Nicole Kidman and Keith Urban peaked the curiosity of their fans when the celebrity couple named their daughter Sunday Rose following her birth on Monday. There was no explanation so it fell to Kidman’s father to explain the name – and it turns out the infant is named after Sunday Reed, an Australian patron of the arts with a tumultuous life story.

“I have read a bit about Sunday Reed and her husband John — she was a key mover and shaker in the arts around the beginning of the century,” Antony Kidman, told The Daily Telegraph of Sydney. “The name Sunday struck me as being a nice name for a woman, so my wife and I mentioned it.”

Sunday Reed came from a wealthy family and in the 1930s, during the height of the Great Depression, she and her husband turned their home into a haven for artists. One of those artists was the late painter Sidney Nolan, who became entangled in a decade-long menage-a-trois with the Reeds and who made Sunday Reed into his muse.

Oscar-winner Nicole Kidman, 41, and Grammy-winning country singer Keith Urban, 40, both were raised in Australia. They recently attended an exhibition of Sidney Nolan’s art in the state of New South Wales, the Daily Telegraph reported. A quote from Nolan posted at the exhibit read: “When you are young you are given a good view of life, because of your closeness to birth,” according to the newspaper.

Sunday Rose Kidman Urban is the first biological daughter for Oscar-winner  Kidman, star of “The Golden Compass” and “The Interpreter.” The baby, who was born in the United States, reportedly got her middle name from Urban’s grandmother.
