'Glee': 'A Katy Or A Gaga' Pictures Are Awesome


"Glee" is asking a very important question: Are you "A Katy Or A Gaga"?

The battle of the pop divas has continued this entire fall on the music charts. Between Miley, Katy Perry, and Lady Gaga all trying to beat one another for the top spot, it seems that music lovers had to pick a camp to belong to, and now the battle of the pop princess has taken McKinley High as "Glee" takes on the music of Katy Perry and Lady Gaga.

The "Glee" cast battles it out in the next all-new episode which features the cast singing various Katy Perry and Lady Gaga songs, and there's even a guest performance by Adam Lambert, who will sing Lady Gaga's "Applause."

Check out the trailer for the episode below and to see photos from the episode "A Katy or a Gaga" check out the slideshow.
