Her heart may belong to Russell, but Katy Perry’s studio time goes to Rivers. Weezer frontman Cuomo announced recently in a buzznet interview that he’s gearing up for a collaboration with the girl-kissing, Vegas-loving pop tartlet: “We’re writing together next week. Can’t wait!”

Weezer’s upcoming November 3 release Raditude is, of course, already in the can, so whatever the fruits of their labor (and as we all know,  Perry hearts fruit), they’ll probably end up on her next album. And Rad already has a host of its own collabs, including Lil Wayne and members of All-American Rejects.

Who else would you like to see pair up in the pop and rock worlds, Music Mixers? Kelly Clarkson and her beloved Kings of Leon? Jack White and his Nashville neighbor Taylor Swift?
