Mariah Carey was showing off her enormous engagement ring from James Packer to Beyoncé at the Heartview Global Foundation gala in LA Thursday night.

Both singers were there to support their mutual business manager, Jonathan Schwartz, who was honored at the event to raise money for heart-disease research.

“Bey congratulated her on her engagement and Carey was flashing the ring to everyone,” said a spy.

Carey posted an Instagram shot of the two and wrote, “Two girls, one cause.”
