Apparently nothing according to her lawyer Michael C. Miller. "Despite tabloid speculation, Mary-Kate Olsen had nothing whatsoever to do with the drugs found in Heath Ledger's home or his body, and she does not know where he obtained them."

Sources close to Heath Ledger and Michelle Williams aren't surprised about the couple's split. "They have been broken up, on and off, since Matilda was born, and tried in many ways to make it work for her sake," says a source close to Ledger. "Matilda will remain their first priority." The day the news of the breakup surfaced, Ledger brought his mini-me to NYC's Children's Museum of Manhattan, and on September 3, Williams and her daughter were spotted at a cafe in Brooklyn. The past year or so has been filled with ups and downs, says a source, as the duo spent "a few months apart and barely spoke." "You'll see them together again," a Ledger source says of the committed parents. "It won't mean they're back on, but they'll be spending time with Matilda."
Heath Ledger was looking somber at the Venice film fest today following his split from longtime girlfriend Michelle Williams. At a news conference Tuesday afternoon promoting his new film I'm Not There, an witness described the actor as very quiet while fielding questions from reporters. "He kept his head down a lot and I think he was hoping not to be asked too much," said the onlooker. "He had his hat tipped a little low and didn't really make eye contact with anyone. You could tell he didn't want to be there." The press were only allowed to ask questions about the movie, and didn't question the actor about his recent breakup. "Heath clearly had a lot going on in his head," said the source. "Sometimes he was just staring off to the side, clearly in his own world."
Heath Ledger and Michelle Williams have called it quits on their three-year relationship. A source close to the couple says the actors "quietly and amicably split a few weeks ago... The relationship had been rocky recently. They tried very hard to make it work but finally decided to separate. They just grew apart." The couple, who live in Brooklyn and have a nearly two-year-old daughter, met on the set of Brokeback Mountain in 2005. "They have a beautiful daughter and they are both committed to being great parents," said the source. Reps for the pair could not be reached.
