The Problem singer signed to Scooter's roster in 2013, joining Justin Bieber and Carly Rae Jepsen, among others, and she went on to experience huge success with the music guru as her mentor.

However, Ariana and Scooter went their separate ways in February (16), with an insider insisting at the time rumours suggesting Bieber had something to do with the 23-year-old's decision were unfounded.

"Ariana always has and continues to support Justin," a source told U.S. news show Entertainment Tonight. "She did not think the relationship was working for her professionally anymore. It was time to move on.

"She thinks this is the best professional decision for her moving forward."

After Ariana parted ways with Scooter, her mother Joan and Untitled Entertainment's Stephanie Simon took over management duties, according to Billboard, but now she's back with Braun.

Ariana has previously spoken about her close relationship with Scooter, revealing she treated him as a father figure because she "barely" sees her own dad, Edward Butera, who split from her mum when she was a child.

"(Scooter)'s like a stepdad," she told Britain's Daily Telegraph newspaper in 2014.
