Selena Gomez and Justin Bieber have not confirmed whether they are dating, but the singers have been spending a lot of time together fueling reports that the couple is back on.

Gomez has been constantly hanging out at Miami's Hit Factory recording studio, where Bieber is currently working on a new song with Madison Beer, and rumors swirling around suggest that Gomez is insecure about her on-again, off-again boyfriend's relationship with his young protégé.

Gomez' constant visit to the recording studio seems to be to check on Bieber, as a source close to the "Baby" singer revealed to HollywoodLife that at present the couple is not working together on any project.

"They are keeping their music separate and their relationship the main focus to work on," the source said.

The "Come and Get It" singer looked intoxicated and it is believed that she is once again turning to drugs and alcohol to battle her insecurity issues. Gomez had earlier checked into The Meadows to treat a combination of problems involving drugs and alcohol.

Meanwhile, Gomez recently decided to end her professional relationship with her parents by firing them as her managers. Mandy and Brian Teefey had been managing their daughter's career since 2007, and Gomez now feels that she has outgrown them.

While it was initially believed that Gomez's parents displeasure at their daughter getting back with Bieber was what got them fired, TMZ reported that the 21-year-old remains close to her parents.

She feels she has outgrown them and now wants someone with a lot of A-list clients to manage her career.

While nothing is immediately known about who her new manager is, the name of Scooter Braun, Bieber's manager, has been doing the rounds. Braun was at one point credited to getting Gomez back with Bieber, and has been pitched as the perfect person to manage both their careers.

Besides Bieber, the 32-year-old talent manager is associated with Psy, Ariana Grande and Cody Simpson among others.
