At the time, the This Is 40 actor took to Instagram to share a sweet birthday tribute that she wrote for him. "Feliz Cumpleanos Luis,” Dunham captioned a picture of them both.
"When I was 3 weeks old in downtown Manhattan, I had no idea a baby was being born in England (Winchester, no less!) who would rocket into my life — wearing a lime green polar fleece snood — and challenge so many of my beliefs about myself and the world with magical abandon."
Dunham continued, "Everyone who comes into contact with you — creatively, emotionally, accidentally — is lucky. But I am the luckiest, because that snood is now in our shared chest of drawers."
