By now the whole world knows that Katy Perry's flying solo, but now she's looking to her fans for company! As part of this year's "My Grammy Moment," Katy will perform with contest-winning videos of her fans singing "I Kissed A Girl." She's nominated for best female pop vocals, so Katy lovers better practice if they want a shot at singing backup. To enter, fans need to upload 30-60 second clips of themselves before midnight on February 6 at www.cbs.com/grammys. The winning vids will be voted on by the public and will air as part of Katy's Grammy!

"I am very excited to be a first-time Grammy nominee and new Recording Academy member this year, and even more thrilled to perform on music's biggest stage in February," Katy says, according to People. "I'd love to share my first Grammy experience with all my fans, so I encourage you to submit your videos now!" Good luck, girls!
