It looks like Jessica Simpson’s hard work has really paid off!

Weight Watchers, a healthy eating weight loss company, just released it’s new commercial featuring spokeswoman Simpson, and the fashion designer shows off her incredible slimmed-down curves only eight months after giving birth to her second child!

The mom sports a stunning skintight white dress in the ad and gushes that the program has led her to “a newfound determination that I’m really proud of.”

The recording artist also adds, “I can honestly say that I’ve never been happier.”

Simpson has been a spokeswoman for the brand since she gave birth to daughter Maxwell in May of 2012. She was well on her way to losing the 70 lbs. she gained during her pregnancy until she became pregnant again six months later.

Simpson in January of last year

This time around, the 33-year-old didn’t have quite as much to lose and shared in one of her commercials that her upcoming wedding to fiancé Eric Johnson was one of her biggest motivators.

“The new year will definitely bring on the wedding bells which is exciting…I think it’s about time,” the blonde beauty shared.

“Knowing that I have the wedding coming up is an incentive to stay on Weight Watchers, count my points and stay in the gym. I mean, when you see my dress, you’ll know.”

But Simpson’s desire to lose weight with the company for a second time wasn’t just about looking her best in a bridal gown. “I’m just trying to feel good in a pair of jeans and a T-shirt,” the reality star said.

“I can’t wait to be able to feel just comfortable in my skin and know that I’m back to the person I’ve been before.”
