Justin Bieber had fans in a frenzy when he was spotted boarding a private jet with a mystery woman. Well, Beliebers, it looks like it may have been his friend and onetime rumored fling, Kendall Jenner! A fan photographed Justin, Kendall, and Patrick Schwarzenegger at Five Guys in Park City, UT chowing down on burgers before Christmas.

The photograph was reportedly taken on December 16, 2016, although it is only surfacing on fan accounts now.

Madison Beer had previously claimed that it was Kendall on the plane accompanying the pop star, after fans speculated that she was boarding the jet with Justin. She reportedly responded to Instagram comments by saying that she was in New York and it was "Kendall, not me" in the photographs.

Justin and Kendall have both repeatedly slammed rumors that they're romantically involved, saying that they're only good friends. The model did admit that he was more of a crush when she was growing up, but those days are long past. In 2014, she shut down all rumors by saying that he was just a longtime family friend. "Everybody loves to assume things, but no," she confessed at the time.

More recently, Justin has been linked to Sofia Richie and Kendall's BFF Hailey Baldwin. After denying the romance rumors for months, he shared a photo of them kissing on vacation during the holidays. It was quite the iconic smooch! However, the pop star insists that he's single and not looking for a relationship. He's simply spending time with his beloved friends.

Over the Christmas holidays, he hung out with his Shots app founder John Shahidi, watching his friend Rudy Mancuso's holiday special, The Keys of Christmas, on YouTube Red.

It looks like he's getting some much-needed rest and relaxation, and enjoying time with his loved ones. That sounds like a perfect holiday!
