Glee sure do love Katy Perry - they're set to do Teenage Dream in the next few weeks, but this video shows they'll be doing California Gurls in the near future:

 

 

I'm not sure if it'll be sung - but it looks like Cheerios will at least be dancing to it, with BLUE HAIR! :lol:

Santana looks so good with blue hair :wub:

 

Also rumour has it that in a future episode

'Firework' will also be used!

(Although that's all it is at the moment, a rumour! :lol:) I think that song will suit the "Glee-ified" choir, sound. They made 'Teenage Dream' work so well!

 

FIREWORK!
