NICOLE SCHERZINGER got hellishly hot ahead of Halloween next week (31Oct12) by donning a latex basque for a spooky night out in London.

The singer is in the U.K. for her role as a judge on The X Factor, and showed support for one of her acts by turning up in costume to contestant Rylan Clark's All Hallows Eve-themed birthday bash on Wednesday (24Oct12).

Scherzinger stunned revellers at the party at Mahiki nightclub by bursting out of a giant cake in a saucy red and black corset, leather gloves and fishnet tights to sing Happy Birthday to the 24 year old.

She posed for photos with her fellow judge, British pop star Tulisa Contostavlos, who was dressed as a vampire French maid and pretended to bite the ex-Pussycat Dolls beauty's neck.
