Yay or Nay: Katy Perry's Blue Rinse 'Do

Ah I love me a bit of Katy Perry madness, so I do. The girl can always be relied on for outta this world manicures and perfect winged black eyeliner, and last week she rocked a blue rinse that Marge Simpson would be proud of at the MTV Movie Awards.

Apparently she's been lined up to voice Smurfette in an upcoming Smurf movie, so I guess the wig was a pretty appropriate choice. She should probably hold on to it in case she lands a part as Cookie Monster in a Sesame Street film.

I like it and think she carries it off pretty well - what do you reckon?
