There is no better excuse than Halloween to crack open the fancy dress box, and celebrities on both sides of the pond pulled out all the stops for this year’s celebrations.
Over in LA, Heidi Klum hosted her annual spook-tacular, where Mel B was in attendance to make a massive dig at her former Spice Girls bandmate Victoria Beckham.
The host herself stole the show - as usual - with her efforts, this year enlisting her boyfriend Tom Kaulitz to go as the Shrek to her Princess Fiona.
Back here in Blighty, Jonathan Ross held his annual shindig at his London home, with the likes of Keith Lemon, David Walliams, Craig Revel Horwood and Shirley Ballas all dressing up.
There were also impressive outfits from the likes of Rihanna, Harry Styles and Amanda Holden who were also out celebrating Halloween.
