Stars took their celebrations to London at Jonathan Ross's Halloween party last night. The British TV and radio host threw a bash that was attended by Helena Bonham Carter, Tim Burton, and Mark Ronson, among others. Kate Moss had her face painted as she arrived with husband Jamie Hince while Gwen Stefani was a bloody version of Sandy from Grease. Gwen had No Doubt bandmate Tony Kanal by her side after taking Zuma trick-or-treating earlier in the evening. Chloë Moretz was also on hand in a spooky pirate costume. There were plenty more celebrity costumes last night and over the weekend, when the celebrations got started, so make sure to see them all!
