Halloween just wouldn't be the same without taking a quick look at what some of our favourite stars wore. Hollywood's infamous Halloween party thrown by Heidi Klum had all of Tinseltown out in their most ghoulish garb. The hostess herself (just two weeks after giving birth to her fourth rugrat) was barely recognisable as a giant black crow, Klum took inspiration for her costume from her daughter Leni's favourite film, Howl's Moving Castle. But my favourite has to be Perez Hilton's outrageous Lady Gaga get-up, check it out after the jump...

While back in London, it was the annual Browns Focus Halloween party that attracted our favourite fashionistas in their scary best. Dressed as Johnny Depp in Edward Scissorhands, Henry Holland denied rumours that he'll soon be joining the next series of I'm A Celebrity ... Get Me Out Of Here or Big Brother. He partied with Pixie Geldof who chose the occasion to get a little bit goth - how very on trend!
