Jessica Simpson exuded class at the White House Correspondents’ Dinner in Washington, D.C. on Saturday, and she added some sizzle to that class with her newly define waistline and stunning figure. She and fiance Eric Johnson attended the gala together, but all eyes were on Jess and her strapless floor-length Carolina Herrera flowered gown. She accessorized her look with a bracelet and earrings designed by Neil Lane.

A spokesperson for Weight Watchers, Simpson looks fabulous after having two children in the past few years.

“I love this body and what it’s capable of—no matter what size,” Simpson says in a Weight Watchers commercial. “But this version, feels really good. My body, like my life, is a work in progress, but I’m getting there, with Weight Watchers.”

This isn’t Jessica’s first reveal, however, since her weight loss. She and Johnson were spotted at a Mexican restaurant called Sagebrush Cantina in Calabasas just a few days ago. She wore snug jeans and a sexy black top that revealed her black bra underneath.

Even though she has kept up her Weight Watchers eating plan, Jessica Simpson has lost a good portion of her weight chasing her two small children around. She also loves taking walks–with or without the kids–and sometimes works up a sweat gardening her her own back yard, too.

During an interview with Good Morning America, Simpson said she wants to set a good example for others–especially for her children.

“I really do feel this need to be the best role model for my children,” she said. “I want [Maxwell] to look up to me and want to be like me…I don’t want to give her any false perception of what is real and what’s important.”

Jessica Simpson has certainly met her post-pregnancy weight loss goals and showed it off in style at the White House Correspondents’ Dinner this weekend. Her family activities alone will no doubt help her keep the weight off.
