The X Factor judge let her hair down while partying up a storm at The Arts Club in Mayfair, London, straight after filming The Jonathan Ross Show.
Stunning Nicole oozed sex appeal in her daring frock, which featured a racy plunging neckline and a cut-out detail across her midriff.
She drew even more attention to her curvaceous assets by wearing several delicate gold necklaces.
Lime green courts added instant zing to her look, and she styled her sunkissed brunette locks in loose tumbling curls.
It seems Nicole had a whale of a time on her evening out, Instagramming pictures with her girl friends while posing in the club's restroom.
Clearly eager to show off her lengthy pins, the 'Boomerang' singer lounged on a velvet chair while kicking one leg in the air.
She then smiled alongside a pal in yet another smouldering snap, adding the caption: "#bathroombreak photoshoot."
If this doesn't show ex-beau Lewis Hamilton what he's missing, we're not sure what will!
