There have been many theories regarding the famous Selena Gomez Instagram meltdown of last week but now it seems the singer may have had better cause for cutting ties with her online friends than anyone could've imagined.

A new report claims Selena discovered sexy texts on Justin Bieber's phone sent by none other than her former BFF Kylie Jenner.

Justin Bieber: Cheating With BOTH Jenners?

She naturally cut ties with the Jenner sisters online that same day and shortly after deleted everyone from her account.

This is not the first report of Bieber cheating with Kylie, but it seems that Selena was happy to ignore the initial rumors.

Now that she's been  confronted with hard evidence, however, Selena has apparently made the decision to cut Kylie, Kendall, and Justin out of her life for good.

Selena reportedly discovered the illicit texts while she was partying with the Jenners at Coachella.

Sources say she immediately fled home and began severing all digital ties to the famous sisters.

This latest falling out between Selena and Justin may help explain not only why she ended her online friendship with Kylie, but also why Selena and Orlando Bloom have been spending so much time together lately.

Meanwhile, a new report claims that Justin was spotted in NYC this week hanging out with Kendall Jenner, not Kylie.

Could the Biebs be getting intimate with both Jenner sisters?! No wonder Selena's furious!
