Jessica Simpson is one hot mama!
Barely four months after giving birth to her second child, son Ace Knute Johnson, the fashion mogul showed off her incredible post-baby slim down in a new photo for her Weight Watchers' campaign.
Simpson has been vocal about her curvy physique, in response to the backlash about her pregnancy weight gain.
In the snapshot Simpson, 33, rocks a pair of skinny jeans and a white shirt to accentuate her curves, while beaming for the camera.
The fresh-faced "Fashion Star" judge has gushed about her new life as a mother. She's also mom to daughter Maxell Drew, 17 months, with fiancé Eric Johnson.
"With two kids, we have our hands full, but every day is a new adventure," Simpson previously told Us Weekly.
The onetime singer faced some criticism during her first pregnancy — in which gained 70 pounds — but she took it in stride and has since become a mouthpiece for moms with curves, and for her success with Weight Watchers.
"I will never understand why people give pregnant women such a hard time," Simpson said. "We are creating a human life: I think we get every excuse in the world to eat a doughnut!"
"It's okay to gain weight, and it will always come off."
