Even though Halloween hasn't taken place yet, the infamous Halloween celeb parties have started and the stars were out in force showing us how they do Halloween dress up!
Take a look at the best of the bunch so far and maybe take away some inspiration for your costume....
Paris Hilton isn't one to care about what she is seen out in even on a daily basis, so her Halloween costume was always going to be, let's say 'out there'. Showing quite a bit of skin she has decided to go for a Miley Cyrus look from her controversial 'We Can't Stop' music video.
We actually really like this more demure look from Nicole Richie. Sporting only black lace cat ear's, this isn't really a full on Halloween look, but we don't care because we just love this dress!
Looking positively terrifying, Sandra Bullock donned a full on traditional style Halloween costume while out with son Louis and even had the makeup to go with it. We won't be wanting our makeup done by her makeup artist anytime soon.
Victoria's Secret angel Alessandra Ambrosio obviously could never look bad in her Halloween costume, this year dressing up as 'The Queen of Hearts'.
Derek Hough looked barely recognisable in his 'Adam Lambert' costume. 10/10 for effort but what was he thinking and that hair!
