Jessica Simpson Drops 100 Lbs. — See Her Post-Baby Body!

On Tuesday, Simpson posted pics of her post-baby body in a form-fitting black dress. She wrote on Instagram, “6 months. 100 pounds down (Yes, I tipped the scales at 240 😜).”

Referencing her baby girl, she added, “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.💚.”

In response to the photo, actress January Jones said, “Wowza lady, you look [strong].” Katie Couric added, “You look amazing.”

Jessica enlisted the help of celebrity trainer Harley Pasternak to help her lose the baby weight. Harley reposted Jessica's photo, adding, “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. 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."

Earlier this month, Simpson posted a full-length pic of her post-baby body at husband Eric Johnson's birthday celebration. She shared, “Happy 40th Birthday to the man of my dreams. I pray in every lifetime I find you and we re-create the beauty of what we have again and again. My hero, champion, best friend, lover, and daddy to our babies...I could never have hoped for more. I love you. Let's celebrate.”

In May, two months after giving birth to Birdie, Jessica was already hard at work to shed the weight. Along with a pic of herself in athletic gear, she joked, “Just stretching it out in my rubber corset. The joy of postpartum.”

Simpson was likely referring to a postpartum belly support wrap underneath her athletic gear.

Leading up to Birdie's birth, Simpson was open about her pregnancy struggles on Instagram, sharing photos of her swollen ankles, a broken toilet seat, and her bare belly in a bikini!
