Lady Gaga Tapes ‘American Idol’ Performance

'You're my little monsters, and you're the reason we all work so hard for our dreams,' Gaga said from the stage at the Nokia Theatre.

While the viewing public tuning in to “American Idol” on Wednesday night caught Siobhan Magnus getting the ol’ heave-ho and Rascal Flatts, Shakira and Lady Antebellum taking the stage, one performance at the Nokia Theatre didn’t make it on to the small screen: [artist id="3061469"]Lady Gaga’s[/artist].

After Wednesday evening’s elimination show wrapped, Gaga took over the Nokia to tape an “Idol” performance, which Gaga has tweeted will air on Wednesday but at press time had not been confirmed by “Idol” reps. But audience members were still holding steady in their seats, and many have since committed their thoughts and reporting to the Web (stop reading now if you want to experience the Gaga-tude spoiler-free whenever the perf hits the airwaves).

By all accounts, it was a predictably massive undertaking, requiring an hour to re-set the stage, the introduction of a giant fire-spewing angel and three full performances of a “Bad Romance”/”Alejandro” medley.

“I just want to say thank you,” Gaga told the crowd before launching into the number a third time, according to a write-up on EW.com’s PopWatch blog. “You’re my little monsters, and you’re the reason we all work so hard for our dreams.”

The taping got started directly after the end of the live show. The “Idol” crew wheeled on that huge metallic angel, two black metal trees and a few park benches built of bloody razor blades. “[T]he entire set looked like the S&M version of ‘Alice in Wonderland’ meets the cemetery scene from ‘Phantom of the Opera’ populated by half-naked nymphs from ‘Midsummer Night’s Dream,’ ” reported Zap2It.com.

The first run-through was Gaga-free — just the band and her backup dancers. Gaga joined in for the second go.

“There were eight hard-bodied male dancers scantily clad in what looked to be black Spanx — each guy wore a black glove as well, à la Michael Jackson,” wrote HollywoodLife.com. “They writhed and gyrated to the music before the lady herself took to the stage wearing a black bra, garters and underwear covered by some filmy gauze. Her butt cheeks were on full display, but at least she kept her girls covered!”

Gaga began the performance sitting at the piano for a slowed-down take on “Bad Romance.” That tune then morphed into a raucous version of “Alejandro.” The angel shot flames from its wings during each utterance of “Alejandro” in the chorus.

“Fight and push harder for what you believe in, you’d be surprised, you are much stronger than you think,” Gaga tweeted last night. “Alejandro. American Idol.”
