THE mystery of Nicole Kidman's unusual name choice for her newborn daughter has been solved. The Oscar-winner's father revealed 'Sunday' was inspired by an Australian arts patron notorious for her lurid love life. Antony Kidman said the name was first suggested by him and his wife Janelle, who drew inspiration from prominent Australian Sunday Reed. '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. 'The name Sunday struck me as being a nice name for a woman, so my wife and I mentioned it,' Antony Kidman told Australia's Daily Telegraph newspaper on Wednesday. Sunday Reed lived for nine years during the 1930s in a three-way love triangle relationship involving her arts patron husband and one of Australia's best-known artists, Sidney Nolan. She eventually became Nolan's muse. Nolan is best known in his homeland for a series of stylised paintings of famous outlaw Ned Kelly, who battled police in an armoured suit and whose final days were turned into several films variously starring Mick Jagger and late Australian actor Heath Ledger, who died of a drug overdose in January. Sunday Reed was also niece of one of Australia's richest men and Nolan painted his Ned Kelly series, several of which hang in the Australian National Gallery, in her living room. The baby's middle name, Rose, is a tribute to Keith's late grandmother. Nicole's first biological child was born in Nashville on Monday and weighed 6 pounds, 7.5 ounces. Nicole and former husband Tom Cruise adopted two children, Isabella, 15, and 13-year-old Connor, during nearly 10 years of marriage that ended in divorce in 2001.                         - Daily Mail
