There were a ton of celebrity Halloween costumes, most of which turned average-looking whores into average-looking whores in brightly colored cleavage-enhancing outfits. It's really the best holiday ever. That being said, I'm going to focus on the good and the bad - literally:

Mariah Carey, and husband no-one-cares-about Nick Cannon, went as angels for Halloween. I'm not sure who gave her permission for that one. Even if God himself parted the clouds and gave her the OK, I'm still thinking, "Yeah, did you see Glitter, God? No? You knew to stay away from that piece of garbage? Ah, now I see why you're all-knowing." I like the boobs though, Mariah - nothing says heavenly creature like boobs. Seriously.

On the other hand, AnnaLynne McCord went as some sort of evil Batgirl knock-off, making it OK for me to create my own superhero: The AnnaLynne-McCord-Fiend. You don't even want to know what my power is (...it's masturbating to AnnaLynne McCord. Don't try to steal it, it's copyrighted).
