In recent months Kelly O has spanned the fashion lexicon: grunge, ladylike chic, vamp and rocker – it was only a matter of time before cabaret artist got into the mix.

The newly svelte star flaunted her fabulous figure in a racy routine with the Pussycat Dolls in front of a star-studded audience at the Viper Room in LA. Sporting a skimpy silver sequinned dress, fishnet tights and a red military cap she looked every inch the burlesque beauty.

Kelly was joined by Carmen Electra and singer, Mya, for the sizzling performance. Among the celebrity fans was Kim Kardashian who posted her enthusiastic response on Twitter: 'OMG @KellyO just killed it!!.

We're pleased to see Kelly looking happier than ever after her difficult split with fiancé, Luke Warrall, earlier in the summer.
