Michelle Williams

For many fans, Michelle Williams will forever be Jen Lindley of the much ladored WB teen drama Dawn's Creek. But like co-stars Joshua Jackson and Katie Holmes, Michelle has made quite a name for herself beyond the Creek. Her biggest breakthrough probably came in the critically acclaimed Brokeback Mountain which earned Michelle an Oscar nomination and was also where she fell head over heels for co-star Heath Ledger. Not long after filming finished, Michelle and Heath began living together and were expecting their first child, Matilda Rose. Then in 2007, the couple split only four months before Heath was found dead in Manhattan while Williams and Matilda were filming in Sweden. Michelle continued working, including the indie hit Blue Valentine which earned Michelle another Academy Award nomination, while being a young single mother and one of Hollywood's most sought after leading ladies.
