Casey Affleck's wife Summer Phoenix has filed for divorce.
ET reports that Phoenix cited "irreconcilable differences" in the petition filed Monday with the Superior Court of California in Los Angeles.
The couple separated in November 2015 after almost 10 years of marriage and 16 years together, announcing their split publicly in March 2016.
Phoenix is the younger sister of Joaquin Phoenix, who worked with Affleck on the 2010 mockumentary I'm Still Here.
The pair welcomed their first son in May 2004 before wedding in June 2006. Their second son was born in Jan. 2008.
Reps did not immediately respond to USA TODAY for comment.
