During her interview, Kendall opened up about how Devin really clicks with her family, especially her 18 nieces and nephews.

“He loves them,” Kendall shared, adding that he and Kylie Jenner‘s daughter, “Stormi have an amazing relationship. She has the biggest crush on him, and I’m jealous sometimes. I’m like, ‘Stop—can you guys not?’”

Kendall also opened up about how her competitive streak comes out around him.

She even shared a story about trying to show off her basketball skills, only to see him get really serious about the game.

“We were playing in the pool, and he just took it way too seriously—as did I, by the way,” Kendall recalled about their water-basketball hoop game. “I had the ball, and he was guarding me, and it was a whole thing.”

She added, “He actually ended up cutting my hand open a little bit with his nail because he took it a little too seriously.”

However, it’s all healed up now: “It’s pretty much healed now, so you cant really see it, but it was a big gash, and it bothered me for like two weeks.”

Over the weekend, Kendall and Devin were spotted grabbing a bite to eat together in NYC.
