It's that time again! Some of the biggest names in Hollywood stepped out to celebrate Halloween 2013, dressed as film characters, other A-listers, comic superheroes and much more! Check out some stars -- including Hilary Duff, Vanessa Hudgens and John Stamos -- who went the extra mile to get decked out for some of the biggest Halloween parties of the season.
Imitation is the sincerest form of flattery! Miley Cyrus channeled yet another famous singer as she dressed as Lil' Kim, circa the 1999 MTV Video Music Awards. The "We Can't Stop" singer shared a selfie of the purple (and very revealing!) outfit with her fans via Twitter shortly after midnight.
