All manner of great, good and evil from the celeb world got fully involved in the Halloween festivities this year.
Anyone who was anyone made their way to Jonathan Ross's North London house for a sinister and spooky bash.
Holly Willoughby peeled off her face, Louis Theroux performed surgery and Jack Whitehall came as the bass player from the Red Hot Chilli Peppers.
Further afield, Dita Von Teese and a blood-curdling array of celebs attended the New York Restoration Project's 17th Annual Hulaween Ball at the Waldorf Astoria in New York City.
In Nottingham, Ed Sheeran performed as a ginger person.
I'm ginger so I'm allowed to say that...
