Back in January, Katy Perry promised MTV News that her Grammy night performance would include fruit. At first, it seemed like she may have been fooling around, but Perry turns out to be a woman of her word.

"I'm going to be ascending from the ceiling," she told MTV News Saturday night at the Clive Davis Pre-Grammy Gala. "By banana!"

But that isn't the only trick that the Grammy nominee has up her sleeve for her performance of "I Kissed a Girl." She also plans on including some retro choreography in her routine. "It's a little 1940s Folies Bergère/ Rockette [style]," she explained. "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."

On this rainy weekend in Los Angeles, Perry has been busy getting ready for the show instead of hitting the party circuit. "I've been getting my rest and doing rehearsal," she said. "I'm nervous! I have this little sick-to-my-stomach feeling. I think it's a healthy feeling."

On a night chock-full of superstar collaborations, Perry won't exactly be on her own. She's the featured artist for the "My Grammy Moment" contest, which will broadcast the winning videos of fans singing her song while she's onstage.

"If I was a 12-year-old kid and pushed record and had my video appear on the Grammys as I'm sitting there eating popcorn, I would have fainted," she said. "[I would have been] blown away!"

Will Lil Wayne grab all the gramophones? Is Katy Perry going to tell her girl rivals to kiss off? Can Coldplay march off with a win? MTV News is all over the 51st Annual Grammy Awards, so stay tuned for interviews, analysis and more before, during and after the big night, Sunday, February 8.
