Are you loving Katy Perry's hipster eyewear, or should she have left her face bare?

Does Nicki Minaj's latest outrageous get-up give you a good feeling, or is it crazy-revealing?

Are you totally jealous of Jennifer Aniston's bikini body, or is her choice of swimwear looking a bit shoddy?

Is Michelle Obama's black-and-white dress simple and chic, or do you find this look kind of weak?
