It looks like Mariah Carey will be tying the knot yet again. The singer, who split with Nick Cannon in 2014, has just announced her engagement to Australia's fourth-richest person, billionaire James Packer, after about 10 months of dating, per the BBC. Her rep tells Us Weekly that Packer, 48, graced Carey, 45, with a 35-carat rock on Thursday night in New York City, shortly after the pair returned from a romp on Packer's yacht in St. Barts. If all goes as planned, the wedding will be the third for both Carey and Packer, who runs a number of casinos, reports E!. (Click to see how Cannon feels about his ex's relationship.)
