The 59-year-old matriarch made the stunning admission during her latest interview for Cosmopolitan's 50th anniversary issue, the cover of which she stars on alongside her five famous daughters.

"The most embarrassing moment for me was when I was with [Caitlyn] on a commercial airliner in first class," she told the magazine. "We joined the Mile High Club and we felt we got away with it," she says, cringing at the memory.

"We had sex in the bathroom and we came out and nobody said anything. At the end of the flight, the flight attendant got on the microphone. 'Congratulations, Mr. and Mrs. Jenner! You've just joined the Mile High Club. We're so proud of you, and we decided to give you a bottle of champagne! Yay!' I could not squish down in my seat low enough. I was mortified!"

Despite the embarrassing story, Jenner's daughters Kim Kardashian, Khloe Kardashian, Kourtney Kardashian, Kendall Jenner, and Kylie Jenner appeared to be delighted to be invited to star on the front cover of the anniversary magazine, alongside a headline dubbing them "America's First Family."

"We're so excited to reveal our November @Cosmopolitan cover in honor of Cosmo’s 50th birthday!" an excited Khloe wrote as she shared the first pictures from the cover shoot via Instagram. "Make sure to follow @Cosmopolitan for behind-the-scenes photos from the shoot and look for the issue everywhere in stores next week!"
