Abdul to Perform on Wednesday Night Idol Stage

Paula Abdul is set to sing tonight on American Idol. The live performance will be a song from her first single "I'm Just Here for the Music," from her latest album.

Abdul confirmed she is performing on Idol while on Ryan Seacrest's radio show Tuesday morning. She wasn't sure if she wanted to be on the Idol stage, but was given a last-minute offer by the show's producers. She has known since Saturday night and rehearsed on Sunday. She also told Seacrest she has yet to sign a contract for next season's Idol. Reality TV World reports:

"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.

"No Doubt" and "Daughtry" will also be performing on tonight's show. Abdul is also finally coming clean about her 12-year battle with painkiller addiction. She claims she never filmed while under the influence, nor did she use illegal medicine. Abdul's body has been put through the grinder after years of cheer leading, dancing injuries, a 1992 car crash and a 1993 plane crash. She required 15 spinal surgeries following the plane accident. Abdul suffers from reflex sympathetic dystrophy syndrome. She was diagnosed in 2005 for the condition that has left her in constant pain, chattering teeth and shingles-like lesions. Since last Thanksgiving, Abdul says she has been off medication. She is now working to relaunch her singing career.
