Chris Tyrrell, Hillary Scott's husband and Lady Antebellum's longtime drummer, is stepping away from the band for the time being to take care of the couple's children. Hillary tells People Chris will be "holding it down as Dad, hero" at home as she and bandmates Charles Kelley and Dave Haywood head out on their "Summer Plays On Tour" with co-headliner Darius Rucker. Scott says the two came to the agreement together, saying, "It was one of the easiest decisions we've ever made and the peace that we've felt since we made it has just been continual proof of it being the right call."Hillary and Chris are the parents to 2-month-old identical twin girls, Betsy Mack and Emory JoAnn, and 4-year-old daughter, Eisele Kaye.
