Selena Gomez revealed during a recent interview that her break up with Justin Bieber made her stronger, leaving many fans wondering if it saved her music career.

"I questioned the way I looked, acted, sang, and wrote. I started becoming very stale with my music, and I realized that I was doing things for other people," she said during an interview with Seventeen magazine.

"Then I turned 20, went through a really bad breakup, and realized I needed to pick up everything."

Selena Gomez has asked Justin Bieber to enroll in anger management classes in order for them to officially get back together, a source recently revealed, leaving many fans wondering if they may have broken up in the past over any form of domestic abuse.

However, Justin Bieber has never been formally accused of physically or mentally abusing his on-again off-again girlfriend.

"Selena has told him 'no romance without new manners', and insisted that he should take a course in anger management," a source told Yahoo OMG!

"Selena is an old fashioned southern girl from Texas and believes in manners and good behaviour. She's told Justin that he has to mend his ways if they are to start seeing each other regularly again."

Selena Gomez is worried sick about Justin Bieber after his police raid and it is reportedly affecting her lupus, HollywoodLife.com reports, leaving many fans wondering if they will slow down their relationship.

"Selena has been told repeatedly to avoid stress at all costs when it comes to her overall health," a source told the website.

"Lupus is triggered by stress and anxiety, and right now Selena is completely stressed about Justin and this whole egging nightmare. She's worried sick about him, but at the same time won't leave him. She's basically picking Justin over her own wellbeing."
