Hello, wardrobe envy!
Fleur looked incredibly chic in the head-to-toe white ensemble which boasted a pair of silky trousers with a KILLER flare and a longline wrap-over jacket that drew attention to her fabulous figure.
Never one to blend into the crowd, Fleur jazzed up her look with a pair of hot pink pointed court heels, giving fellow guests Rita Ora and even Princess Beatrice (yeah, we went there!) a run for their money in the style stakes.
When it came to her corkscrew curls, the Sax songstress ditched the eye-popping fiery red she rocked to this year's BRIT Awards (it was cer-azy amazing) for a much more natural, honey hue.
She didn't ditch the colour completely though, and dressed her plump pout in a scarlet lippie that complemented her absolutely stunning mauve eye make-up look.
