Mariah Carey Accused of Cheating as More Ugly Relationship Details Emerge

Mariah Carey Is 'Not Sure' if She'll Stay with James Packer, Says Rep
Things may not be over for Mariah Carey and James Packer just yet...

As we previously reported, Mariah Carey and Aussie billionaire James Packer’s relationship hit a seriously rocky patch following a bitter fight in Greece. In fact, it was revealed that the renowned songstress is reportedly not sure she can go through with the wedding. Now, it appears Carey might have struck up an, ahem, relationship with one of her backup dancers.

“James was not in the right mind for months. Mariah was in essence an abandoned woman,” a source revealed to E! News. “While in Vegas, she turned to and developed a close relationship with Brian Tanaka [sic].”

The source went on to explain that Carey needed comfort after her fiancé began acting erratically, and she found it with Tanaka.

“James is not in a mentally healthy place right now and he has not been present for her,” the insider said. “Unfortunately, his absence and behavior was not a good situation for her, so she had to leave him.”

Just how different has Packer become in recent days? According to a source with TMZ, he appeared “mentally unstable” and even “violent.” However, Packer’s team since denied the claims of erratic behavior and called the allegations “simply untrue.”

Are they going to try and make it work, or is this high-profile romance at an end? Stay tuned for more details on this breaking story.
