Kim Kardashian took to her new website to share some more insight into the secret she kept about Caitlyn Jenner for over a decade, way before Jenner transitioned to become a woman.

She has been open about catching a then-Bruce Jenner in women’s clothes, but she now says she wouldn’t have believed it all if it wasn’t for a conversation she heard between her late father, Robert Kardashian, and some friends.

"Had I not overheard my dad and his friends discussing rumors that Bruce would dress up as a woman years before (when I was about 11 years old), I never would have believed what I was seeing," she wrote.

"I thought my dad was jealous of my mom's new husband, that he was joking with his friends on the phone, but suddenly I knew it was all true,” she continued.

She admitted to Googling segments from The Oprah Winfrey Show to better understand why her stepdad was dressed up this way, and also admitted she just “assumed he was a cross-dresser, not transgender."
