Justin Bieber, Selena Gomez Split Kendall Jenner Love Triangle Cheating Scandal- 'KUWTK' Star Comes Between Biebs & Gomez

It seems that  Kendall Jenner has once again found herself in the middle of Justin Bieber and Selena Gomez's increasingly toxic relationship. The Keeping Up With The Kardashian star — who is Bieber's bestie — feels that she can't hang out with the musician without making the former Disney star jealous. However, while Gomez and Bieber are still off in their on-again, off-again rollercoaster of a romance, Jenner still feels very conflicted whenever she hangs out with the "Boyfriend" superstar.

Kendall's sister, Kylie Jenner, took to her Instagram account over the weekend to post picture of herself hanging out with her sis and Justin at friend Hailey Baldwin's birthday celebration.

However it seems like the photo has stirred up some feeling in Selena, according to Radar Online.

While Selena knows that nothing happened between Kendall and Justin, the fact that the two were very close is something that Gomez was very uncomfortable with.

"Despite the face that people assume Justin and Kendall have hooked up, they have not. They are legit best friends and Selena knows this," a source told the news site.

"Selena initially thought that they were having an affair and told Justin to stay away from her," the insider added, saying "She eventually realized that was not going to happen though."

While the former couple are still not back together, a source is explaining that they do "talk and text every day."

However, it seems that Kendall feels really conflicted because she still feels like she is put in the middle between the two of them.

"Everyone who knows Kendall well knows that it really bothers her," the insider explained.

No news yet on whether or not Justin and Kendall's hangout hurt Selena's feelings.
