Nicole Kidman celebrated her 40th birthday on the beach in Sydney, Australia on Saturday (16Jun07) with a party thrown by her friends. With husband Keith Urban expected to join the actress for her actual birthday date on Wednesday (20Jun07), it was left to family and friends to help The Hours star celebrate her last weekend as a 30-something on Bondi Beach. It was largely an all-girl's affair as Kidman's sister Antonia and their mum Janelle invited 30 of the star's closest pals from Australia and Hollywood to join them at Bondi Icebergs for a pre-birthday dinner. And Kidman, who will also celebrate the first anniversary of her marriage to Urban later this summer (07), certainly isn't feeling sore about hitting 40. In a recent interview, she said, "It feels just right. I don't feel what I thought that wretched age was going to be like. I have done a lot of things and it has been full up to this point, especially the past few years, so I am grateful for that."
