Jessica Simpson can lay claim to many accomplishments in her young life:
She's been a pop star, an actress, a handbag designer, a business mogul, and of course, a mom:
Some folks in Jessica's situation might be inclined to rest on their laurels and become complacent in their achievements.
But not, Mrs. Simpson-Johnson.
No, the mother of three is still dropping jaws on Instagram, and not only because she still knows her way around a bikini selfie.
This week, Jess is making waves thanks to the pic below -- and the stunning revelation that came along with it.
"6 months. 100 pounds down (Yes, I tipped the scales at 240)," she wrote on Instagram.
"My first trip away from #BIRDIEMAE and emotional for many reasons, but so proud to feel like myself again," she added.
"Even when it felt impossible, I chose to work harder."
Yes, Jessica welcomed a baby girl back in March -- and in the months since she's lost an astonishing 100 pounds.
Celebrity trainer Harley Pasternak also shared a pic (above) of Jess, and he sang the 39-year-old's praises in a heartfelt caption:
"Beyond proud of this incredible woman. Been working together for over 12 years and she's always the most warm, sweet, polite, and respectful person in the world," Harley shared on Instagram.
"And on top of it all, after being nonstop pregnant for as long as I can remember, she's down 100 pounds and looks younger today than she was when we met.
"Shout out to the awesome @sydneyliebes #fitclients #jessicasimpson."
Jess has yet to go into detail about exactly how she lost all that weight, but you can bet details are forthcoming.
After all, Simpson is nothing if not candid with her fans.
Jessica flaunted her massive baby bump in an unforgettable Instagram pic while she was carrying baby Birdie, and throughout her latest pregnancy, she opened up about her various difficulties in refreshingly frank social media posts.
Jess is no doubt a talented singer and actress.
But it's that candor and self-deprecating sense of humor that fans have really responded to over the course of her career.
Oh, and as a bonus, she might now be able to tell us all how to drop 100 pounds in six months!
