Mariah Carey and billionaire James Packer have split over the pop star's "extravagant spending", according to reports.

Rumours of the pair's relationship being on shaky ground have been building since their much-hyped wedding was delayed in March - now, it appears, they've called it quits.

"It's all over," a source told Woman's Day.

"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 the women's magazine, Carey "created tension" within the Packer family by refusing to attend her fiancé's 50th birthday and "struggled to connect" with matriarch Ros Packer.

James Packer's private jet arrived in Melbourne overnight while Carey has also cancelled a series of South American performances.

The reports are yet to be confirmed by reps of either Carey or Packer.
