Michelle Williams had a major year, with her Blue Valentine role opposite Ryan Gosling earning her an Oscar nod. The actress's obvious chemistry with Ryan was buzzed about all awards season, but there is no real-life romance there, and she took her longtime best friend, Busy Philipps, as her date to the Academy Awards. Michelle spent most of the year single, though she recently stepped out with her new guy, Jane Eyre director Carey Fukunaga. Her daughter, Matilda, is still the center of her life, and Michelle touched on her experience as a single mom and Heath Ledger's passing during a December interview with Nightline, marking one of the first times she's spoken about the loss. Michelle is lightening things up a bit after heavy Blue Valentine, having signed on for a role in Oz: The Great and Powerful as Glinda the Good Witch, and we'll see her as Marilyn Monroe in My Week With Marilyn, out in 2011.
