Jessica Simpson Flaunts Body In Busty Dress After Losing 100 Pounds!

Jessica Simpson can't stop celebrating her incredible weight loss!

The star, 39, who gave birth to her third child just six months ago, revealed on Tuesday that she's lost the baby weight—a whopping 100 pounds.

And on Wednesday, September 25, she was spotted outside The Bowery Hotel in New York City in a form-fitting little black dress that showed off her bust, tummy, and legs!

Simpson wore black high heels and her blonde hair down.

She welcomed Birdie Mae Johnson, her third kid with husband Eric Johnson, on March 19. Birdie was a massive baby, as she weighed in at a whopping 10 pounds, 13 ounces at birth.

As RadarOnline.com readers know, Simpson was believed to have gained 100 pounds during her pregnancy and she confirmed that in her recent post.

Simpson told fans on social media this week that she had quite a weight loss journey: “6 months. 100 pounds down (Yes, I tipped the scales at 240),” she wrote. “My first trip away from #BIRDIEMAE and emotional for many reasons, but so proud to feel like myself again. Even when it felt impossible, I chose to work harder.”

The star shared two photos of herself looking chic in a black dress, heels, and matching sunglasses. In one photo, she is seen smiling while carrying her baby girl.

The former Newlyweds star and ex-football player Johnson welcomed their third child in Los Angeles.

The pregnancy was hard for Simpson and the "Irresistible" singer shocked fans by sharing a photo of her badly swollen pre-birth feet on Instagram.

Before the birth, Simpson also shared a shocking photo of her massive baby bump.

Birdie finally joined Simpson and Johnson's two other children, daughter Maxwell Drew Johnson, 7, and son Ace Knute Johnson, 6.

“Jessica is extremely sensitive about the way she looks, and yet she refuses to fight her cravings,” a source said during Simpson’s pregnancy.

An insider told RadarOnline.com earlier this year that after their third child's arrival, Simpson wanted her husband, 40, to go on a diet with her.

“Eric eats like a circus animal and while he’s in charge of the grocery shopping and a lot of the cooking in the house, he’s anything but health conscious,” the insider said about his eating habits. He “would keep indulging in junk food but Jessica is determined that they’ll both get into tip-top shape again.”

This summer, a source told RadarOnline.com that she was determined to drop her baby weight as quickly as possible.

Now it looks as though the star has achieved her goal!
