Back On? Kendall Attends Harry Styles' Concert After Idaho Getaway

Kendall Jenner has been getting a little too close to ex-flame Harry Styles, and fans are freaking out!

Just as RadarOnline.com exclusively reported the supermodel ditched boyfriend Ben Simmons to reunite with her boy band beau, Jenner, 22, was spotted cheering Styles, 24, on at his Los Angeles concert!

This Saturday, the stunner was pictured watching Styles perform for his California fans, four days after the two were rumored to have gone on a romantic Idaho retreat.

An eyewitness even said Jenner was "singing to all of his songs" and dancing to "Kiwi" and "The Chain."

RadarOnline.com readers know the two stars have been dating other people since they called it quits in 2016, but just last week, they were pictured hanging around the same Idaho resort and chatting with the same group of friends! Coincidence?
