Jessica Simpson
is showing off her sexy side!

The blonde bombshell flaunted her slimmed-down figure in a tight, all-black ensemble during a family dinner in Calabasas, Calif. on Saturday.

The mother-of-two looked chic and sophisticated in a sheer black top, black skinnies and embellished sandals. She left her signature long locks down in a sleek and straight style, opting for a more natural look with simple eye makeup and a red lip.

With two kids, a successful fashion line, and an upcoming wedding to plan with fiance Eric Johnson, she definitely has her hands full. But, she's clearly been working hard on her post-baby body!

In a recent interview on "Good Morning America," Simpson admitted she was "so insecure" about her body after giving birth to daughter Maxwell in 2012. "I couldn't even believe what I weighed," she said. "I don't think that I ever expected myself to see the numbers that I have seen on the scale."

That said, she doesn't think any woman should be ashamed of pregnancy weight gain.

"You are creating a life, and honestly it's not easy," she explained. "It is a really hard thing to go through. And you deserve to eat your ice cream, you deserve to have your pancakes. Do whatever you want to do and then afterwards just know that you have to work really hard."

She doesn't look like she's eating too much ice cream these days!
