Sunday Rose Kidman Urban has only been in the world for a day, and already the world has a million questions about her. The first inquiry: Where did she get her name? One source said that Urban penned a song called "Sunday," about his unborn baby girl, as the couple opted to find out the sex of the child, and the song is the inspiration for the name. Another rumor was that "Sunday" was a stab at Scientology, being the day that a Catholic Kidman gave up while married to her Scientologist ex, Tom Cruise. A recent report from the Herald Sun even has a radio personality claiming the Kidman/Urban clan stole her baby's name. Never fear, mom and dad, Kidman that is, stepped in and cleared up the baby name frenzy. Antony Kidman told The Daily Telegraph that he and his wife suggested the name Sunday. "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," he said. "The name Sunday struck me as being a nice name for a woman, so my wife and I mentioned it. The pathway toward the name Sunday Rose winds even more than the mere suggestion by the Kidmans. Sunday Reed had a relationship with the artist Sidney Nolan, and a January visit to a Nolan exhibit sealed the deal. The exhibit featured a quote from Nolan about birth: "When you are young you are given a good view of life, because of your closeness to birth." Rose was apparently chosen in honor of Urban's late grandmother. Sunday Rose could be fueling a different frenzy—that of her father's single, "You Look Good In My Shirt," which has reached No. 9 on R&R and Mediabase this week. The single is available on iTunes and will be included in the re-release of Urban's Greatest Hits: 19 Kids.
