Ariana Grande Dumps Manager Scooter Braun After Bieber Incidents

Ariana Grande has "terminated" her relationship with manager Scooter Braun, multiple sources told RadarOnline.com.

An insider told RadarOnline.com, "I can confirm she's no longer working with Scooter Braun. She terminated the agreement."

Asked whether it was an amicable parting, the source said, "I don't want to get into the details, but she terminated the agreement. She does continue to be managed by Untitled."

Grande was signed to Braun's management in early 2013, and soon saw her career take off. But in recent months, she got caught up in bizarre incidents with the troubled teenybopper who was Braun's first discovery and is still managed by him, Bieber.

As RadarOnline.com reported, Bieber got a little too hands-on during an appearance at Grande's L.A. concert for the "Honeymoon Tour" last April. After pics of Bieber grasping an uncomfortable-looking Grande surfaced, her then-boyfriend, Big Sean, tweeted, "This kid is about to learn not to touch my girl like that. Beliebe that."

Grande and Big Sean split not long after.

Then just last month, Bieber, 21, posted a flirty comment on one of her Instagram videos, writing, "d**n Ariana u look so good."

While Grande, 22, didn't respond directly, she tweeted, "lol no … not today satan!!!! Gtg finish this music & live my cute, drama free life !!"
