When Kendall Jenner wore a sheer Calvin Klein Collection dress to the Harper’s Bazaar Icons party last Wednesday it appeared as though she had a nipple piercing -- and all hell broke loose. Now that the dust has settled and she's covered up her perky tatas, the supermodel is coming clean on her piercing -- and admitting that she does in fact have metal rods jabbed through her nipples.

When asked about the S&M piercing at an event for Estée Lauder’s new fragrance, the reality star didn't shy away from the direct question. The 19-year-old admitted to Page Six, “It is true. I was going through a period in my life, having a rough time, being a rebel and was like ‘Let’s just do it.’”

It comes as a bit of a shock that the classiest of the Kardashian sisters got such a raunchy piercing, but she wouldn't be the only sister in the fam to have done the deed. Earlier this year, Kylie all but admitted to getting her nips pierced on Snapchat.

Kendall says she almost didn't go through with it. “[I was] so terrified, I’m laying on the bed like ‘Why am I doing this?’ Honestly, it hurt, but wasn’t as bad as everyone made it seem and maybe because everyone hyped it up and I thought it would be really, really bad. Then it wasn’t as bad as I expected," confessed the brunette.

And while Kendall may be all about confessing her body modifications, it seems as though her sister Kylie is still being tight lipped about her looks, flat out denying she's had any plastic surgery. Last week she posted a video on the new site trying to shut down any rumors she'd have a boob job, crediting her fuller bosom to Victoria's Secret Bomb Shell bra for the added curves. Personally we think it's a clever ploy to advertise for the lingerie company. We don't believe a word out of those those plumped-up lips of hers!

The teen is clearly on a kick to get people to believe she hasn't had had any work done. Earlier today, Kylie wrote a new post on her website in which she denied having gone under the knife (despite already admitting to having lip fillers). Kylie wrote, “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. I swear there are things you can do to work on problem areas without having to think about plastic surgery."

Umm Kylie -- have you looked at what your nose used to look like and what it looks like now? Because we have!

Of course, she did also write, “Never say never.”
