Neil Young is reportedly splitting from his wife after more than 36 years.

The Harvest singer has filed for divorce from Pegi Young, reported Rolling Stone.

He filed papers in their hometown of San Mateo, California last month and a hearing will take place in December.

Neil and Pegi tied the knot in August 1977 so they were nearing 37 years of marriage.

As well as raising two children together, they collaborated on music, with Pegi providing backing vocals for her husband and the singer accompanying her on guitar on her own tracks.

Neil, 68, has also penned songs about their romance, including Unknown Legend and Such A Woman.

The couple also co-founded a school in 1986, after being inspired to do so by the lack of educational opportunities for their son, who has cerebral palsy.
