Grieving Naomi Watts was too upset to talk about the death of ex-boyfriend Heath Ledger on Saturday as she went shopping in Santa Monica with her six-month-old son, Alexander. Wearing dark glasses, a sombre looking Watts told photographers: “I really don’t want to talk to you guys right now.” The couple who had dated for nearly two years in 2002 remained good friends after they broke up. Naomi joined Heath's family, including former fiancee Michelle Williams and daughter Matilda, 2, at a private memorial service held in Beverly Hills on Saturday evening.
