The sources also claim that James Packer went crazy on one of Mariah's dancers, choreographer-Bryan Tanaka, whom he suspected was making moves on Mariah Carey.
Packer pulled Bryan into a room to have a discussion with him which turned out into a yelling matching between the two.
According to TMZ:
We're told Packer was so crazed he used his casino ties -- he owns several in Australia and Asia -- to get Tanaka banned from Caesar's Palace, where MC performs. This photo of Bryan was circulated to security. We're told Mariah didn't make a fuss because Bryan, who was nursing a knee injury, wasn't dancing. Mariah sources say she feared Packer. As we've reported, she thinks he's "mentally unstable."
