You've probably seen Jessica Simpson frolick around with a dog on a lawn in the Weight Watchers commercials, but now, the singer is taking her weight loss transformation to the morning shows.

Jessica stepped out for Good Morning America on January 7, showing off her slim figure in a black and nude dress paired with beige pumps.

"Good Morning, America! Going live soon! #weightwatchers," she wrote, along with a photo of herself looking super fit before the show.

Jessica and her fiancé Eric Johnson have two children, a 6-month-old son named Ace, and a 20-month-old daughter named Maxwell. Since having her second child just 14 months after her first, Jessica has been working with Weight Watchers to shed the baby weight.

"It's a lifestyle, I have tried so many diets and I feel like with Weight Watchers it just becomes a part of who you are," she said. "As a mom, I just have this confidence: I just feel so proud of what I've done and what I've accomplished — and I just do feel this need to be the best role model for my children."

Doesn't Jessica look amazing? What a hot mama!
