“Is she getting married,” asked one follower on the image, while others asked if the ring was from her on and off boyfriend Tyga.

Earlier this week, Jenner and Tyga, who recently got back together after calling it quits, were spotted strolling through Los Angeles International Airport holding hands and exchanging kisses before flying to London.
