Breaking News: Justin Bieber Tried to ‘Make Peace’ With Selena Gomez and Benny Blanco but Thinks They’re ‘Immature’…see more

An insider exclusively tells In Touch the “Sorry” singer, 30, is rolling his eyes big time about Selena and Benny’s long-term prospects.

“Justin is pretty offended by the fact that Benny totally cut him out of his life when he got together with Selena,” says the source.

“They used to be great friends, so it came as a huge shock, especially since Justin would love nothing more than to put all the bad blood with Selena behind him.” But it looks like Selena has moved on — big time!

In a photo posted to her Instagram Story on August 8, the Wizards of Waverly Place star, 32, used an emoji to cover up the ring finger on her left hand.

She took the shot in a bathroom mirror, showing off the one-shouldered dress she was wearing. Benny, 36, was in the background, facing away from the camera.

As Selena and Benny keep fueling rumors that they are engaged, Justin “can’t believe that it’s still carrying on and that Benny is playing into it,” says the source. “He would have expected a lot more from him.”
