Rihanna and Katy have almost collaborate on multiple times, the only difference is that their both pop star and have a much more charged scedhule than rappers. Bonnie said Katy ft. Rihanna would have happen if they didn't have a falling out earlier this year. They already wrote the song, had the demos, everyone liked the song and #BOOM Chris arrived.
She never intended to even work with Bey&Lady GaGa
