Shortly after, a recently-divorced Birkin met Serge Gainsbourg, a French singer, songwriter, and director 18 years her senior, while on the set of Slogan. The two were together for over ten years but never officially got married. In 1969, they came out with a scandalous song, “Je T’aime…Moi Non Plus,” and a debut album titled Jane Birkin/Serge Gainsbourg.
