Susan Sarandon spent 21 years in a relationship with fellow Oscar winner Tim Robbins and they had two children.
But they never got married.
In a new video for the Human Rights Campaign, Sarandon makes clear that she thinks same-sex couples should have the same option of getting married or not as she and Robbins did.
'While marriage might not be my thing, if it's your thing you damned well ought to be able to have it - equally and unequivocally.
'The America I want to live in celebrates diversity and believes in equal rights for all families no matter what they look like.'
