Selena Gomez recently went public with Samuel Krost, and her ex isn't happy about it.

There's No Denying Selena Gomez & Samuel Krost Are A Couple Now!

According to a new report, Justin Bieber is doing his best to steer clear of the steady stream of photos of Gomez and Krost, which continue to hit the web weeks after their romance reveal.

“[Justin] is trying to avoid all the Samuel Krost stuff because it makes him jealous,” the insider told Hollywood Life on Wednesday. “He hates that Selena has finally figured him out. He took her for granted and it is now coming back to haunt him.”

Although Gomez and Bieber kept in touch for years after their split, and were spotted together in Los Angeles just one month ago (when Bieber serenaded Gomez at a local hotel), the source claimed Gomez is no longer responding to his phone calls and text messages.

“It really is screwing with his head because he is not in the drivers seat with her,” the insider continued to tell us. “It really is something he isn’t familiar with and he is trying to figure out if he should let her go for good or not."

While Bieber may be disappointed in the love life of Gomez, he appears to have a lot going on in his own life. In addition to rumors regarding his relationship with Kourtney Kardashian, Bieber has been linked to both Hailey Baldwin and Sarah Jeffery in recent weeks.
