Mariah Carey and James Packer not speaking after fight

Mariah Carey‘s rep has confirmed that her relationship with James Packer has been rocky following a fight in Greece just over a month ago.

Carey’s rep said in a statement to ET, “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. James is one of the most successful businessmen in the world. They are trying to work it out. Right now, they’re not sure if they will stay together. They are discussing it, and plan to release an official statement together about their future.”

TMZ reported that the couple were vacationing on his yacht at the time, and sources close to Carey claim Packer did “something really bad” involving her assistant. Mariah left the boat immediately and jetted back to LA.

A source close to Carey added to Page Six, “They’ve been going through a rocky time, but it is not because of her excessive spending. Mariah been working all the time and he’s been out of the country taking care of his own business. They had a fight in Greece, and it isn’t clear if they are going to work things out.

“James did not dump Mariah over money, nor her lavish spending. There’s no way this could be about excessive spending. Yes, she likes her hair and makeup done, and, of course she goes shopping, she might buy five pairs of Louboutins, but there’s no way her spending is excessive by his standards. He moves his icebreaker yacht from country to country on a whim, he regularly lends it to celebrities, if he wants pizza he moves it to Italy. He has a private jet, fully staffed houses in LA, Aspen, Argentina, and an island in Australia. He’s building another mega-yacht, and developing an island with Robert De Niro, and he has his movie deal with Warner Bros. All this wildly exceeds anything Mariah could spend on her wardrobe.

“This isn’t a typical relationship, they spend months apart. He’s a billionaire and she’s Mariah Carey, they both travel all over the world and try to meet regularly somewhere in the middle. But recently it has been hard, she has been touring and next month she goes to Mexico then Hawaii, and she’s resuming her Beacon dates in New York for Christmas.”

The source added that while they were “blindsided” by the report about their split, they had already agreed to “put their wedding on hold.”

A source close to Carey said of Packer, “James isn’t in the best space mentally, he’s kind of checked out, and that put a strain on their relationship. Something went down with Mariah’s assistant when they were on the boat in Greece. It wasn’t a violent incident, but it meant that Mariah had to leave. She left James on the boat and came home early. They haven’t spoken since the incident. They are broken up, and they don’t know if they’ll be able to get back together. Mariah is pretty bummed it didn’t work out, but she has got a lot of work to deal with at the moment, and she’s back in LA with the kids — they are her priority.”
