In that now-infamous interview with Bravo's Andy Cohen, in which Rihanna may or may not have been tipsy, she revealed a tidbit about her dream collaborators: the Queen of Pop  and her very own BFF Katy Perry!

Cohen asked RiRi if she'd ever want to work with Madonna. The Bajan beauty replied, “That would be so sick! I’d love it.” We can totally see that working, too: The 'S+M' singer with the author of the infamous 'Sex' book? Get Madge on the phone!

One person Rih isn't keen on working with -- or even listening to? Carly Rae Jepsen. She explained, “I don’t listen to pop music in the car,” she said. “I like to get crazy and you can’t get too crazy to ['Call Me Maybe'].” Fair enough!

A fan actually suggested the collaboration with Perry, and RiRi was gung-ho about it, despite Perry being as pop as pop gets. We guess that disproves the rumor of a rift in their friendship (Perry was rumored to be unhappy with RiRi's reunion with Chris Brown). “Definitely Katy Perry still," Rihanna enthused. "I don’t know why we haven’t gotten this done yet!”

Rihanna and K.P. have been tossing around the idea of a duet for a while -- and it actually, however briefly, landed Perry in hot water. “ We've collaborated on a lot of things, but just not songs yet,” Perry said back in March. “It’s one of those things that’s got so much build up that we have to deliver. I want it to be like that Eurythmics and Aretha Franklin song ‘Sisters Are Doin’ It for Themselves,’ not ‘Beautiful Liar.’” (We bet living legends Shakira and Beyonce had a hearty eyeroll at that comment, from which Perry later backtracked.) “But I definitely want to do something that is so iconic," she added. "[Rihanna's] 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.”

Welp, we're still waiting. Should we stop holding our breath yet?
