Jenner arrived at Nice airport on Thursday afternoon, wearing an all-grey ensemble as she walked past onlookers and photographers.
The TV personality sported a grey long-sleeve shirt with an asymmetric hem and matching grey leggings.
She styled the look with snakeskin heeled boots and black-rimmed sunglasses.
The appearance comes just days after she was hailed a “diva” by fans after she pushed an assistant out of the way on the Met Ball red carpet.
The 22-year-old was filmed trying to move the assistant as she attempted to nail the perfect shot for the cameras.
Jenner was posing in a white off the shoulder jumpsuit when a man working on the red carpet accidentally stepped back into her shot.
Clearly annoyed, Jenner pushed him aside before snapping back into a pose.
One Twitter user posted: “@KendallJenner really????? U didnt had to shove that guy just for the spotlight.. #MetGala2018 #METGala.”
Another tweeted: “who the f*** does Kendall think she is? Did yall see her push that security guy out of the way!?? #MetGala.”
