Mariah Carey was all smiles and glamour as she partied at 1Oak Nightclub at the Mirage Hotel & Casino in Las Vegas.

The 46-year-old artist — who is now dating a billionaire by the name of James Packer — hit up the popular club over the weekend, after performing her show Caesar’s Palace, #1 to Infinity.

Mariah rocked a form-fitting, long black gown but all eyes were on her new, yellow heart shaped diamond necklace. Reportedly, the necklace was an extremely pricey gift — worth $500K — from James.
