It didn't take long post-giving-birth for Kylie Jenner to get back to doing what she does best: posting sexy selfies on Instagram. While we're literally amazed by how quickly Kylie got her old body back, fans think they've spotted one big difference. They believe her booty is bigger than ever, and (to no one's surprise) they're calling butt implants.

One photo in particular from Kylie's recent trip to Turks and Caicos for Travis Scott's birthday has fans thinking Kylie got some work done while she was flying under the radar over the past year. The pic is just the silhouette of Kylie on a paddleboard, and her booty definitely stands out. "Butt's way too big for your body, easy on the injections mama :)," wrote one fan. "Did Kylie get her butt done again along with that tummy tuck?" questioned another. Some savage supporters even compared her body to "an ant," "a seahorse," and "a dirty diaper." So mean!

Luckily, Kylizzle also had some fans that jumped to her defense. "Guys, when you are pregnant with a baby girl, you gain weight around the thighs and butt. So after giving birth to Stormi, she just became extra thicc around there," wrote one. And they're right. It's normal, and totally healthy, for a woman to store fat in her booty after pregnancy, which will benefit her baby later. "The rear end is exactly where we want a woman to put on weight," Kathleen M. Rasmussen, Sc.D., R.D. told Parents. "Fat stored there is not visceral, it doesn't end up in hard-to-break-down adipose tissue the way it would in her abdomen, making it much easier to lose after pregnancy."

Luckily, Travis is crazy about her new look. "Travis loves her curves and post baby thickness. He compliments her and kisses her all over her body," a source told In Touch exclusively. They’re just young and in love."

Kylie has recently spoken out about her future plastic surgery plans, saying, "I feel like if it makes you feel better, and if that’s what you want to do, I’m not against it. Right now I probably wouldn’t do anything, actually." In the past she admitted to getting lip injections, but fans have long speculated that she also got her booty and breasts done. Looks like that's only going to get worse!
