Kris said she was embarrassed when a flight attendant told passengers on board that she and her ex boo, Bruce Jenner now Caitlyn Jenner had sex.
According to the reality TV star,
“The most embarrassing moment was when I was with [Caitlyn] on a commercial airliner in first class. We joined the Mile High Club and felt we got away with it. 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.
