"I can tell you you'll see my performance [on the show] on Wednesday night, I'm so excited!" Abdul told Idol host Ryan Seacrest during a Tuesday morning appearance on his KIIS-FM radio show, which also featured the song's world premiere.
"It's official... it's going to be pretty exciting," Abdul added about the performance, which will be the first time the Idol judge has ever performed one of her songs on the show.
"I haven't [performed before but] I was invited by the producers and I wasn't sure if I was going to do it because [time is of] the essence and I literally put everything together on Saturday, rehearsed Sunday and [some] press came in to see it at rehearsal yesterday and it was really good."
"I know you are a perfectionist [so] you'll be there after the show tonight working all night just to make sure everything is exactly right," Seacrest told Abdul.
During the interview, Abdul also confirmed that she has yet to sign a new Idol contract and is still currently unsigned for the show's next season.
"I don't know," she told Seacrest when asked whether she would be back for the show's 2010 seson. "Ryan, all I can tell you is do I ever know what's going to happen?"
"The truth of the matter is I've had blast [and] I love the show," Adbul continued. "Hopefully I'll be coming back for more but there's wonderful opportunities, thanks to the show, that are happening aand I have to weigh-in everything. You know I love what I do."
"I want this on the record: I hope you're back," Seacrest responded. "And I know [Simon Cowell] would say the same thing... he absolutely wants you back, I read it somewhere where he said he's concerned about you and [Randy Jackson] and me."
"I'm sure we'll all be there," Abdul replied. "I have a couple of weeks to make some decisions."
Abdul's new album -- her first new album since "Head Over Heels" was released in 1995 -- is expected to be released this fall.
