Michelle Williams is opening up about her memories of Heath Ledger. During Monday's episode of the " Armchair Expert with Dax Shepard " podcast, Williams, who shares daughter Matilda with the late actor, reflected on their time together after Shepard shared his own memories of Ledger.

Williams replied, in a whisper, that Ledger was “so special,” repeating it a few times. “Thank God there’s Matilda, ” she added, referring to her and Ledger’s now 19-year-old daughter.

Williams and Ledger met while working on the Ang Lee-directed gay cowboy romance Brokeback Mountain, and welcomed their daughter in October 2005.
