She's been captivating audiences with her performance of Lady Macbeth in Macbeth on Broadway, alongside Daniel Craig, and had been nominated for a Tony Award for best performance by a leading actress in a play at this year's ceremony.
However, at last night's awards, it was her dazzling ensemble that captivated onlookers, as the Irish star went for full disco glam on the red carpet.
Negga has cemented her reputation as one to watch when it comes to red carpets and award shows, as the star goes big on drama, glamour and boundary-pushing looks. Whether it's form-fitting gowns, slinky jumpsuits or romantic and feminine dresses, she always stuns on the red carpet.
Styled once again by Karla Welch, Negga wore an inky black custom Armani Privée gown featuring a plunging V-neck in black velvet, a fitted waist, an open back and flowing tiered skirt made of gauzy tulle accented with shimmering crystals.
Adding to the retro femininity of the gown, the halterneck tied in a black bow at the nape of Negga's neck.
She paired this with a shining diamond choker necklace by Tiffany & Co, which popped against the rich black shade of the gown.
For her beauty look, Negga took inspiration from the lush and extravagant style of the 70s, going for a bold red lip, a striking cat-eye eyeliner and lashing of shimmering silver eyeshadow.
Her hair was styled into tight coils that framed her face perfectly.
