R5's new song "Smile" is a total jam - we love to listen to it whenever we're feeling a little down and need a pick me up. The group is hard at work making a new awesome video for their song, including trying to learn how to sing it in reverse. The band is even challenging their fans to try and learn how to sing "Smile" backwards along with them, which isn't an easy feat. In this behind the scenes sneak peek from the making of the "Smile" music video, the band practice their "elimS" (get it?) and get to work on set. Check it out below.
