Mariah Carey has been dumped by her billionaire fiancé, James Packer — who was sick of putting up with her “extravagant spending” and newfound love for reality TV, sources said.

The Australian casino mogul officially called it quits this week after being engaged to the singer for less than a year, according to Woman’s Day.

“It’s all over,” a family friend told the magazine.

“James had huge reservations about Mariah’s new reality TV show and the fact that she was willing to expose their lives to the world,” they said, adding that her spending sprees had also played a major role in the split.
