According to reports, two of Scooter Braun’s biggest clients have left him after a long-running dispute over Taylor Swift’s master recordings.

Neither Ariana Grande nor Demi Lovato are currently working with their manager, according to Billboard.

In May, the Colombian star J Balvin left Braun to join Roc Nation’s management team.

The reports that Justin Bieber has also split from Braun have been denied.

According to his website, Braun has worked with David Guetta, Black Eyed Peas, Ava Max, Carly Rae Jepsen, and Quavo.

Before signing with Def Jam Records, he promoted parties and events in Atlanta as a teenager.

His big break came in 2008, when he spotted a 12-year-old Bieber singing on YouTube and recognized his star potential.

His school board members helped him contact Bieber’s mother, and he signed him to a record label he had formed with Usher.

He quickly became one of pop’s biggest stars, and Braun has guided his career through several ups and downs, including a string of arrests for vandalism, dangerous driving, and assault in 2013-14.

By arranging a Comedy Central “roast” that showcased his humility, coupled with a stretch of singles, including Sorry and Love Yourself, he eventually helped the singer rehabilitate his image.

Since signing with Braun in 2013, Grande has released six albums, five of which have topped the US Billboard charts.

As a result of the Manchester bombing, Braun organized the One Love benefit concert, which raised millions of pounds for the victims’ families.

Currently, Grande is working on a movie adaptation of the Broadway musical Wicked, which she has not released since 2020’s Positions.

In addition to her management ties with Braun, it is unclear whether she has severed all ties with him.

Lovato started working with Braun in 2019, saying: “Dreams came true for me. I now have a new manager. And not just any manager. The one and only Scooter Braun.”

They split amicably, according to an unnamed source. On Sunday, Braun posted a birthday message to Lovato on his Instagram story, calling her “one of the kindest souls in the world”.

Probably best known for his feud with Taylor Swift, the manager bought her former record label Big Machine for $300 million (£227 million) in 2019.

This meant he controlled Swift’s first six albums, which she saw as an act of aggression that “stripped me of my life’s work”.
