Kylie Jenner's lips have been a hot topic for quite some time now. We're just fascinated by how someone can change their appearance so drastically without the help of a plastic surgeon.

If you've been keeping up with Kylie's Instagram, you've seen the shocking transformation over the past year. Her lips have practically doubled in size! But still, the reality star denies getting lip injections and seems to get frustrated when she's questioned.

"I feel like everyone has been talking about it for months, so I'm kind of sick of it," she told E! News. "In pictures, I pout them out a lot."

No, Kylie. One does not simply pout their lips and make them magically increase in size. Other excuses she's made for her change in appearance are puberty, lip liner, and good lighting ... but it just doesn't add up. Take a look at the before and after comparison:

"These plastic surgery rumors hurt my feelings to be honest are are kinda insulting," she tweeted earlier this year.

It goes without saying that the reality star still looks gorgeous, but it seems like this mystery is never going to be solved.

"I don't even care anymore. I'm like whatever, just say whatever you want," she said.
