Perhaps her most famous relationship, both professionally and romantically, was with Woody Allen. Their bond began in the late 1960s with the Broadway play Play It Again, Sam, quickly evolving into a foundational partnership that would define a significant era of American cinema.
Allen often credited Keaton as his muse, directly shaping characters like the iconic Annie Hall, who mirrored much of Keaton’s own endearing quirks and fashion sense. Their on-screen chemistry was electric, translating into classic films like Sleeper, Manhattan, and the Oscar-winning Annie Hall. Off-screen, their relationship was intellectual, stimulating, and deeply affectionate, though ultimately not leading to marriage. Keaton herself spoke warmly of Allen, acknowledging the profound impact he had on her life and career, describing their connection as one of the great loves of her life.

Keaton played Louise Bryant, the passionate journalist and activist, opposite Beatty’s John Reed. As their characters fell in love on screen, a real-life romance blossomed behind the scenes.
Despite the strong connection, their relationship was brief and complex, with both actors at very different places in their personal lives and careers.
Al Pacino

Diane Keaton’s relationship with Al Pacino was another defining chapter in her life, born out of the intense collaborative environment of The Godfather trilogy. Their on-screen portrayal of Michael Corleone and Kay Adams, a love story tragically intertwined with the dark world of the Mafia, spilled over into a passionate, off-screen romance that went on-and-off for several years. Keaton and Pacino’s connection was often described as tempestuous and deeply felt, reflecting the dramatic intensity they both brought to their craft.
Keaton called Al Pacino the love of her life, admitting that she wanted to marry him and have children, but he wasn’t ready. Despite the breakup, the two maintained a strong friendship, and their mutual affection lasted until the end of her life.
