Wearing a beautiful one-shoulder Marni gown with a dramatic train, the 21-year-old model stole the spotlight on the red carpet, and eagle-eyed fans noticed a minor change in her appearance.
Kendall is now rocking a gold cross cap on her tooth, which you can see up close in the video below!
Possibly inspired by her new rapper boyfriend A$AP Rocky, the KUWTK star brought a little edge to her ensemble with the addition to her smile.
However, this is not the first time Kendall has rocked "grills." Earlier this year, she stepped out at London Fashion Week with two gold teeth, and fans were definitely divided over the dental upgrade.
"Kendall wasn't daring for that gold tooth she just been hanging out with rappers," one Twitter user commented while another added, "tell Kendall Jenner that those silver/gold teeth need to be taken out ASAP and that 'junkie' isn't a good look."
