Arrival Date: Mar. 3 It's...a girl! Her name is Billie Beatrice. And baby makes...three. This is the first child for the Grey’s Anatomy star and his actress wife. Birth announcement: “Mother, father and daughter are doing great,” their publicist confirmed to the Associated Press. And what about the new baby's moniker? Dane told Jimmy Kimmel last month that, though they’ve chosen a name (which they haven't yet revealed), “Rebecca wants to wait to see her before we start calling her it. You want to make sure it sticks.”
