Did Kylie Jenner get a boob job?

That's what fans are speculating after the 19-year-old posted a series of photos on her Instagram page where her curves are noticeably curvier. In the racy pic, Kylie's boobs appear out of control in a ultra-fitted red leopard print bodysuit.

Kylie is no stranger to defending herself from plastic surgery rumors. After months of speculation — and a plumper pout! — the makeup mogul finally admitted that she’s experimented with lip injections, and she even revealed that she once took it a step too far and made her lips a little too big.

"I definitely made my lips a little too big at one point," she told Allure magazine over the summer. "I got excited and felt like I needed to do a lot. And then you guys were like, 'Kylie, you need to chill.' And then I had to go back and have it fixed, and it was a crazy process. Thank God I didn't end up on ‘Botched.'"

Kylie previously had fans questioning her new curves when she shared yet another series of photos showing off her ample cleavage earlier this year. But she took to social media to shut down the allegations by blaming her increased bust line on her menstrual cycle.

"TMI but it's that time of the month lol," she responded to a fan's question about her newly enhanced cleavage on Twitter.

Just like her older sisters Kim Kardashian and Khloe Kardashian, Kylie is not shy about showing off her dangerous curves with sexy photoshoots. She even made a curious choice earlier this week when she decided to break her social media silence after her brother Rob Kardashian’s explosive break up with his girlfriend Blac Chyna —who is the ex-fiancé of Kylie’s current boyfriend Tyga — with a butt photo.
