It's pretty obvious he still cares about his ex.

Justin Bieber was visibly emotional and crying in the car with Hailey Baldwin, after news broke that his ex Selena Gomez was in treatment after suffering a mental breakdown. It looks like he's about to have a breakdown of his own!

The Biebs has reportedly been struggling with his own demons in recent months, and he's finding it difficult to navigate his fame.

"Justin has become a recluse and a changed person. He has no interest in being a celebrity and an artist. He has withdrawn again, much like he did a couple years ago. He started recording music, but just stopped," a source dished to Us Weekly.

"[Justin] has a lot of stuff going on his head. He’s not OK. He has so much going for him but he doesn’t feel whole," the source added.

Even though he ran off and got married, JB will always hold a soft spot for the "Come & Get It" songstress.

"Justin will always care about Selena. It’s hard for him to hear that she isn’t doing well. They have both had their separate struggles over the years and Justin was always very sympathetic to Selena’s. He wants the best for Selena. He wants her to be happy and healthy," an insider told People.

Something tells us we haven't seen the last of Jelena... we even asked Justin as he and Hailey went to lunch in the Valley, on Friday, if he's concerned about his ex ...
