Mariah Carey gushes over her billionaire boyfriend, James Packer

Mariah Carey can't seem to overemphasized how lucky she is to have billionaire James Packer as her boyfriend.

Pagesix reports that the singer couldn’t stop gushing about her Australian beau during an appearance on “The Steve Harvey Show” on Tuesday, all the while flaunting her dazzling diamond pendant from Packer, 48.

“Oh, this old thing,” Carey, 45, joked when pressed by host Harvey about the necklace. “[It was] a very, very big surprise, really nice.”

The couple, who made their red carpet debut at the premiere of “The Intern” in September, have been going strong since April. Though, as Carey shared, they’ve known each other for quite some time.

“We first met in Aspen,” she revealed. “A couple of years ago we were at the ‘Hercules’ premiere. We were talking and laughing and people were getting mad at us and stuff like that. So we hit it off.”

After Harvey, 58,  playfully deadpanned, “Ain’t he lucky,” a glowing Carey nodded in agreement.

“I’m lucky too.”
