Goldie Hawn and Kurt Russell
They met while making the film The One and Only, Genuine, Original Family Band in 1967 before reconnecting on Swing Shift in 1983.
Nearly four decades later, they’re still together but have famously never married.
However, Kurt admits that his first romantic approach to Goldie had the potential to be awkward.
He recalled to Conan O'Brien: "I didn't know Goldie at all outside of having worked with her many years before.
"I just didn't know in my mind what I was going to see. She had a great body, and so the first thing that came out was, 'Man, you got a great figure'. And it kind of came out quickly and it could've been wrong and she said, 'Why thank you.'"
