Earlier reports claimed that Grande's decision to leave Braun's SB Management was partly caused by Bieber's attempts to flirt with her.
It is now being said that Grande's split from Braun was caused by a different reason, reported New York Post.
"It had nothing directly to do with Bieber, apart from he takes up a lot of Scooter's time. 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.
