And how COOL is her latest hairstyle? Top marks, Nic!
The Don't Hold Your Breath songstress is famous for her ultra-glamorous sense of style but she toughened things up in this skin-tight mini dress that boasted a sassy circle choker, a matching waist belt and co-ordinating chest detail that drew attention to the fact that she had totally ditched her bra.
Hello there, cleavage.
Thankfully, Nicole managed to avoid an embarrassing wardrobe malfunction (as did ex TOWIE star Ferne McCann during the evening - you have to see her top!) and she slipped into a pair of failsafe strappy sandals with a killer heel - those legs, though.
It was Nicole's hair that completely stole the show, however, as she channelled her inner Spice Girl and rocked 90s-inspired space buns - we're absolutely loving the Halloween-esque purple, too! Our look = totally sorted.
When it came to her make-up (flawless, as always), Nicole made like Love Island's Cara de la Hoyde, also out on the town, and sported an ultra-girly pink lip to offset her magenta-toned buns and a seamless feline flick.
After grabbing a bite to eat, stunning Nicole joined both Pixie Lott and will.i.am at the MCCVIII Luxury Sneaker launch at London's Harrods.
A star studded night all round!
