Kendall Jenner Can't Keep It Together When Kylie Talks About the Time She "Sh*t Herself"

Kendall and Kylie Jenner were laughing so hard they could barely speak when they shared their most embarrassing moments with Cosmopolitan. The Kardashian-Jenners cover the magazine's November issue, and in a hilarious video, the group dives into some of their most awkward moments ever. While Kylie shyly mentions the time she "sh*t herself" when she was younger, Kris Jenner revealed what happened when she and her ex joined the mile-high club. "We had sex in the bathroom, and we came out, and nobody said anything," she said, adding, "At the end of the flight, the flight attendants got on the microphone and congratulated us with a bottle of Champagne and told the entire flight with about 300 people on board."
