'Glee' channels Katy Perry and Lady Gaga for 'A Katy or a Gaga'

glee-a-katy-or-a-gaga-fox-1-artie.jpgIt's not just about the music when "Glee" returns with "A Katy or a Gaga." The kids will channel Katy Perry and/or Lady Gaga as they try to find themselves. Crazy costumes and elaborate set pieces will of course be a part of this.

Photos from the episode are kind of incredible, even if it's not always obvious if Katy or Gaga is the theme.

For Sam's ( Chord Overstreet) photo, he is almost definitely going the Gaga route.

Also going Gaga is Artie ( Kevin McHale).
