"@AmericanIdol What's going on? need the info!! What about this combo? : ) if we could ever get him to do it," Carey wrote in a caption for the photograph.
Kravitz appeared open to becoming an American Idol in his response to old friend Carey.
"Girl, we've known each other since we were teenagers. How fun would that be?!" he replied.
