Mariah Carey accompanied her boyfriend James Packer to the grand opening of his $3.2 billion casino resort, Studio City, for a date night in Macau, China, Tuesday.

Carey and Packer walked the red carpet for the launch of the Hollywood-themed resort hand-in-hand. The couple matched in black, as Carey donned a plunging black gown alongside her tuxedo-clad boyfriend.

Carey even lent her vocal chops to the evening, singing her hit song “Hero” to commemorate the resort’s opening.

There to celebrate the opening alongside Carey and her billionaire Australian beau were Leonardo DiCaprio, Martin Scorsese and Robert De Niro, who premiered the 15-minute short film The Audition. In the short, there’s a faux battle to star in Scorsese’s next Oscar-baiting picture. Brad Pitt also appears in the short, which was penned by The Wolf of Wall Street screenwriter Terrence Winter.

The Audition was produced by Packer and Brett Ratner’s RatPac Entertainment. They reportedly paid $70 million for the short as a way to publicize the Studio City resort.

Prior to Studio City’s launch, Packer and Carey made their red carpet debut at the premiere of De Niro’s latest feature film, The Intern, back in September.
