It didn't take long, however, before people noticed Kendall seemed to be rocking a brand new accessory - and we aren't talking about a new necklace or bracelet.
If you look really closely at the pics from the red carpet, it does look like Kendall has a silver ball on each side of her left nipple (right side of the photo).
We have to admit, we felt a little creeptastic searching through all of the red carpet photos and analyzing her nipple in every single pic, but we took one for the team...and it does look like she got one.
We kind of wondered if she was just messing with us to see if people would notice. TMZ's sources say it's the real deal, though.
Hey, Kendall is 19, she's allowed to do whatever she wants! Maybe she even got it the same night she got the world's smallest tattoo.
Aww...our little Kenny is all grown up!
