While Katy Perry toned it down, stars like Nicki Minaj opted for offbeat
Best: Nicki Minaj
Yes, she showed up with a fake Pope in a Versace nun/Little Red Riding Hood outfit, but isn't that part of the fun? Big props to Minaj for pushing the envelope, inviting controversy and doing it in couture. I think it's a pretty safe bet there's something much more interesting under the cape as well.
