Not to be outdone by the self proclaimed Female Boss, who turned up to the party as a sexy vampire, Nicole made everyone's eyes pop in a PVC bask, complete with rubber gloves and fishnet stockings. Oooh, what would Louis Walsh say?
We're calling the look 'the artist formally known as the one from the Pussycat Dolls revisits her past, and then some'. Catchy, right?
The pair (we're talking about Tulisa and Nicole) have been quick to deny any rumours of a feud between them and were happy to pose together at the bash at Mahiki nightclub in London.
Most recently, Nicole said she was jealous of the N-Dubz star's 'great puppies' during an interview on 'The Xtra Factor', but by the look of these snaps, we don't think she's got anything to worry about in that department.
