Zac Hanson Welcomes Second ChildMMMbaby! Although we still think of him as the adorable kid behind the drums in 90s boy band Hanson, the group's youngest member, Zac, is all grown up and has the kids to prove it.

Hanson, 25, and his wife of four years, Kate, welcomed daughter Junia Rose Ruth on Wednesday. The 8 lb., 7 oz. baby girl joins the couple's son, Shepherd, 2 1/2, and six cousins, the children of Hanson bandmates and brothers, Isaac and Taylor.

Zac told PEOPLE of his daughter, "We couldn't imagine a better Christmas gift than this sweet little girl."
