Katy Perry and Rihanna officially announced they’ll be working together! But lots of fans were sad when RiRi told them not to expect the results anytime soon.








And here’s why. Katy said: “It’s one of those things that’s got so much build up that we have to deliver…I definitely want to do something that is so iconic.”








Plus, Katy explained, “We’re both busy but we planted the seed two years ago. How disappointed would toi be if that song came out and it’s no good?”






“Sometimes toi have to wait for greatness.”
