"The most embarrassing moment for me was when I was with Bruce on a commercial airliner in first class," Kris tells Cosmopolitan in a behind-the-scenes video from her family's cover shoot.
"We joined the mile-high club and we felt we got away with it. We had sex in the bathroom and we came out and nobody said anything."

But, as the couple soon found out, their little rendezvous did NOT go unnoticed.
“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!'" the 59-year-old reveals.
“I could not squish down in my seat low enough. I was mortified."
