29. Michelle Williams
Michelle Williams is making her debut on the PopSugar 100 after a year of focusing on her career and daughter Matilda. When she wasn't adorably strolling around Brooklyn with Matilda, Michelle was out promoting Shutter Island and filming Blue Valentine, which she showed off just a few weeks ago at Cannes with costar Ryan Gosling. Michelle opened up about losing Heath Ledger for the first time in an interview with Vogue, in which she also revealed that she'd parted ways with Spike Jonze.
