LATEST: Nicole Kidman celebrated her troubled husband Keith Urban's 39th birthday with her favourite girls - best friend Naomi Watts and sister ANTONIA HAWLEY. Pregnant TV presenter Hawley jetted to Hollywood from her native Sydney, Australia to help her sister cope with what should have been a big celebration yesterday (26OCT06) - the first birthday the couple would have celebrated as husband and wife. Urban checked himself into a rehab centre earlier this month (OCT06) after revealing he was battling alcoholism. The Kidman sisters spent the day at pal Watts' Hollywood home, for what is being dubbed a "tea and tissues session" by insiders. Hawley's young son HAMISH, who accompanied his mother on the trip, helped lighten proceedings - he was seen in Kidman's arms as she left Watts' home for a waiting car late yesterday.
