Jessica Simpson Pumps Iron With Yummy Buns Out

Scroll for the photo. Jessica, a mom of three, whittled herself down 100 pounds after welcoming third baby Birdie Mae in 2019, with the "Dukes of Hazzard" star today proving she's kept the weight off.

The photo, offering a glimpse of how Jessica stays in such sensational shape, showed the blonde shot from behind as she showcased her peachy rear while holding dumbbells and in teeny-tiny black shorts. Jessica also sported a backless black top and T-shape sports bra, with a ponytail keeping things simple.

The snap wasn't all about Jessica, though, with "All about that bundle baby!" encouraging fans to shop a collection of fitness equipment including a jump rope and slimming belt. Jessica Simpson Style has massively branched out, with 2020 seeing the label drop its "Fiend" fragrance, plus Jessica's own 8-year-old daughter Maxwell designing bed linens for the brand.

Jessica will likely shift a lot of her merch with snap. Nothing new for the star who recently slurped spaghetti while in high heels in a promo.

Jessica, who made headlines ahead of the holidays for inking a massive multimedia deal with Amazon, has seen her weight-loss diet publicized, with trainer Harley Pasternak last year revealing:

“She would eat one whole egg and three egg whites for breakfast, scrambled with a bowl of blackberries. For lunch she would have a salad with grilled chicken and grilled fish with salad and vegetables for dinner. As for snacks, she would have almonds and sometimes green beans with Parmesan cheese on top."

Jessica doesn't just let her trainer do the talking. In the summer of last year, the star opened up on her weight loss, revealing that she only eats eggs in cakes after consuming so many of them during her weight-loss journey. Jessica also treats herself to mac and cheese.

"I mean, listen, I have kids, so if I want, I eat like a kid. I like corn dogs and mac and cheese – you don’t limit yourself," she told Hollywood Life.
