Has Nicole Kidman found a new leading man—or did Stephen Bing just book Australia’s most glamorous tour guide? The actress, 37, and the producer, 39—who denied a romance after being spotted together several times in L.A. recently—spent much of the weekend of March 11 to 13 by each other’s side in Sydney. But the two “are nothing more than good friends,” says Kidman’s Aussie rep Wendy Day. “He came for business and looked up Nicole. She showed him around.” On March 11 Kidman and Bing lunched at the Pier Restaurant, then dined at Aria, which overlooks Sydney Harbor, with a group including Kidman’s younger sister Antonia and her husband, Angus. The next day, the two hit the Royal Sydney Golf Club before eating at Icebergs, a Bondi Beach restaurant. And on March 13 Bing joined Kidman, her son Connor, Antonia and Angus aboard Kidman’s yacht Hokulani. But Kidman’s hospitality only extends so far—though she owns a mansion in a Sydney suburb, Day says Bing bunked at a hotel.
