Katy Perry on American Idol: Pre-Recorded "Part of Me" Performance Booed By Audience

Katy Perry performed on American Idol Thursday night.

Sadly, it was pre-recorded, leading to a chorus of boos from an audience that was beyond pumped for her to treat them to a live rendition of "Part of Me."

While awaiting the week's American Idol results, the crowd was screaming and squealing in anticipation of Perry, one of the biggest stars in music today.

For whatever reason, the stage manager and audience coordinator refused to let the crowd in on the secret that the performance was actually pre-taped.

According to E! Online, they kept teasing enraptured fans, saying, "Should we tell them? Do you want to tell them? OK, let's just let it be a surprise."

That "surprise" sucked royally. Disappointed Katy Perry fans began booing and being vocal about their disapproval of only seeing a pretaped performance.

Pretty weak for sure. Why not just say it up front? Anyway, you can still watch Perry's pre-taped rendition of "Part of Me," her latest hit, after the jump:
