Carey's spokesperson also shot down rumours that Packer dumped the singer due to excessive spending, saying they are constantly trying to make it happen since they had an argument during their vacation last month, reported Entertainment Tonight.
"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," the rep said.
The two were first reported to be dating in June 2015, and Packer proposed to Carey in January with a diamond ring.
