Coping hasn’t been easy for Michelle Williams in the wake of Heath Ledger’s fatal drug overdose. And it hasn’t been easy for their daughter, Matilda, 3, either. Vogue reports that at her local coffee shop, a little girl asked Michelle, “What’s her name?” “Matilda,” she answered. According to Vogue, “The girl said to Matilda, entirely innocently, ‘What’s it like being famous? Are you so sad that your daddy died like Michael Jackson?’ . . . ‘That girl was 6,’ Williams says without rancor.” Williams, who was nominated for an Oscar for “Brokeback Mountain,” had a romance with director Spike Jonze after her split from Ledger, but they are no longer together. “The timing was impossible,” she told the magazine. “I thought falling in love again was the only thing that was going to save me from the pain. This erroneous idea: It just makes things more complicated.” And dating when you have a kid? “I obviously don’t know how to do it.”
