Kendall Jenner jetted out of LAX on Thursday, and the supermodel kept her head down as she made her way in to the terminal. Guess she wasn't in the mood to answer questions about her on again/off again beau Harry Styles!

While Kendall and Harry (can we just call them Hendall?) were spotted together last month, we haven't gotten an update on the couple in nearly two weeks, and a source at Now magazine claims that their hookup is over as the One Direction hottie "wasn't looking for anything serious."

"Kendall is kicking herself for getting sucked in again by Harry. She feels like such a fool," a source told the mag. "It's true that they never talked specifically about the relationship, but she never would have hooked up with him so publicly if she knew it was just going to stay casual. She caused huge drama among her friends and really upset Taylor because they made a pact to never give Harry the time of day again." Yikes!
