Back in September there were rumors that Mariah Carey’s billion dollar boyfriend James Packer was planning an elaborate proposal.

So did James go ahead and pull the trigger?

Sure looks like it.

Mariah Carey is scheduled to perform at James Packer’s Crown Casino and Entertainment Complex in Melbourne, Australia on New Year’s Eve and according to reports MiMi was spotted on the casino floor yesterday flashing a big diamond ring on THAT finger.
