The X Factor judge covered her enviable curve with the jaw-dropping slinky silver frock that which revealed a serious amount of flesh that showed that Nicole had gone completely underwear free for the occasion.
With the host of celebrities lit up the party with dresses that showed that they were not wearing any underwear.
The singer turned the uber glam event into a sideboob spectacle, the Pussycat Doll turned to the side, giving a tantalising view of her bustline as she lapped up the camera attention.
Leading down to the hemline, the incredibly revealing panels displayed Nicole's impressive booty, with enough cheek to rival one of JLo's Las Vegas ensembles.
Also in the party spirit was Ellie Goulding, who joined Nicole for an evening of flesh-baring.
The Burn singer stunned on the red carpet earlier in the evening in a particularly boob-baring number and there wasn't any exception for the glitzy after party.
Majorly teasing cleavage, the blonde bombshell partied alongside a star studded guest list including the likes of Katy Perry who opted for a see-through number á la Camila Morrone.
Following on from Nicole and Ellie's lead, Katy hadn't had enough of flashing her killer cleavage and legs to match on the red carpet, opting for something a little more risqué.
