And during the Monday, May 19 episode of theArmchair Expert with Dax Shepardpodcast, Shepard recalled his own experiences with Ledger. "I feel obligated to say that I knew him a little bit when he was getting sober, and I don't know that I've ever fallen in love with somebody so quickly," the presenter said of the actor. "This is one of the most special boys I've ever met, and I can feel the weight of the world on him in a very special way that kind of broke my heart. I was very, very sad, and I thought he was just so special." Jeff Kravitz/FilmMagic Audibly emotional, Williams replied, "So special, so special, thank god there's Matilda." Shepard described Ledger as "this heart here that's just leaking out everywhere," to which Williams replied, "Yeah, an incredible sensitivity." Williams and Ledger welcomed their daughter Matilda in October 2005 while publicizing their Oscar-winning filmBrokeback Mountain. The pair met on the set of the Ang Lee film and fell for each other immediately. "We had a baby. But I suppose maybe it's a good thing about being young is that you don't have so much life experience that you can contextualize things," Williams said of that period. "So you're really just going with the flow."

TheDawson's Creekalum, who alsoshares three childrenwith her partner Tony Kail, discussed her approach to balancing children and her career. "Kids are such great life checkers," she mused. "They force you to put your best self in front of them. You can't abdicate your life and your work and your own desires, but you do have to put them in check and figure out which master you're going to serve." Williams went on to note that she doesn't believe you can have it all in work and parenthood, all of the time. "You can't be equally good at [everything] at the exact same time, and you have to allow for that give and take, but then also replenish the other things," she explained. "If you have a big period of being at home, you need to go back to what you've left unattended and put some light over there. So I think it's just this constant back and forth, but making sure that you don't leave one of them unattended for too long," she concluded. Read the original article onPeople
