Get it, mama! Kylie Jenner gave birth to her daughter Stormi Webster less than two months ago, but she's already back to flaunting her flat, post-baby tummy. Kylie's snapback game was definitely strong and her waist is as tiny as it was pre-pregnancy. Watch the video above to see Kylie's post-baby weight loss.

Of course, fans are dying to know her secret about how she got her waist snatched so quickly after giving birth, and earlier this week Kylie took to Instagram to reveal what she used to help her get her body back. "My girl @premadonna87 hooked me up with the @waistgangsociety snap back package," she wrote in the caption of a photo of her wearing a waist trainer. "Waistgang has the BEST quality snapback products."

But she got a ton of backlash from fans online for promoting waist trainers because many deem it as an unhealthy way to lose weight. "My god is Kylie still advertising waist trainers (NOW POST GIVING BIRTH) to teenage girls," one fan wrote. "How can u be so filthy rich and still sell out for something that is so dumb and could potentially perpetuate negative body image in young girls."

Insiders revealed that Kylie gained about 50 pounds during her pregnancy and at her heaviest, she weighed 180 pounds. The 20-year-old enjoyed herself while she was "eating for two" and she often indulged in her pregnancy cravings — which included lots of In-N-Out. But in just one month after giving birth to her daughter, Kylie lost an impressive 35 pounds but it seemed like she put a lot of pressure on herself to do so in such a short amount of time.

"She called herself 'fat,' 'gross,' and 'disgusting' all the time," an insider told Life & Style exclusively. "There was no way Kylie wanted to be seen in public. Now she feels like she’s got a lot to prove."
