Nicole Kidman and Keith Urban have confirmed media reports they have returned home to Australia to marry. The Moulin Rouge actress is expected to exchange vows with country singer Urban at Sydney's Mary MacKillop chapel on Sunday before jetting off to honeymoon in Fiji. The happy couple say in a statement: "We are very happy to be back in Australia. We have come home to celebrate our wedding with our family and friends." Pictures broadcast on Australian TV showed Kidman leaving her private jet in Sydney early yesterday morning, but New Zealand-born Urban was not seen in the footage. Kidman's mother and father have already visited their daughter at her Sydney home, and the property is protected from paparazzi photographers by tight security. More than 200 guests are expected at the ceremony, including Naomi Watts, Hugh Jackman, Russell Crowe and Baz Luhrmann. All guests have been asked not to buy the couple who has everything a gift, but to donate money to charities they support. Kidman has reportedly booked out the entire Wakaya Club Resort in Fiji, where Rolling Stones rocker Keith Richards was staying when he fell from a tree and injured his head.
