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.
Williams' publicist, Mara Buxbaum, told E! News she would not be commenting on the matter.
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.
The two first met back in 2004, while filming Ang Lee's trophy magnet of a film and, per costars, merged their two trailers into one almost instantaneously.
"I remember being at rehearsal and seeing the two of them sort of like googly-eyed looking at each other," costar Jake Gyllenhaal told Oprah Winfrey in the wake of the film's release.
"There were sparks immediately," fellow star Anne Hathaway said at the time.
The couple was rumored to have tied the knot in a below-the-radar civil union earlier this year, though legal documents for the alleged vow swap never surfaced, and reps for the couple, per usual, failed to comment on the speculation.
Both Ledger, 28, and Williams, who turns 27 next week, have been keeping plenty busy professionally over the past few months.
Williams, who rose to fame as Jen Lindley in Dawson's Creek, has spent the past few months in London filming the drama thriller Incendiary with Ewan McGregor. Ledger, meanwhile, has traded one Gyllenhaal cohort for another, working opposite sister Maggie and Christian Bale in the next Batman installment, The Dark Knight. That production wrapped up in the Windy City last Monday.
