Justin Bieber VS Niall Horan: ‘Sorry’ Singer Furious With One Direction Member For Stealing Selena Gomez; Ex-Couple Just Using Kourtney Kardashian and Niall To Make Each Other Jealous?

There were swirling reports that Justin Bieber and Selena Gomez are trying to rekindle an old flame. However, to all Jelena fans' dismay, the 23-year-old Disney alum was spotted getting cozy with One Direction singer Niall Horan few days after the news broke.

Now, the latest catch is Justin is seething that Niall stole his ex Selena from right under his nose. The two singing heartthrobs used to be friends but, with the brewing Siall romance, their friendship might soon be over.

"Justin is still furious with Niall for going behind his back and stealing Selena from him. That's how he sees it. At first he didn't want to contact Niall in case it was just like a short-lived fling, which still is not cool with Justin," an unnamed source told The Hollywood Life. "But now that Niall and Selena seem to have a serious relationship, Justin wants to see his so-called friend in person and confront him."

The insider added that Justin has been pressing the "Little Things" hitmaker for answers. However, there is no way Niall is responding the "Sorry" singer. "He texted him a couple of messages but Niall isn't engaging, per Selena's instructions," the same source claimed.

To recall, the Selena-Niall reports sparked in the midst of Justin-Kourtney Kardashian "hook-up" news which dominated the romance headlines for a couple of weeks. International Design Times reported that the Canadian pop superstar and "Keeping Up With The Kardashian" star have been spotted frequently together.

According to sources, Justin and Kourtney started "hooking up" after the latter's split from longtime boyfriend Scott Disick. While some believe that this is just the reality star's tactic to make her former beau jealous, some said the "What Do You Mean?" singer has been bragging his escapades with the 36-year-old mom-of-three to his close friends.

If Kourtney is using Justin to make Scott jealous, then it is also possible that Selena is using Niall to make her former sweetheart green-eyed. Whether or not this view is true, no one can confirm yet.
