Katy Perry Instagram – Happy 15th anniversary to my first musical child, One of the Boys! (I know omg the passing of time is WILD) She may be a young teen but has always had a bit of an attitude🤘🏻😉 Thank you to all the KCs who have stuck around since the Warped and Hello Katy days… tbh I still think of myself as One of the Boys 🤸🏻🎸🍓 #OOTBCoveralts
