Gurl is still up in the studio, working on her 14th studio album, of course!
The two recently teamed up in Kelly's hometown of Chicago, while Mz. Carey was in town for Idol auditions, to lay down their vocals on Thursday!
Check out the pic Mimi tweeted of the two in action (above)!!
Two vocal legends, that’s for sure!
As for what we can expect from Mariah’s upcoming album?
