"You know what? I would take 'Party in the U.S.A.' in a second," she told MTV News. "I would take it in a heartbeat. I love that song."
The "American Idol" champ said she'll be singing a hit or two of her own for the show and would love the chance to collaborate onstage with one of the newbie divas or even an established diva, including her three favorite: Mariah Carey, Celine Dion and Christina Aguilera.
"I think it would be really cool if we all could sing a song together. I know the moment I try and out-sing somebody else, I will sound horrible," she joked. "I was hoping that I could sing with somebody as well. I named a few people like Mariah [Carey] and Whitney [Houston], but that's probably not going to happen.
"I'm so stoked," she continued. "I remember hearing about the Divas shows and watching them when I could, but I usually had to go to sleep when I was in school so I couldn't usually watch them. ... I'm so excited. It's going to be so much fun."
The night will also reunite the singer with former "American Idol" judge Paula Abdul, who will be the night's host. Sparks is definitely looking forward to sharing the stage with Abdul again. "I'm so excited to see her. I can't wait to give her a huge hug," she said. "I love Paula."
