An array of impressive Halloween costumes lit up the celebrity circuit this year, as stars turned out for parties and charity events.
Model Heidi Klum's old lady attire was eerily accurate for her annual Halloween bash in New York, while in the UK former supermodel Jodie Kidd donned a cloak and mask for a Dracula-inspired look at the UNICEF Halloween Ball at One Mayfair in London.
Four Weddings and a Funeral star Hugh Grant was happy to wear an an ornate cat mask to the UNICEF Ball, though the rest of his outfit wasn't quite in the spirit of Halloween...
The ball was hosted by Ewan McGregor to raise funds to provide essential supplies for children suffering in war-torn Syria.
In New York, actress Liv Tyler sported a fake scar, scary white pallor and dishevelled hair to take her son Milo trick-or-treating in New York, while TV presenter Matt Lauer went for a less spooky Baywatch theme - dressing as Pamela Anderson for the 'Today' show.
The biggest hair of the evening came courtesy of Iggy Azalea, who channelled Lily Munster in her performance at the Vevo Halloween Party in London.
