Keith Urban Opens Up About Daughter Sunday's Name

"Particularly when you don't have someone in your life ... in my experience, Sunday was the loneliest day," Urban, 41, tells Ellen DeGeneres on an episode of her talk show set to air Wednesday. "It went from being sort of the most dreaded day of the week for us to being the most joyous day, because we just had a family."
Although Urban and his wife Nicole Kidman are Aussies, the country musician says their nearly 9-month-old daughter – who is being raised largely in the couple's adopted hometown of Nashville – might just develop a unique twang.
He tells DeGeneres, "I think she may say, 'Good day, ya'll.' A nice mix."
