Halloween is amazing for so many reasons. Beyond the candy and parties, it's the best time to see our favorite celebrities in a different, more creative, light. Hollywood's biggest stars step out for their gowns and suits and into elaborate costumes that leave us in awe. Remeber when Ciara and Russell Wilson transformed into Catwoman and Batman? And we loved when Rihanna and her friends were the Teenage Mutan Ninja Turtles. Or how about the epicness of the Carters (aka Jay Z, Beyoncé and Blue Ivy) recreating the royal family from Coming To America. Genius! Take a look at those amazing moments and more as we rundown the best celebrity Halloween costumes of all time.
