The couple got married in 1996
Hollywood actor Dennis Hopper, who is suffering from prostate cancer, has announced he is seeking a divorce from his fifth wife of nearly 14 years.
The star, best known for directing and starring in the film Easy Rider, has a young daughter with Victoria Duffy.
In a statement, the star said: "I wish Victoria the best, but only want to spend these difficult days surrounded by my children and close friends."
Speaking to Reuters, his spokesman said the star "wants peace and quiet".
Alex Hitz said the couple have been "having trouble" but are currently still living together as their home arrangements are being worked out.
The actor filed his petition to divorce Duffy at Los Angeles Superior Court on Thursday.
Hopper, who married Duffy in 1996, cited "irreconcilable differences" for the split and is seeking joint legal and physical custody of the couple's daughter, six-year-old daughter, Galen.
The star, who was diagnosed with cancer in September, has just begun a new round of chemotherapy drugs.
His eldest daughter Marin, said in a statement: "Dennis is brave, and he is fighting a hell of a battle."
Hopper, who received two Oscar nominations for Easy Rider, also starred in Rebel Without a Cause, Giant, Apocalypse Now and Blue Velvet.
