Mariah Carey's rep address breakup rumors

Mariah Carey has not seen her fiance, James Packer, since they had a fight during their vacation in Greece last month, the singer’s rep tells ET.

“The fight was not because of any cheating allegations or excessive spending by Mariah,” the rep says, noting that Packer, a 49-year-old billionaire, is “one of the most successful businessmen in the world.”

“They are trying to work it out,” Carey’s rep continues. “Right now, they’re not sure if they will stay together.”

The rep says that the two plan to release an official statement after they’ve determined their future. 

However, Packer’s rep tells ET that this is all “simply untrue.”

On Sept. 22, Carey shared a “festive” photo of herself and Packer in Mykonos. The 46-year-old entertainer’s 5-year-old twins, Moroccan and Monroe, were also with the couple.

The two were first reported to be dating in June 2015, and Packer proposed to Carey in January with a 35-carat diamond ring. On Oct. 22, the mother of two was still wearing her ring at her Halloween party in Los Angeles, California, where she was joined by her ex-husband, Nick Cannon, and their twins.

In June, Carey told ET that it was her goal to be married by the end of the year, but said she has “a lot on [her] plate.” 

When ET caught up with Carey in August, she was still talking about her pending nuptials to Packer, and revealed a rule she had for her marriage. “It is important to have his-and-hers everything,” Carey said, adding that this pertained to yachts.
