Katy, nor K$, write their own songs. This became obvious to me when Pitbull won a Billboard Music Award this year for Timber and he didn't even thank K$ once in his acceptance speech. Dr. Luke & co are the masterminds, Katy & K$ are merely the puppets.
Not that there is anything wrong with that since I pray that Gaga will become a puppet like back in 2009 because nowadays she's horrible.
