Kendall Jenner has admitted she’s a "stoner" after saying that she smokes marijuana.

The Keeping Up With The Kardashians star, 24, opened up about her cannabis habit after being outed by Kourtney in a podcast.

Marijuana use is legal in California, where supermodel Kendall lives, and in an episode of Sibling Rivalry with Kate Hudson and Oliver Hudson, which was recorded in January, Kendall opened up about her cannabis use, something she had previously kept private.

Kendall paired up with half-sister Kourtney on the show, and the pair were given a series of quick-fire questions.

Oliver asked the two sisters: "If future was a stoner [in your family] who would it be?"

Without hesitation, Kourtney quickly answered: "Kendall."

Not disagreeing, Kendall admitted: "I am a stoner."

"No one knows that, so that’s the first time I’ve ever really said anything out there."

Kendall and Kourtney were then asked who was the most laid-back of the Kardashian-Jenner clan, and they both agreed that it was the youngest of the siblings – Kylie Jenner.

Kourtney shared: “Kylie is very non-judgemental.”

Kendall did not further expand on her drug use during the chat.

Kendall, who previously dated Harry Styles, is reportedly dating American basketball player Devin Booker, 23.

Recent snaps obtained by The Sun showed the model and the Phoenix Suns shoot guard enjoying a PDA session on a beach in Malibu.

In April, a source told TMZ that Kendall is surrounding herself with a small group of quarantine buddies amid the Covid-19 pandemic, and Devin is one of them.

The source claimed: "Kendall and friends have a small social circle amongst the group, who have been following the same social distancing and physical distancing guidelines. Devin is a friend and is part of the small group," the source said. "They took a road trip for some much-needed air."
