Mariah Carey and James Packer couldn’t look happier.

The pair stepped out at the G’Day USA Gala in Los Angeles on Thursday and shared laughs and intimate whispers.

Carey donned a black, sparkly, long-sleeve dress alongside her billionaire beau who sported a black tuxedo.

The two beamed as they sipped drinks at their table, with Packer often gazing at his wife-to-be.

The only thing emitting more sparkles than Carey’s dress? Her massive engagement ring (35-carat engagement ring, to be exact).

She flashed the jewelry multiple times with hair flips and waves.

Packer and Carey were among celebrities like Hugh Jackman, Seal, Nicole Richie and Joel Madden to attend the networking event.

The outing marks Packer and Carey’s first public appearance as an engaged couple.

The proposal took place in Carey’s hometown of New York City on Jan. 21 and a source previously told PEOPLE that the singer (and lover of all things lavish) is living a fairy tale.

“Mariah was always a hopeless romantic. She deserves the dream and I am sure James will give her just that,” the source said.

“[She has] always loved being showered with roses and diamonds and now her princess fairy tale is coming true.”
