Heath and Michelle split

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.
