Tilda Swinton and Sandro Kopp – 17 Years

Tilda Swinton was never a woman who went by the social rules. Like the Ancient One from Doctor Strange and Lucy Mirando from Okja, her roles are always eccentric and unique. For many years, she was married to playwright John Byrne, with whom she has two children.

From the early 2000s and onwards, she started living in the same house with Byrne, the children, and her partner Sandro Kopp, a German artist. She even claimed that they were all happy together. Eventually, Byrne and Swinton split, and Byrne is now married to another woman.
