Jonathan Ross's annual Halloween party has quickly established itself as one of the biggest showbiz bashes of the year and he pulled out all the stops again this year with a guestlist that read like a who's-who of celebland (once you'd worked out who was behind the make-up, at least).
Kate Moss
Among the guests to don their scariest slash weirdest costumes - a sheet over the head won't cut it - were Kate Moss who came dressed as a gothic ghost (or Helena Bonham Carter - we're still trying to work that one out), Holly Willoughby who was some sort of weird butterfly woman (which was a LOT less scary than last year's costume) and Nicole Scherzinger who vamped it up as catwoman.

At first we thought host Jonathan had come as some 80s soft rocker but it turns out he was actually the Goblin King from 1986 film 'Labyrinth'.
It had taken a group of artists more than 24 hours to transform the chat show host's north London home into a gothic castle - complete with Simon Cowell pumpkins on the doorstep.
Nicole Scherzinger
Other guests included Millie Mackintosh and hubby Professor Green, Claudia Winkleman, Simon Pegg, Lily Allen, Jack Whitehall.
But the award for best costume of the night has to go to Lily Allen who looked out of this world as a little green (wo)man.

Well done everyone.
