Part of "gma's" sexiest star secrets to reveal how they are looking and feeling their best and you certainly do. Good morning to you, jessica. Good morning. Congratulations on the birth of your snuggle bug as you called him. He is my snuggle bug. Little ace. He six months but he's -- he is definitely wearing about ten months clothing. That's a tall guy. Yeah, he's definitely -- both of my kids are really tall which I'm going to just be looking up to my entire family. That's a beautiful thing. Tall and healthy, most important. How is big sister maxwell having to share? She is really good. She's really good at taking care of him and helping me with the bottle and she has her baby dolls now so we have all kinds of cabbage patch kids and baby dolls she changes diapers when i change diapers. She's very helpful actually for only being 20 months. Yeah. They are very close in age. Just over a year. Yes. 14 months. Wow. I know. It's been -- it's been a long 2 1/2 years. A long 2 1/2 years and you've been very vocal about you put on a pretty good amount of weight which by the way you're supposed to when you get pregnant. Yeah. I just let myself have whatever I wanted. I didn't care. It wasn't about weight gain to me. It was really just about -- but you've always maintained a healthy lifestyle. Yeah. And then clearly that has paid off. It has. It has. When I was pregnant with ace, my second, I had already been on weight watchers and I had already lost over 50 pounds so i didn't -- I wasn't as relaxed in my eating and everything that i was with maxwell but I was just already in a healthier, you know, regimen so I just -- i kept walking and staying active and maxwell started walking. You are a paid spokesperson for weight watchers. I know you believe in it wholeheartedly. You said -- it's not a diet it's a lifestyle. It is a lifestyle and I've tried so many different diets and, you know, you can only stick to something for so long and I feel like with weight watchers, like it just becomes a part of who you are, you know, and I -- this time around after having ace I did something called simple start which is what they're promoting now and it jump started everything for me. I lost like almost ten pounds like in just two weeks on this beginning. And you've been honest. Women -- we all talk about it all the time. We're held to very high standards and at times in our lives after giving birth or when they're pregnant it's got to be exhausting to be in the public eye but you seem very in control and we have a picture. You're on the cover of "redbook" in february looking van tass tick. You say you're much more in control of who jessica is. As a mom I have this confidence and I just feel so proud of what I've done and what I've accomplished and I really do also feel this need to just be the best role model for my children and I don't want maxwell to -- you know, I want her to look up to me and want to be like me and I don't want that to be -- I don't want to give her any false perception of what is real. What's important. And what's important and it is important to really know yourself and love yourself and through weight watchers I really did get an opportunity to do that because I was setting small goals for myself and I was achieving them and it wasn't just like one big goal. Like every week I gave myself these small goals and it just kept me going and I was just so impressed with myself. I'm like, objection, my gosh, i can do this. In the meantime, two children looking fantastic and running like an empire. Clothing empire continues. It does. That work has not stopped. But it's -- it's the most gratifying thing in the world now to see maxwell my little daughter -- in your clothing. Her little tush has my insignia on it. She's in 2t, 3t. And we have that in the collection. You're doing babies. I've seen your shoes everywhere. You're in macy's commercials.
