Oscar-winner Michelle Williams has split from her indie rocker husband Phil Elverum just months after they wed in a secret ceremony last year.

The couple are reportedly on good terms and the break up is amicable, according to People magazine.

Elverum is a member of the indie rock band The Microphones and Mount Eerie and was previously married to Canadian musician Genevieve Castree, who died from pancreatic cancer in 2015.

Williams was in a three-year relationship with Heath Ledger, who died in 2008, leaving behind their young daughter Matilda, who is now 12.

In an interview with Vanity Fair last year, Williams spoke about her relationships with both Elverum and Ledger.

"Obviously I've never once in my life talked about a relationship," she said. "But Phil isn't anyone else. And that's worth something.

"Ultimately the way he loves me is the way I want to live my life on the whole. I work to be free inside of the moment. I parent to let Matilda feel free to be herself, and I am finally loved by someone who makes me feel free."

Now it seems she may be heeding her own advice after she offered this piece of wisdom in the interview.

"Don't settle. Don't settle for something that feels like a prison, or is hard, or hurts you. If it doesn't feel like love, it's not love."
