Jessica Simpson is living proof that Weight Watchers works!

The 33-year-old mom of two dropped by Good Morning America Tuesday, Jan. 7, to show off her amazing, svelte post-baby body and talk about how the weight loss program helped her to shed those pregnancy pounds--twice!

"I believe in it with all of my heart," she told GMA lifestyle anchor Lara Spencer. "It's a lifestyle. I've tried so many different diets, and you can only stick to something for so long. I feel like with Weight Watchers, it just becomes a part of who you are."

Jess admitted during her first pregnancy with daughter Maxwell (now 20 months old), she "didn't care" about weight gain, saying, "I just let myself have whatever I wanted!"

But when she was pregnant with her second child Ace (now 6 months old), she wasn't "as relaxed in my eating and everything [the way] I was with Maxwell."

"I had already been on Weight Watchers, and I had already lost over 50 pounds," she said. "I was just already in a healthier regimen, so I kept walking and staying active—and Maxwell started walking!"

Maxwell and Ace are a huge part of why Jessica is committed to maintaining a healthy lifestyle. "I really do feel this need to be the best role model for my children. I want [Maxwell] to look up to me and want to be like me," she said. "I don't want to give her any false perception of what is real and what's important."

One thing that is most definitely real and important is Jessica's relationship with fiancé Eric Johnson, whom she hopes to marry sometime in 2014. "We don't have an actual [wedding] date, but we do know that we want it to be this year. We need to get married!"

"I already feel like we're an old married couple already," she quipped. "Like, if he wanted to run, he could've run when I was hormonal and pregnant."
