Kelly Osbourne flaunted her newly-fit frame in a racy song and dance performance on Wednesday night, taking the stage for a strip show with Robin Antin's burlesque troupe The Pussycat Dolls.

The reality TV star has slimmed down to a tiny size two since her stint on TV competition Dancing with the Stars - and celebrity choreographer Antin took notice of her newfound confidence.

Antin took to Twitter.com to post a sexy picture of the reality star as she arrived in a silver sequined micro mini dress ahead of the show at the Viper Room in Los Angeles on Wednesday - where she joined PCD Revue regular guest Carmen Electra for a sexy strip.

And her raunchy show looks like it may be headed to the big screen for the world to see - recent reports suggest the event was filmed for Donovan Leitch's new documentary Sunset Strip.
