Rita, 30, sparkled in a silver embellished floor-length skirt and matching strappy top, which revealed a hint of midriff, as well as heels and a handbag in the same material to complete the look.
Her black satin wrap tied in perfectly with her 46-year-old beau’s double-breasted tux jacket and trousers, which he wore with patent shoes, a crisp white shirt and black tie.
Taika also returned the favour to his How We Do singer girlfriend by adding subtle silver and sparkle to his outfit with a long-chained silver pendant.
The Voice Australia judge Rita was dripping in diamonds, including around her neck, on both wrists and hanging from her lobes.

The star had also packed blinged up her manicure and decked out plenty of her fingers in diamond bands.
The couple posed in black face masks, before larking around for photographers, with Rita giving Taika a peck on the cheek and the Thor: Love and Thunder director pulling a wide-eyed expression.
Rita also stuck her tongue out at photographers on the steps, and the pair mucked around with US TV host Jimmy Fallon.

The couple is used to rubbing shoulders with the stars, having celebrated Taika’s 46th birthday together in August with the likes of Kate Beckinsale, Kristen Stewart, Charli XCX, Jodie Turner-Smith and Ashley Benson, alongside a mariachi band and decorations adorned with Taika’s face.
