Lady Gaga tops Halloween-costume list

Lady Gaga is known for her show-stopping outfits and a tendency to don a meat dress rather than red-carpet ruffles. This Halloween, she'll lose a little of her originality when people across the world create Gaga-esque homemade eggshell cases and teacup accessories.

Lady Gaga topped the 2011 ShopRunner list of celebrity Halloween costumes, followed by Kate Middleton (fascinators will suddenly have a U.S. market). Katy Perry took third on the list, no doubt thanks to her array of wild costumes and rainbow hair.

Charlie Sheen ranks fourth (T-shirts are undoubtedly being tagged with the word "Winning!" at this very moment). And Kim Kardashian rounds out the list, which requires a hefty faux ring to look authentic.
