Jessica Simpson couldn't be prouder of herself.
The 39-year-old took to Instagram on Tuesday to share her weight loss journey -- since giving birth to 6-month-old daughter Birdie Mae in May -- with her followers.
"6 months. 100 pounds down (Yes, I tipped the scales at 240 ????)," Simpson wrote alongside a photo of herself rocking a head-to-toe black outfit.
"My first trip away from #BIRDIEMAE and emotional for many reasons, but so proud to feel like myself again," the mom of three continued. "Even when it felt impossible, I chose to work harder. ????"
Many of Simpson's fans praised the business mogul. "You always look so beautiful, but especially today. You are an absolute inspiration to all of us," one commenter wrote.
"I'm crying ????????????????????I love you Jessica! Always beautiful but I'm so proud of you!" commented another person.
"???? Love your honesty," stated one individual. "You're such a positive role model for mamas and women!"
In addition to Birdie Mae, Simpson and her husband, former NFL player Eric Johnson, 40, share two children together: daughter Maxwell, 7 and son Ace, 6.
