'X Factor': Nicole Scherzinger Upstages Tulisa In Sexy PVC Bask At Rylan Clark's Halloween Birthday (PICS)

As a former member of the Pussycat Dolls, Nicole Scherzinger is no stranger to a spot of raunch, but she took it to a whole new level at Rylan Clark's birthday party last night.

The 'X Factor' judge turned up to the bash to celebrate with her protégé, but the on-going fashion war with fellow judge Tulisa continued, despite the Halloween theme of the evening.

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.
