Kendall Jenner implied in a new interview that her mom Kris Jenner knew of Caitlyn Jenner's desire to transition since their "third date."

"My mom knew," she told Vogue. "She knew since their third date."

When Caitlyn Jenner graced the cover of Vanity Fair, the accompanying interview claimed Kris Jenner was well aware of the Olympian's struggle, however Kris Jenner later told the Hollywood Reporter she was in the dark. 

"Nobody mentioned a gender issue," she claimed.  

Kendall Jenner's statements seem to contradict Kris Jenner's claims. 

The 20-year-old admitted it was difficult to watch her dad become a woman.

"Obviously it’s strange to having your dad, who was so male, completely reverse. It is definitely a gnarly experience."

But the transition wasn't a total shock as the model had witnessed the Olympian dressing in women's clothing at a young age.

"My whole life we would, like, catch her, and we would be like, 'What is going on here?' I think we know, but do we? At one point, Kylie and I thought he was cheating on my mom, because he had makeup and nail polish."

The reality star found "squishy boob things" and wigs around the house. Eventually, she caught Jenner dressed as a woman in the early morning when no one was around.

"And then one time I actually ran into her. In this house. She had no idea. She would wake up really early just so she could dress up and move around the house and get that little kick for the morning, and then go back to being Bruce -- take us to school, totally normal."

She added, "That was the first time I had ever seen her."
