Luke v. Lady A Dance Off!
Luke Bryan invited Charles Kelley and Dave Haywood from Lady Antebellum (who, up until this week, have been without third member Hillary Scott, who was on maternity leave) onto the stage to join him on his hit "Do I", which Charles and Dave co-wrote with Luke back in 2008. Ironically, Lady A and Bryan, nearly six years later, are two of the hottest acts in country music.
