It seems Harry Styles and former fling Kendall Jenner might rekindle their romance.

According to HollywoodLife, the One Direction lothario and the "Keeping Up with the Kardashians" star, who split after just three months of dating back in 2013, have been "talking and texting again," although they are "just friends" for now.

"The conversations can be flirty as Harry can't help himself," a source revealed, adding that the two have been planning to go out with their friends when the British singer is in Los Angeles and available.

Justin Bieber, who is rumored to be in a "friends with benefits" relationship with Jenner, sees Styles as a threat. And this supposedly extends professionally. The source adds that Bieber does not want to build any sort of friendship with Styles. 

"Whenever Harry calls her, Justin gives Kendall an incredibly hard time," the source said. "One of the times Harry called Kendall, Justin grabbed the phone and answered it. He and Harry talked for a minute in a fake nice kind of way, but it was obvious Justin was just doing it to mark his territory."

The source added that the model actually likes that the "Boyfriend" singer is "jealous."

Another source told HollywoodLife that Bieber is currently hooking up with both Jenner and her close pal, Hailey Baldwin. However, he does not want to be in a committed relationship with either one of them.

The source also claimed that the love triangle initially caused tension between the two girls, but they eventually got over it completely.

"Feelings are just off limits. Justin is not down for any drama," the source explained. "He likes these girls because they let him be whoever he wants to be with whoever he wants."
