It's patently obvious what's happening here. Stella is salty at being ousted so is leaking these fake news reports to the press. Hello! What qualifies Bryan Tanaka to manage Mariah's music career?! Nothing, hence why he isn't. Mariah's delusional in a lot of ways but she's not stupid. Lastly, Stella left two minutes ago. Trust before that point Mariah was booked up until next Autumn. She's good. She's fulfilling her pre-arranged engagements while an appropriate replacement for Stella is found, for which there is no rush. All she needs is a personal assistant and someone to 'manage' her schedule, which is probably what Bryan is doing if he's indeed doing anything. Let's not forget he broke his leg on her tour.., he's probably still unable to dance effectively.
