Katy Perry has always walked a fine line between candy-colored princess and naughty nymph, so it’s not really surprising that she’s still mixing the two in her new Prismatic tour.

The pop star has had us all singing along to “Roar” for months now, and her tour opened to successful reviews. With no shortage of breathtaking stage effects and costume changes, Perry is staying within her comfort zone for a whirlwind world tour, complete with a fireworks show and 3-D projections.

The tour isn’t just about the music and light show, however; Perry has partnered with Staples to help fund DonorsChoose.org, a program that aids teachers get what they need for classrooms on a seriously tight budget.

“I’m glad to partner with Staples on my Prismatic World Tour to raise awareness and funds for DonorsChoose.org, and to remind my fans that a small gesture can have a huge impact on the very basic materials classrooms need for teachers to help students reach their full potential,” said Perry.

Perry may be a worldwide pop star, but that doesn’t mean she’s got a big ego; during a recent performance while on tour, she accidentally smacked herself in the face with the mic, then called herself out on it with a laugh.

“I just hit myself in the face with my own microphone. f that’s not a humbling move, I don’t know what is.”
