Mariah Carey’s engagement to millionaire James Packer has crumbled in the past weeks but it seems the American singer did not know about the impending split and was "blindsided" by the eventual separation. It seems the mum-of-two read about being dumped in Woman’s Day Australia - the magazine that broke the news on Thursday 27 October.

The source said: "Mariah was totally blindsided by James. She read the news in Woman’s Day Australia that James had dumped her.

"Mariah knew they were having problems but all relationships have issues - it wasn’t the kind of thing she thought she’d read in the paper that she got dumped... She was devastated. She was shocked."

The singer, who was previously married to Nick Cannon, confirmed the split through a rep.

The representative said: "Mariah and James had a fight in Greece and have not seen each other since.

"The fight was not because of any cheating allegations or excessive spending by Mariah.

"They are trying to work it out. Right now, they’re not sure if they will stay together."
