Besides being Hilary Clinton's number 1 boo, we haven't seen much of new KP music since she dropped Prism three years ago.
However, Katy's most recent Insta Stories video might be a hint that she's back in the studio, working on some new music!
She also posted a second video that has a slower song playing in the background. The video is captioned, "We've got another one! INSTRUMENTS! VOCALS!!"
