Singers Katy Perry and Rihanna are planning to record a girl power duet. The pop stars are working on an "iconic" collaboration, but are not in a rush to record it.
"We've collaborated on a lot of things, but just not songs yet. It's one of those things that's got so much build up that we have to deliver," dailystar.co.uk quoted Katy Perry as saying.
"I want it to be like that Eurythmics and Aretha Franklin song Sisters Are Doin It for Themselves, not like (Shakira and Beyonce song) Beautiful Liar," she said.
"But I definitely want to do something that is so iconic. (Rihanna) kind of busy too. We're both busy but we planted the seed two years ago. How disappointed would you be if that song came out and it's no good? Sometimes you have to wait for greatness," Perry added.
