Mariah Carey’s billionaire's boyfriend James Packer put $500,000 worth of rocks on her chest on Thursday before her performance. Packer gave Mariah an 18 karat yellow heart-shaped diamond, which he gave to her right before she went on stage for her Vegas show at Caesars Palace. She gave a shout out to him after her performance.
Mariah Carey thanked JP for "a new heart" ... right before she sang "Hero" that night.
She told the audience: 'I have a new heart tonight' as the crowd whooped and cheered.
Mariah continued: 'James is in my heart tonight.'
Before she went on stage Mariah took a shot of herself in her new jewels and posted it on Thursday morning.
She captioned it: 'Happy backstage right before last night’s show...#NTT “‘If you look inside your heart.'
