Jessica Simpson is celebrating a major milestone.
The mother of three, 39, took to Instagram Tuesday to reflect on her weight loss journey since giving birth to daughter Birdie Mae Johnson in March.
"6 months. 100 pounds down (Yes, I tipped the scales at 240)," she captioned a picture of her svelte postpartum figure in a head-to-toe black outfit, including stunner shades.
In another picture, Simpson embraces her "little labor of love," whom she shares with husband Eric Johnson. The couple also have daughter Maxwell, 7, and son Ace, 6.
"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."
Simpsons' famous friends applauded her effort.
"YAS KAWEEEEN you have and always will be my inspiration," said "Jersey Shore" star Nicole "Snooki" Polizzi, while actress January Jones wrote, "Wowza lady, you look (bomb)."
Katie Couric added, "You look amazing!"
Baby Birdie was born March 19 weighing 10 pounds, 13 ounces, Simpson's rep, Lauren Auslander, confirmed to USA TODAY.
And Simpson said time is flying by. "6 months already?!?" she captioned a black-and-white picture of her smiling baby girl.
No matter how fast Birdie grows up, the actress and singer said she's enjoying every moment with her newest addition. "While the other 2 kiddos are off at school, this little lady and I snuggle a lot," she wrote alongside a picture of her and Birdie cuddling.
