Kylie Jenner on Plastic Surgery Allegations: 'I've Never Been Under The Knife'

Plus, which sister is more like a mom to her than her own mom?

Kylie Jenner is so over people talking about her lips.

The 17-year-old sets the record straight about rumors she’s had plastic surgery to enhance her pout in the new issue of Grazia magazine.

“I'm like, ‘Stop talking about my lips,' she says, before declaring, "I haven't had plastic surgery. I've never been under the knife.”

Kylie’s changing looks causes a lot of chatter –but she insists it’s just because she’s growing up.

“People flashback to pictures of me when I was 12 and say, 'Kylie's so different' but how can I look the same from 12 -18?" she asks.

The Keeping Up with the Kardashians star also admits she’s closest with her big sister Kendall but notes Khloe is a close second.

“I'm closest to Kendall, I spent every second with her growing up,” Kylie says . “After that, it's probably Khloe.”

“Khloe is more of a mom to me than my mom is sometimes. My mom is all about being best friends.”

In the new season of Keeping Up With the Kardashians, Kylie even tells dad Bruce that she hasn't spoken to her mom in two weeks. Weird? You can see the clip by checking out the video above.

Of course, this isn't the first time she’s addressed all the speculation around her lips. Earlier this year, she told Cosmo, "You guys have watched me grow up since I was 9. My face is going to get different. Now, I know how to do my makeup, contour and everything. I'm not against surgery. I'd never say no, but I don't desire it right now.”

And Scott Disick can even confirm it takes her over 40 minutes to get her pout ready. "Have you seen her do her lipstick? It takes like 40 minutes, and then she, like, pulls one lip, pushes one out," he revealed on a recent Keeping Up With the Kardashians episode. 

What do you think? Is Kylie being honest? Or, are you still wondering if she’s had any sort of lip injections? Let @Katie_Krause know on Twitter!
