Kendall Jenner Admits She Was “Jealous” of Kylie Jenner Growing Up

Kendall Jenner Shares Where She Lost Her Virginity

Kendall Jenner is done keeping this secret.

The supermodel admitted that she was "jealous" of her younger sister Kylie Jenner during childhood because their parents, Kris Jenner and Caitlyn Jenner, were less strict on the Kylie Cosmetics mogul.

While recounting all their teenage antics, Kylie revealed that she had often smoked weed with friends at their parents' Hidden Hills home, where much of Keeping Up With the Kardashians was filmed. 

"Kylie had smoked weed before me," Kendall shared on the Oct. 30 episode of The Kardashians. "I was so mad at her. I was like, 'You're a degenerate!'"

However, the 29-year-old explained the likely cause behind her anger, saying in a confessional, "I was jealous. I was jealous that I didn’t have as much of a free spirit as her at the time."

But Kendall found a way to remedy the situation. As she put it, "I eventually smoked with them and then had the best time ever. Everything was great."

But that's not to say Kendall didn't get up to any shenanigans. After all, the 818 Tequila founder did lose her virginity as a teen.

"I lost my virginity in that room," she quipped to Kris while touring her childhood bedroom, before confessing that she actually did the deed for the first time at her then-partner's house because Kris, now 69, and Caitlyn, 75, "didn't care" about her whereabouts at the time.

"Not only did she not know, she really didn't give a f--k," Kendall joking added. "She was like, 'Oh, you're going out 'til Wednesday? Great. Never come back.'"

New episodes of The Kardashians drop every Thursday on Hulu.
