Michelle Williams is one of Hollywood's most private celebrities, but she's always been incredibly forthright about the ups and downs of being a single mom to 11-year-old daughter Matilda. Since the death of Heath Ledger in 2008, Michelle's former boyfriend and Matilda's father, the Certain Women actress has been raising their child on her own and discussed how it's affected her dating life in the latest issue of Porter magazine. Luckily, Michelle has the support of close friend Busy Philipps, whom she shares a hilarious (or hilariously depressing?) anecdote about, and is creating plenty of Oscar buzz for her role in Manchester by the Sea. Check out what she had to say ahead, and to see the full interview with Michelle, buy the latest issue of Porter, which hits stands on Dec. 2.
