Kris and Caitlyn Jenner's daughters shared the hilarious videos on Kylie's personal account. They stuck out their tongues, smacked each other's hands and pretended to go in for a kiss on the lips.
At one point, Kendall (blink and you'll miss it!) slapped Kylie's chest with her hands three times and twerked like crazy à la Miley Cyrus.
"unrehearsed. no no @kyliejenner," the model, 20, captioned a clip via Instagram.
The siblings appeared to be at a party with several pals at the time. Kendall — who was spotted in St. Bart's with her ex Harry Styles over New Year's Eve — wore an off-the-shoulder top and Yeezus hat. Kylie, 18, cut loose in a tight long-sleeve top and later accessorized with a gold crown.
