1106-mariah-carey-james-packer-tmz-getty-01Mariah Carey is now living with James Packer, TMZ has learned, 5 months after they started dating.

TMZ has learned ... following her big Halloween soiree, Mariah's staff packed up her stuff and moved it to Packer's Beverly Hills home. She probably got a good deal with the movers ... Packer's house is only 5 minutes from the house she's been renting.

It's a big move for Mariah and the Australian billionaire ... we're told they've openly discussed the end game ... marriage.

BTW ... Mariah took a lot more than clothes. Bedding, furniture, the works. Looks like James' mansion is about to get some new flair.
