Apparently, there's one person Heath Ledger can quit.

Ledger and his fellow Brokeback Mountain Oscar nominee--and parent--Michelle Williams have ended their three-year relationship together, both People and Us Weekly report.

According to both reports, the split took place several weeks ago and was completely amicable. Reps for the couple have so far not commented on the possible separation.

The press-shy duo has spent the past few years domesticating in Brooklyn along with their nearly two-year-old daughter, Matilda Rose, who was born in October 2005.
