Of course, seeing Carey continue to wear the pricey bling doesn't come as a complete surprise. Shortly after the 46-year-old singer and the Australian billionaire called it quits in October, a source told ET that Carey "is keeping the ring."
What's more, a source close to Carey told ET, "She's ready to move on."
And it seems the GRAMMY winner has done just that. Hot on the heels of their steamy Hawaiian beach rendezvous, Carey and her backup dancer, Bryan Tanaka, were seen looking cozy at a screening of Carey's new E! docuseries, Mariah's World, earlier this month.
"Mariah's chemistry with Bryan was subtle, but undeniable," an onlooker told ET. "It is the way they communicate. They seem so happy in each other's presence. They are on the same page -- their laughing and the glances between them."
The couple made headlines recently after being snapped locking lips and frolicking in the waves during their recent Hawaiian vacation.
