NICOLE Kidman, who just finished producer Scott Rudin’s film “The Stepford Wives” – which everyone associated already labels a big-time winner – was on her way from New York where it was wrapping to L.A. where her “Cold Mountain” was premiering. But she has an interesting travel agent. She took the Southern route. Went west by way of Florida. The stop-off this weekend was in Miami to see Lenny Kravitz.
