Katy Perry: Beyonce's Song Isn't "Iconic"

Is she throwing shade?

Fresh off of performing her own version of Jay-Z and Kanye West's "Niggas in Paris," Katy Perry is now revealing that she and best friend Rihanna have a collaboration in the works.

But there's one duet she doesn't want theirs to sound like - and it featured Jay's wife.

While over in London, Perry told BBC radio station Radio 1, "[Rihanna & I have] 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. I want it to be like that Eurythmics and Aretha Franklin song 'Sisters Are Doin’ It For Themselves,' not like [Shakira and Beyonce Knowles'] 'Beautiful Liar.' I definitely want to do something that is so iconic. How disappointed would you be if that song came out and it’s no good? Sometimes you have to wait for greatness."

Rihanna echoed the same sentiment to Access Hollywood recently, saying, "We have been working on this for years. We still are trying to make a song together. She is one of my favorite musicians, as well as one of my favorite people in the industry. She’s very uncalculated, very sure of herself, and that’s something very rare in this industry to find. The song will probably come out in a while. I won’t say that it’s happening right now, but it’s going to happen.”

Granted, "Beautiful Liar" wasn't exactly groundbreaking, so maybe Perry isn't throwing shade and is simply setting a higher goal.
