Happy Halloween! Our favorite stars have been celebrating the spooky holiday all week long by wearing some seriously fun costumes.
Zendaya dressed up as one of her style icons, Aaliyah, and Naya Rivera played detective as Carmen Sandiego. Meanwhile Ariana Grande wore not just one, but three different Halloween outfits and Demi Lovato looked crazy-creepy in her zombie popstar getup. Thank goodness for stars like Lucy Hale, Ed Sheeran and Debby Ryan, who went for funny instead of scary with their costumes!
