“Selena has become more and more insecure because of the way Justin is with his fans,” said a source.

Sources say Sel is becoming increasingly jealous of her boyfriend's relationship with his female fans!

“Justin is a real flirt and loves the attention. While he tells Selena there’s nothing in it, she can’t help but feel upset about it and she told him so.”

Being jealous is not healthy, though it does sometimes happen! Sel doesn't want all the pressure and has confessed she never wanted to be a role model:

“I never really said I want to be a role model. But then when it happened I was so down for it,” she said.

“I’m human, I’m not perfect. I make mistakes all the time, but I guess my job is to keep those mistakes to myself, which I’m already fine doing and just try to be the best I can be for those kids.”
