Halloween is a time to dress up, be fabulous and channel all of your energy into becoming a new character ... so there is little surprise that Hollywood's rich and famous take to the celebration like ducks to water. Whether they are embodying their favourite fictional characters, as Liz Hurley and Khloe Kardashian have both done in the past as <em>Kill Bill</em>'s The Bride and Cruella de Vil, or they are channelling a fellow starlet, as per Rita Ora and Ciara, who dressed as Post Malone and Beyonce, the A-list takes Halloween very seriously. Sure, they may have a little more cash to throw at their costume commitment – we're looking at you Heidi Klum, who is said to have spent as much as $10.5 million on Halloween costumes in the past – you may find a little inspiration for your costume this year in our celebrity gallery. <strong>Click through the gallery above to see the best celebrity Halloween costumes from years gone by. </strong>
