Katy Perry: 'Part of Me' on American Idol!
“Me and 12 strong chicks dance it out military-style on @AmericanIdol tonight! Tune in to Fox at 8/7c! #PartOfMe #NightVision,” the 27-year-old singer tweeted.
Katy actually pre-taped the performance the night before after the live performance show ended.
“Has Jessica Simpson had that baby yet?! I’m getting anxious,” Katy tweeted earlier in the day.
FYI: Katy is wearing Army Surplus customized by Silvias Costumes and All Saints boots.
