Director Michael Moore has reportedly filed for divorce from his wife of 21 years.

The Fahrenheit 9/11 filmmaker moved to end his marriage to producer Kathleen Glynn last month (Jun13) after filing papers in Antrim County Circuit Court, Michigan.

In the documents, it is alleged the pair has been living apart and there is "no reasonable likelihood that the marriage can be preserved", according to local news site MLive.

The couple wed in 1991. They have no children together.
