Heath Ledger and Michelle Williams are the latest celebrity couple to call it quits. Although their relationship has supposedly been rocky for awhile, the split is amicable, a source told People.
The two met and began dating while filming Brokeback Mountain in 2004. "There were sparks immediately," costar Anne Hathaway said of the pair.
In October 2005, Ledger and Williams welcomed a daughter, Matilda.
