Mariah Carey was "devastated" when she split from James Packer.

The 'We Belong Together' hitmaker was reportedly left "blindsided" when the Australian billionaire called off their engagement.
A source said: "The split has been devastating for Mariah. She loved James and was planning to marry him ... She made life changes for this man to prepare for their future as husband and wife, even relocating to Los Angeles, at James' request, so he could be closer to his children. Everything she has done over the past year is to prove how fully committed she is to their life together. She really wanted this to work. And then, completely out of the blue, it imploded."
Things started to go down hill for the 46-year-old singer - who has five-year-old twins Moroccan and Monroe with her ex-husband Nick Cannon - and James when they were in Greece.
An insider added: "It started in Greece [with] some sort of outburst [from James] which everyone heard. [He told her,] I don't know if I can do this. I can barely take care of my own children."
The former couple were meant to meet up in Los Angeles to "talk through everything as adults" but they called it off when Mariah found out James had decided to end their relationship.
A source told E! News: "Mariah and James never met up after that. And they haven't spoken. The way the split news was handled was incredibly upsetting to her."
Meanwhile, Mariah's spokesperson previously confirmed the pair are "trying to work things out".
They said in a statement: "Mariah and James had a fight in Greece, and have not seen each other since. [The fight was not due to] any cheating allegations or excessive spending. They are trying to work it out. Right now, they're not sure if they will stay together. They are discussing it."
