Our Mariah sources tell us, “she had to leave him” and he hasn’t been “present for her” in a couple of months. They call James “mentally unstable.”
Even more serious … the sources say the last straw for the relationship was that he got “violent” a month ago on a yacht in Greece.
TMZ broke the story … Mariah claimed Packer was really terrible to her assistant on the boat, and that sent her packing.
Packer’s camp tells TMZ … Mariah’s allegations are “simply untrue.”
