Star Spotting: Katy Perry's All 'Purple Is The New Blue'

Looks like Katy Perry's now-signature blue wig from her "California Gurls" cover art and 2010 MTV Movie Awards performance isn't her signature wig anymore. Yesterday she performed "California Gurls" on "Germany's Next Top Model," which is clearly a more musical affair than "America's Next Top Model" (though that episode where Tyra Banks shot her "Shake Ya Body" video and all of the girls were in was a classic). Gone was the Smurfette-blue wig, which Katy replaced with a great grape-y purple wig instead. It's totally over the top in a summer-fun sort of way. And if anyone can make purple hair look good, it's Katy Perry. After all, she wore a Swiss cheese-inspired dress and still looked hot.

+ Watch Katy Perry and blue wig (and Snoop!) in action at the 2010 MTV Movie Awards. And don't miss the premiere of Katy Perry's "California Gurls" video on Tuesday, June 16 on MTV.
