Los Angeles-Justin Bieber apparently convinced Selena Gomez to fire parents Mandy and Brian Teefey as her managers.

The Baby singer was annoyed that Mandy and Brian kept blaming him for Selena’s problems, so he decided to take action.

“Mandy and Brian kept trying to persuade Selena that Justin’s a bad influence,” a source said. “Every time they heard that Selena had flown off to be with Justin, or that they were back together romantically, they’d immediately phone Selena to rant that her association with him was ruining her life and career. The calls always ended with Selena in tears - and mother and daughter not speaking for days at a time.

“Justin kept trying to convince Selena to dump her parents as managers - and it finally happened when Mandy told Selena she was concerned about her being dragged into Justin’s upcoming legal woes. Selena fired back, saying she was firing them both. Mandy and Brian didn’t take Selena seriously…until they read press reports confirming their termination. Now Justin’s telling pals he couldn’t be happier!”

Meanwhile, Selena’s parents want her in rehab and away from Justin. “They have always wanted her to take rehab seriously because she never has, and that would be the best thing for her. Her parents have been weak trying to make it happen, but are now trying to buckle down on it, even using her little sister to motivate her,” a source said.

“Her parents have begun using the fact that Selena will not be able to see her sister until she gets help and that seems to be working.”

“Selena’s main issues are depression and anxiety. She also has trouble sleeping, which makes everything worse. Her family, especially her mom, attributes many of her troubles to hanging out with the ‘wrong crowd’, Justin included.

 “Selena really wants to get better but isn’t sure what to do. Rehab is not something she thinks she needs. She thinks if she can just focus on her career and stay away from certain people, things will get better.

“She is not ready to let go of Justin though and he’s a main culprit in this whole mess. Her mom thinks rehab is the ticket because it will force her to stay away from Justin and get some much-needed rest and clarity.

“This is a very serious situation because all the stress has an impact on Selena’s health and aggravates the lupus and causes flare-ups. It’s no joke.”
