Katy Perry, Lady Gaga to perform at Grammys

A partial list of the evening's performers has been released and some of music's brightest stars will be lighting up the stage on February 13, including Katy Perry and Lady Gaga!

Lady Gaga takes on the O2 Arena as she continues her "Monster Ball" world tour.

Singer Katy Perry aka Katy Brand accepts the Favorite Female Artist and Favorite Pop Artist awards onstage during the 2011 People's Choice Awards at Nokia Theatre L.A. Live on January 5, 2011 in Los Angeles, California.

The Grammy Awards are exactly a month away, and the hype has already set in, and for good reason. A partial list of the evening's performers has been released and some of music's brightest stars will be lighting up the stage on February 13, including Katy Perry and Lady Gaga!

The initial list of performers for the big night also includes Miranda Lambert, Eminem, Arcade Fire, and Cee Lo Green. It's definitely going to be an exciting show!

Eminem will take the stage (with Rihanna, perhaps?) and could very well make several trips back to the mic throughout the evening if he wins any, or all, of his 10 possible awards.

For that matter, all of the performers could be called to the stage over the course of the evening: Gaga is up for 6 awards, Green and Perry have 5 nods, while Arcade Fire and Lambert each have 3 nominations.
