And it seems The Saturdays' Vanessa White may have noted it too as she's since stepped out working a similar look!
Vanessa attended the We're the Millers film premiere last night (14 August) looking oh-so-chic in a black leather pencil skirt and printed chiffon shirt.
Her outfit earned her serious style points but eagle-eyed beauty mavens will have noticed her nails were pretty stunning too.
While Vanessa's nail shape was slightly shorter and totally more wearable, she worked white polish just like Beyoncé.
Want to nail the look? Choose Barry M Matte White, £2.99, Seche Porcelain II, £9.95, or Kim Kardashian's favourite, Orly White Out, £10.25, for a suitably blanked-out shade then follow our step-by-step guide to pulling white nail polish off.
Jessie J and Vanessa Hudgens love the look too!
