Mariah Carey has a brand new piece of jewelry — a massive engagement ring — ’cause her billionaire boyfriend James Packer just popped the question … and Mariah said YESSSSS!!!!
It all went down in NYC — where Packer secretly rounded up a bunch of Mariah’s close friends for a private dinner at Eleven Madison Park … so he could get down on one knee and propose in front of the most special people in her life.
Carey and Packer have only been dating since June 2015 — but their relationship heated up real quick … with the two famously spending several consecutive weeks together on his yacht over the summer.

The relationship blossomed months after Carey split from husband numero dos, Nick Cannon … the father of her two children.
Carey had been married once before Cannon to music mogul Tommy Mottola … so this will be her 3rd marriage.
As for Packer, the 48-year-old has also been married twice before — and has 3 children of his own … so, this is kind of like a celebrity ‘Brady Bunch’ situation … with a lot more money.
Packer is Australia’s 4th richest man — thanks to a combination of family money and success in real estate, casinos and entertainment.
As for the wedding, no word on when it’s set to go down … but at the rate these two are moving, it will probably happen in 2016.
