Is Selena Gomez done with Justin Bieber? A new report says Bieber may have contributed to Gomez's recent decision to go to rehab.

Gomez took a hiatus from the spotlight earlier this year to deal with mental health issues stemming from lupus. She also entered a treatment facility.

 "I’ve discovered that anxiety, panic attacks and depression can be side effects of lupus, which can present their own challenges," she said at the time. "I want to be proactive and focus on maintaining my health and happiness and have decided that the best way forward is to take some time off."

But fans are wondering if Gomez's depression and anxiety weren't just because of lupus. It's safe to say that Bieber also caused plenty of stress in her life. His antics took a toll on their relationship and reportedly led to tension with her friends like Demi Lovato and Taylor Swift.

And just a few weeks before her hiatus, Gomez got into a social media feud with her ex. Earlier in August, Bieber claimed he was going to make his Instagram private because of fan backlash against his then-girlfriend Sofia Richie. Gomez then shot back that Bieber should just keep photos with Richie off of social media. She also reportedly accused him of cheating, while Bieber said Gomez was just using him for attention.

It's not clear if this incident convinced Gomez to go on hiatus and enter rehab. But it's possible this is what pushed her over the edge. Sources now say that Bieber contributed to her emotional struggles.

"While Selena does suffer from lupus and other health issues, that's not the reason she went to rehab," a source said. "Her biggest addiction is Justin."

The insider added that Gomez changed when she was dating Bieber. "She became a different person around him," the source continued. "She was extremely jealous and possessive and felt like she had to keep up with him to keep him. So she would drink and smoke, and then she got into weed and partying."

But Gomez finally decided she had enough. She rejected his most recent advances in March. And over the past few months, she has focused more on herself. 

So perhaps it's no surprise that Gomez is doing better now that she has moved on from Bieber. She looked happy and healthy when she made her return at the American Music Awards last month. And she reportedly just signed a $10 million contract with Coach!
