Kim Kardashian has opened up about discovering her stepfather Caitlyn Jenner’s “dark dark secret” aged 22, as she covers iconic Rolling Stone magazine.

Kim admitted she first spotted the former Olympian cross-dressing when she was 22-years-old, and described feeling nervous at the time that she would “come after her”.

“I was shaking,” she tells the mag. “I didn’t know if I’d just found out his deepest, darkest secret, and he was going to come after me.”

Her stepfather called her on the phone half an hour later, and said: “One day, I’ll talk to you about this. Until then, don’t tell a soul,” before finally having that talk eight years later.

On her brother Rob, Kim admitted she believes he spends most of his time “smoking weed and drinking beer”.

“It’s not that mysterious, what’s happening with Rob,” she told the mag. “He has gained weight. He feels uncomfortable being on the show, and that’s OK.

“Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes.”
