There’s huge drama in Mariah Carey’s camp, and several longtime employees have quit after clashing with the singer’s manager Stella Bulochnikov over the diva’s reality show.

Sources tell us her business manager Michael Kane, international publicist Connie Filippello, domestic publicist Chris Chambers, tour manager Michael Richardson, travel manager Gaylin Winkler and stylist Wilfredo Rosado, who designed her engagement ring, have all put in their walking papers.

“It seems as if Mariah has allowed a complete stranger, her new manager, to run her life, and others believe this woman is toxic. Seasoned executives in their profession don’t want to put up with her,” says a source close to the situation. “Stella is hard to work with. Mariah doesn’t understand what’s going on because Stella paints a different picture, so Mariah probably thinks it’s petty disagreements. These are not just random people who have left her. These are loyal people who have been around for years, some 20.”

Bulochnikov joined Carey as her manager last year after Hollywood filmmaker Brett Ratner introduced them. Sources tell us she has since brought in her family to help manage Carey and is very protective of who gets near her. She recently signed the diva on to do a series for the E! network.

“Stella has been using the TV platform to bad-mouth former people on the team on camera . . . She’s turning it into a reality show. She’s creating scenarios, and it’s not all about the shows in Vegas as she’s claimed. The show will definitely be trashy because it’s full of lies,” said the insider.

Bulochnikov even brought in her own lawyer and bookkeeper, which our source says has left Mariah’s staffers waiting to be paid.

“She hasn’t paid people, and they are threatening lawsuits,” said the source.

Bulochnikov called our reporter an “idiot” and told us to “f - - k off and lose my number” after Page Six ran a previous story about some on Carey’s team having doubts about the reality show. She did not return our calls for this story.
