Ariana Grande has parted ways with her longtime manager Scooter Braun. Initial report by Radar Online suggested that Justin Bieber, another famous face represented by Braun, was partly responsible for the former Nickelodeon star's departure from SB Management.

The site didn't explain what exactly Bieber had done that prompted Grande to make the decision, but they noted that the Canadian heartthrob had several times tried to flirt with her. Last year, he got a little too handsy with her when he made a surprise appearance at one of her concerts. He's recently also made a flirty comment on one of her Instagram posts. Grande allegedly responded to it on Twitter, writing, "lol no ... not today satan!!!! Gtg finish this music & live my cute, drama free life !!"

However, newer reports said that Grande's split from Braun was caused by a different reason. "It had nothing directly to do with Bieber, apart from he takes up a lot of Scooter's time," a source stated as cited by Page Six. "Ariana needs someone who can pay more attention to her as a manager."

Braun, who also represents the likes of Carly Rae Jepsen, Tori Kelly and Cody Simpson, began managing Grande in 2013. The "Focus" singer will now continue to work with Untitled Entertainment and her other manager, Stephanie Simon.
