Katy Perry took the stage off the rocker at the 2009 Grammy Awards held at the Staples Center in Los Angeles on Sunday (February 8). Geared in rather exaggerated attire, the 24-year-oldperformed her smash hit number “I Kissed a Girl”; twisting and twirling all along for the audience!

Katy confides about the performance previous to the show; to a reporter, “I’m going to be ascending from the ceiling… By banana!”  The choreography had a slight retro fling!

“It’s a little 1940s Folies Bergère/ Rockette [style]. It’s definitely not [like Britney Spears' 2001 VMA performance of] ‘I’m a Slave 4 U’ or something like that. No anacondas on my neck. It’s definitely hopefully going to be one of those moments” adds the hottie.
