Katy Perry  stripped down like we've never seen before at the 2014 Billboard Music Awards on Sunday night. The pop songstress wore a sheer body suit covered in crazy drawings while performing "Birthday," which was pretaped at her Prismatic tour in Newcastle, England, earlier this month. Katy rocked her bright green hair while putting an excited fan in a throne and a princess crown on stage and then floated away with a bouquet of balloons in hand. Basically, it had everything you could ever dream of — and some things you never could have imagined. If this isn't enough of Katy's crazy fun for you, check out some of her most insane tour wigs (so far) .
