His name may get top billing but Luke Bryan isn't afraid to share the stage with others. He's sung with Florida Georgia Line (and got a No. 1 song out of it), Jason Aldean and Eric Church ("The Only Way I Know" went platinum) and Lionel Richie (he won a CMT award for that). But you don't have to be famous for Luke to bring you onstage. During his performance at the 2014 iHeartRadio Country Festival in Austin, Luke brought a Make-A-Wish girl onstage to serenade her while he sang, what else, "Crash My Party."
