Mariah Carey is believed to be heartbroken yet again after her fiancé James Packer reportedly dumped her due to her “extravagant” spending.

The billionaire casino businessman, 48, is said to have called time on his relationship with the 46-year-old Hero singer because of her over the top spending habits, while her upcoming reality television show Mariah’s World was also believed to be a bone of contention.

A family friend is reported to have told Australian magazine Woman’s Day: “It’s all over. 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.”

According to reports, Carey - who is worth in the region of $500million - is keeping the $10million diamond engagement ring.

The pair met in 2015, and announced their engagement in January.

Carey previously told People magazine she did not want a “big wedding.”

Twice-married Carey has a history of being unlucky in love. In 1993, she married music executive Tommy Mottola, which ended in divorce three years later.

She then married Nick Cannon after six weeks of dating and despite a ten-year age gap, but fell out of love with him after seven years of marriage. Carey has four-year-old twins with Cannon called Monroe and Moroccan.

The news comes at the end of a bad week for Carey - who just days ago announced the cancellation of some of her South American tour dates.

On Tuesday, Carey tweeted: “Devastated my shows in Chile, Argentina & Brazil had to be cancelled. My fans deserve better than how some of these promoters treated them (sic).”
