Kendall Jenner arrived at Los Angeles International Airport on Tuesday to catch a flight out of town, and though she didn't appear to be in the best mood, she looked amazing!

We're not sure what's eating the 19-year-old supermodel, especially since she spent the whole weekend with her NBA star beau, Jordan Clarkson. After the lovebirds spent Sunday hanging out at her new $6.5 million Hollywood Hills home, they went to the Beverly Hills Hotel, and the following day they hit Nobu in Malibu for a Fourth of July party.

Kendall has been extremely quiet about her romance with Jordan, but given how much they've been hanging out over the last few days, we have a feeling she'll be a bit more receptive to sharing a few snapshots of the two on social media. I mean, she'll never go full Kylie, but she's been dating Jordan long enough, it's about time for a couple selfie, right?!
