Phoenix Suns star Devin Booker and now-long-time girlfriend Kendall Jenner are quickly emerging as one of the NBA's most high-profile power couples. It clearly has a lot to do with Jenner's immense popularity throughout the globe, while Booker is no doubt one of the brightest young stars in the league right now.

Jenner recently made an appearance on The Tonight Show with Jimmy Fallon where she shared a few tidbits about their relationship. One revelation the 25-year-old supermodel made was about Booker's relationship with his niece, Stormi (the daughter of her sister Kylie Jenner and rapper Travis Scott). Apparently, Kylie can't help but get “jealous” sometimes over how close Devin is with Stormi:

“[Booker] loves them,” Jenner said, via Megan Armstrong of Yardbreaker. “Him and Stormi have an amazing relationship. She has the biggest crush on him, and I'm like, jealous sometimes. I'm like, stop. Can you guys not?”

Kendall Jenner was clearly joking around, though, and she absolutely adores how Booker is so good with kids. Is this a sign of things to come? I mean they've been together for quite some time now and they seem to be the perfect couple. Now that we know how good the Suns star is with kids then perhaps a couple of their own might be on the way sometime in the near future? Jenner seems to be amenable to the idea.

What cannot be denied, however, is how Devin Booker is clearly winning both on and off the court.
