Are you a Katy or a Gaga? Well, that's what the Gleeks will be trying to figure out on this week's episode of "Glee," airing Thursday on Fox.
The episode, titled "A Katy or a Gaga?" will feature four tracks from the respective princesses of pop.
There will be two Lady Gaga tracks, "Marry the Night" (performed by guest star Adam Lambert's Elliot Starchild) and "Applause" (performed by Sam, Blaine, Artie, Ryder and Marley). And there will also be two Katy Perry tracks, "Wide Awake" (Jake, Kitty, Unique, Tina) and "Roar."
It's unclear how the Lima-based New Directions will hook up with New York-based Rachel, Kurt, Santana, Dani (returning guest star Demi Lovato) and Elliot for the track, but they will all perform Perry's empowering Prism single.
Additionally, fans will finally get to meet Lambert's eccentric Starchild character, who wears glittery steam punk-inspired clothes and swings from sparkling chandeliers, much to Kurt's dismay.
"In this episode, Kurt has decided to start a band and he is holding auditions at NYADA. And only one person comes to audition: Adam Lambert. How lucky is he? Well, it's not really Adam Lambert. Adam's playing Elliot. And Kurt gets very, very intimidated because Elliot sings like Adam Lambert," Chris Colfer revealed in a sneak peek of the November 7 episode.
While Kurt is trying to make his rock-and-roll dreams come true in NYC, back at Lima, the New Directions are trying to figure out if they are Gagas or Katys. Castmate Becca Tobin opened up about getting the chance to sing Perry's "Wide Awake," and with a fun twist. "The 'Gagas' sing 'Wide Awake.' This really pretty stripped-down version," she said. "And actually it was my favorite song that I've sung so far."
So, what does Lambert make of the two pop princesses considering he knows both ladies? "I think they're both really talented. And they're both fabulous and over-the-top," he said. "I think they're both at the top of their game."
After the show tackles Katy and Gaga, they will try their hand at Miley's favorite dance: twerking. The November 14 episode of the show is called "The End of Twerking."
