'Like who hasn't? Everyone has faked 'The Big O' at some point. I feel like you're like, "Oh my God. What have I gotten myself into?" Or like, "Dude, hurry it up. We've got work in the morning.'"
'Kendall and Kylie, earmuffs!' Jenner yelled to her 17 and 15-year-old daughters in the crowd.
'They don't know what "The Big O' is," Kardashian said. 'It's the Oprah show,' her mother added.
But Kris took it further when she revealed that she and the younger girls father, Bruce Jenner had joined the Mile High Club.
She said: 'We decided intentionally to join the Mile High Club, we thought we were so sneaky . . . So we come back to our seats and we were like two Cheshire Cats - we thought we got away with something.'
