ET Rewind: Heath Ledger & Michelle Williams

Michelle Williams is up for an Academy Award for her performance in My Week with Marilyn, but her celebration remains bittersweet without the love of her life, Heath Ledger, by her side.

It was four years ago that Heath shockingly passed away from an accidental overdose of prescription drugs. Back in 2006, both Heath and Michelle were nominated for their performances in Brokeback Mountain, and it was incredible to see the loving couple arm-in-arm on the red carpet, representing the movie in which they fell for each other.
