After a whirlwind romance, James Packer is reportedly engaged to Mariah Carey. The news broke on Friday afternoon, with various news outlets referring to a 35-carat diamond ring Mariah has been wearing. The pair first made their debut as a couple in June last year and have since been putting on loved-up PDAs all over the world. They most recently enjoyed some downtime in Australia, when they brought in the new year at James' Crown Casino hotel in Melbourne. Congratulations to James and Mariah!
