You Oughta Know artist, Unplugged veteran and history maker — remember how she performed pregnant? — and one-half of the Grammy Award winning duo Civil Wars Joy Williams has added “Mother” to her already impressive résumé. Williams and her husband, the Civil Wars’ manager Nate Yetton, brought a baby boy into the world on Saturday. Welcome, Miles Alexander! “Now I really know what love at first sight means,” she gushed on Twitter. “All happy and healthy.” A hearty congrats to all!
