Selena Gomez is a different person since rekindling her romance with Justin Bieber, a new report claims. According to Radar Online, sources close to the couple said that the "Stars Dance" singer is "acting a little brainwashed" by Bieber and doesn't "challenge a thing Justin says."

"There was a time not long ago where they were fighting and arguing about their relationship, but now she's like a robot and completely in his thrall," the source told Radar.

Reportedly her family and friends have been urging Gomez to split from the "Boyfriend" singer but she refuses. The two have dated off and on for years and recently rekindled their romance earlier this year.

"Whatever he did to keep her from moving on from the relationship worked a little bit too well, because it's like she's a completely different person," the source continued.

The 21-year-old songstress recently fired her parents as her managers and there's been some speculation that Bieber could have something to do with it. TMZ broke the news that the former Disney star surprised Mandy and Brian Teefy last month by telling them that they were permanently relieved of their duties.

Reportedly she told her parents that she felt like she had outgrown them and wanted to be managed by someone who had more experience representing A-list celebrities. According to a report by Hollywood Life, Gomez is strongly considering having Kris Jenner or Scooter Braun represent her.

Braun also represents Bieber.

"Both Justin and the Jenner sisters have given their best pitches and Selena is highly considering working with either Scooter or Kris," the source said. "One thing that is good out of this situation is that she's really taking her time in making the decision. But both of them definitely have first dibs."

There were reports that she was leaning more towards Braun so she could be closer to her on-again, off-again boyfriend.
