Mariah Carey Signed to JAY-Z's Rock Nation

Mariah Carey has reportedly signed to JAY-Z's Roc Nation after firing her former manager.

Page Six reports that Mariah is making serious moves after firing her former manager Stella Bulochnikov earlier this month.

“[Mariah’s] cleaning house. She is getting legitimate people, assistants, a lawyer, and Stella is not happy about it,” an "insider" reportedly told the publication.

Although there were previously reports that her boyfriend, Brian Tanaka, had taken over as her manager, he is reportedly her creative director.

“Previously, there were all kinds of people involved [in her career] and Mariah didn’t even know those people," the insider told Page Six. "She had to distance herself from all that and she’s now cleaning house."
