Sarah Stage is bringing a whole new meaning to the phrase "post-baby body".
The fit model first made headlines for having the tiniest baby bump ever (left) and now she's creating more buzz for her incredible physique after giving birth.
The social media star welcomed her son James Hunter less then a week ago and took to Instagram to show off her unreal body (right).
In the snap, the 30-year-old dons a leopard print bra and black underwear as she snaps a selfie ... looking like she wasn't ever pregnant in the first place.
"4 days post baby. Total pregnancy weight gain was 28 pounds. I'm excited to resume my workouts in 5 weeks!! #JamesHunter #HealthyBaby #GrannyPanties," she captioned the photo.
Sarah's well documented pregnancy came under fire by some who thought her "skinny" appearance was harmful to her then unborn baby. The star appeared on "Good Morning America" last month to address the uproar and defend her appearance.
"As long as the baby is healthy I don't think anything else matters," she said at the time. "That should be the most important thing."
The model welcomed her son on April 14th, weighing in at 8.7 pounds and 22 inches long -- and he's adorable!
