Mariah Carey and James Packer

Mariah Carey and James Packer might not be heading to the altar after all. News broke today that the songstress and her billionaire fiancé have split after nine months of engagement.

Packer proposed to Carey in January with a 35-carat diamond ring. “It’s so heavy, I can’t lift my arm up,” Carey told E! shortly after the engagement. The proposal took place in New York, where Carey is from. Packer is from Sydney, Australia.

It’s unclear what exactly caused the pair to break up. TMZ is reporting that Carey’s upcoming E! documentary series — not to be mistaken for a reality show — was a source of contention between the two. The site is also saying that a supposed “rendezvous” between Carey and one of the dancers from her Vegas show could be at the root of the split. There’s additional speculation that Carey’s “extravagant spending” is to blame. Though none of these reasons for Carey and Packer’s split have been confirmed by the couple, the latter seems doubtful. It’s Mariah Carey, queen of extravagance, after all. The woman wore heels while pushing her son Moroccan around Disneyland in a stroller.

Carey’s upcoming E! show, aptly titled “Mariah’s World,” is set for a Dec. 4 premiere. The eight-part series is said to document Carey’s Sweet Sweet Fantasy Tour in the U.S., Europe and Africa. It will also supposedly clear up any misconceptions about Carey. What misconceptions exactly? We can’t be sure.

In a trailer for the show, Carey can be seen lounging on a chaise. “Is this a normal outfit for people to wear?” she says while wearing a bodysuit, fishnets and jewelry. “I don’t know. But I’m at home and this is what I wear.”

Here’s hoping Carey and Packer sort things out for the best.
