If there is a winner of the "bottle cap challenge" then Kendall Jenner gets the gold medal.
Jenner on the other hand took the "bottle cap challenge" to an entirely new level. She did it while in a thong and on a jet ski.
She captioned the video, "you asked for it @haileybieber ..."
She tagged Hailey Bieber since she was the one who challenged Jenner.
Is there anyone who did it better?
