Mad Men star Jon Hamm has split from his partner of 18 years.
Hamm and Jennifer Westfeldt confirmed the news to American website, People.
In a statement, they said: "With great sadness, we have decided to separate, after 18 years of love and shared history.
"We will continue to be supportive of each other in every way possible way moving forward."
In March this year, Hamm's representative confirmed the star had completed a stint in rehab for alcohol abuse.
The couple started dating in 1997, but never got married.
Hamm rose to fame for his role as Don Draper in AMC Drama's hit show Mad Men, which came to an end earlier this year after seven seasons.
