Zac Brown Band member Clay Cook and his wife, Brooke Ellen, are expecting their third child. This time they are having a girl. This is rare in the Cook family, since no member of the Cook family line has given birth to a girl since the 1930's. The baby is due in the fall. "Our whole family, and especially her big brothers, cannot wait to meet her," Clay says. "I can't say how much it means, especially during this time in the world, that we can share our joy and blessing with everyone."
