lifestyle change."

"We have to have something that's bio-friendly and organic," Rodriguez said of CellSound. "We get the fat cells to open up, leak out their fatty content, which is fatty acids, and we put a very significant energy demand on the localized area while we're doing that. We actually burn over half of the fatty leakage as fuel. So it's safe." 

"It's just like a whole new me. And, you know, I bought my first tank top a couple of months ago, and now I have a couple more."
