Lady Antebellum's Hillary Scott is one busy lady these days.   Not only is she's busy with Charles Kelley and Dave Haywood promoting the release of their new album "Own the Night," but the trio is planning an upcoming tour.  Oh yeah, and there's that wedding thing, “[Chris] is actually talking to the planner more than I am right now, which I’m very very thankful,” Hillary told E! News last week, “I’m a lucky girl.”   While Hillary doesn't seem to mind Chris' approach, she is questioning the groom's cake, “We did ask him, ‘What kind of groom’s cake do you want?’ and he goes, ‘I really want a cheeseburger [cake].’” Read all about it here.   Count on Charles and Dave to lend a hand, with Charles acting as the deejay and Dave suggesting the tunes, “Get them back up with ‘YMCA.’”   No word on when the nuptials will be, but you can bet it will be a party!  http://www.youtube.com/watch?v=v_yTphvyiPU
