Mariah Carey ‘wants millions’ from James Packer

Mariah Carey is keeping her $10 million ring from her billionaire ex-fiancé James Packer — and now she “wants millions in a settlement” for uprooting her life to be with him.

Carey was spotted out at Nobu in Malibu, Calif., on Thursday night in an eye-catching, skin-baring outfit and still flashing her titanic 35-carat diamond ring from Packer.

The couple split following a fight on his yacht in Greece in September amid rumors that the diva had been hooking up with backup dancer Bryan Tanaka.

According to reports, Carey is now seeking $50 million from Packer for uprooting her life to move to LA for him, and claims she’s so traumatized by the split that she’s had to cancel the South American leg of her tour.

But a source close to the warring ex-couple said, “Of course Mariah wants money, but she’s not getting $50 million. There’s no negotiations about money because they haven’t spoken since the split. He let her keep the ring, and she isn’t getting a cent more. It is ridiculous to claim that James is the reason for the cancellation of her South America tour. A few days ago she blamed it on the promoters.”

Carey’s friends have hit back with claims that he became crazed over her “close relationship” with Tanaka, who was at Carey’s Halloween party last weekend and also with her at Nobu.

A source told us, “She was screwing around with Bryan. James found out about it, and it was one of the reasons they split.”

Tanaka was one of the dancers who carried the singer out on a chaise lounge during her performances.

Packer strongly denies allegations of an incident on his yacht in Greece that led to their split. His rep has said of the claims, “This is simply untrue.”

Meanwhile, reps for Carey say the split was not due to cheating, saying, “Mariah and James had a fight in Greece, and have not seen each other since. The fight was not because of any cheating allegations or excessive spending by Mariah.”

Their spokespeople didn’t comment further last night.
