And when we say act, we really mean her teeth!!
The young model took a break from clubbing with her sis and visited her trusty dentist Dr. Kevin Sands to get her chompers looked at, and they decided it was time for her to get braces!
But don't expect to see metal in Kendall's mouth anytime soon, because she opted to go with Invisalign instead!
"Kendall only needed a minor tweak to her teeth. She has pretty teeth and Invisalign is a great option. She's a model so Invisalign is perfect for her because she can take them on and off for shoots and it is invisible when she does wear them."
Minor tweak is right!
Seriously, how much more perfect can those pearly whites get??!
All we know is we're happy with the braces as long as it means we get to see more of those beautiful teeth!!
