Luke Bryan on The Ellen Show

Luke Bryan has one major rule for his fans – his backside is off limits. Although the superstar singer has made a career out of shakin’ it for everybody at his concerts, he is making it clear that he wishes for everyone to leave his butt alone. Unless your name is Ellen DeGeneres of course. Ellen got to give Luke’s glutes a little squeeze, AND got him to play a new game of her’s, called “Oops, My Water Broke,” which you can watch below. Ellen, Luke, and water balloons? YES.
