Kylie Jenner just wants the plastic surgery rumors to stop.

The 18-year-old decided to come clean on her new website and app, and revealed that she hasn't gone under the knife at all (she swears!) – and that anesthesia has a horrible effect on her.

"I've only been under [anesthesia] once before, when I went to the dentist and I didn't react well; it really scared me," she wrote. "I threw up and I was SO nauseous the next day. But as of now, I only have lip fillers."

As for her boobs? Well, in addition to her Victoria's Secret bra that she swears by, she also attributes weight gain to her bigger cup size. And that nose job she's rumored to have gotten? It's called contouring!

"No, people—I haven't gotten breast implants! Everyone is obsessed with that. Truth is, as I've gotten older, I've gained 15 pounds and my body has changed; I've definitely filled out. Working with some of the best makeup artists has taught me a lot of amazing tricks to making me feel more confident and I can't wait to share them with you guys," she wrote. "I swear there are things you can do to work on problem areas without having to think about plastic surgery. (Contouring has changed my life!)"

Of course, makeup can only do so much, and Kylie admits that plastic surgery may be in her future.

"I'm also someone who says 'never say never.' If, down the line, I get to a point where I'm really uncomfortable with something on my body, I'm not against changing it," she said.
