The 'Boomerang' singer joined a star-studded guest list - which included Victoria Beckham and Eva Longoria - at the 5th annual Global Gift Gala, held at the Four Seasons Hotel.
Former Pussycat Doll Nicole kept things chic and sophisticated for the occasion, highlighting her silhouette in a figure-hugging dress from the Ermanno Scervino spring/summer '15 collection.
Her pretty frock featured a nude floral mesh design which was dotted with silver studs which shimmered as she struck a pose for the cameras.
She added even more bling to her getup by slipping her pins into a pair of strappy heels covered in dazzling gold glitter - we love!
The starlet accessorised her look with a few dainty bangles and silver rings, adding huge gold hoop earrings while showcasing a polished pale pink manicure and deep purple pedi.
But it's not just her outfit we're loving - Nicole totally hit the mark on the beauty front too, wearing her brunette locks in a side parting while slicking the lengths behind her shoulders.
To finish her look, the former X Factor judge lined her peepers with jet black kohl pencil while adding a sheen with shimmery lilac eyeshadow, painting her pout with a deep crimson hue for a touch of old Hollywood glam.
Her outing comes the day after Nicole made her musical comeback on Sunday's X Factor (16 November), taking to the stage to perform her new single, 'Run'.
However, the star later revealed she was "gutted" following her performance, saying there should have been bright strobe lights and lasers, however a technical malfunction prevented these from working. Oops!
