After constant speculation on Kendall Jenner and Harry Styles being in a relationship, it now looks like the alleged couple have broken up.

Is Harry Styles Gay?

On Sunday, Hollywood Life reported that the One Direction band member and the Keeping Up With the Kardashians star have called it quits after three months of dating. A source revealed that the reason for ending the relationship was because they were just being young and wild.

"It was only a matter of time," the source reportedly said. "When they hung out with each other, they were just being young and having a good time."

It looks like the two stars will have a lot going on in their lives with Styles going on tour and Jenner working on her fashion projects and reality series.

"They both knew it had an expiration date with their schedules so they didn't fall hard into something more serious," the source added.

Even though it appears that they didn't fall too hard for each other, the insider revealed that Styles is probably handling it better than Jenner.

"Mostly Harry wasn't ever in it for the long haul," the insider said. "Kendall had a gleam of hope, but she wasn't his dream girl and his schedule was his out, he could have let it continue, but it was his decision to move on."

While the two stars appear to begin moving on with their lives, the source revealed that one day there might be hope for them getting back together someday.

"The way they left it opens things up for future hookups," the source said. "So it's over for now, but we'll see what happens after the tour."
