Simpson, 34, wed her longtime partner, Eric Johnson, 35, on July 5. Their two children, Maxwell, 2, and Ace, 1, were on-hand for their parents' nuptials.

"I feel sexier as a wife and a mom," Simpson said. "[Marriage] actually has changed my style. I'm very into like, slip dresses and everything a little bit sexier."

Now that she's changed up her wardrobe, Simpson is ready to put away her maternity clothes for good. Two children, she said, were enough for her.

"[But] what if there is another one that's supposed to happen? I don't know!" she said. "I can't say never but I would think, sitting here in front of you, I would probably say never again."
