Look Back at Last Year's Best Celebrity Halloween Costumes!
Halloween is coming! You only have a month to perfect your costume, so it really is time to start thinking about it. Luckily, we have last year's amazing celebrity Halloween costumes to inspire use. Not only did we see new costumes at Heidi Klum's star-studded bash, Maroon 5's big event, and Adam Lambert's party, but stars also showed off their spooky and sexy looks on Instagram. Jonathan Ross's pals pulled out their scariest garb, Gerard Butler took on the role of a knight, and Katy Perry got cheesy in a Flamin' Hot Cheeto getup. That's just the beginning of the fun — scroll through to see stars dressed as everything from rock stars to superheroes.
