"Even my tippy toes are ready," she captioned the photo. We're glad to hear that the pop star is now officially ready from head-to-toe because she did recently admit that she's a touch nervous about the performance - and who wouldn't be?!
"I'm a human...I'm nervous, duh!" she told E! News. "I'm not superhuman, I'm not a robot!" We don't blame her at all for being nervous, but she's Katy Perry, she's gonna kill it. No question about it.
As for what we can expect during the 12-minute performance, we know Lenny Kravitz will be joining her for at least a portion of it and she hinted that he's only ONE of the guests. She also says that her entrance and exit will be "superb"...weather permitting.
