Diane Keaton’s Dating History: Inside Her Relationships With Woody Allen, Warren Beatty, and Al Pacino

Diane Keaton’s dating history has long fascinated Hollywood fans. The Oscar-winning actress, who died at 79 in October 2025, never married but had three highly publicized romances with some of the most influential men in entertainment — Woody Allen, Warren Beatty, and Al Pacino. Each relationship shaped her life in unique ways and reflected the fiercely independent spirit she maintained throughout her career.

Keaton’s love life was unconventional by Hollywood standards. She chose not to walk down the aisle and instead embraced single motherhood later in life, adopting two children — daughter Dexter and son Duke — in her 50s. Despite this, her romances with three major Hollywood icons continue to be a defining part of her story.

“Annie Hall” was loosely based on Keaton.

From Woody Allen to Al Pacino: Diane Keaton’s Famous Romances

Diane Keaton’s first major relationship was with director and screenwriter Woody Allen. The two met in 1969 when Keaton auditioned for his Broadway play Play It Again, Sam. Allen wrote in his memoir that he was instantly captivated by her wit, originality, and charm. Their chemistry translated on screen, most memorably in Annie Hall (1977), a film many believe was inspired by their real-life romance.

The couple lived together in Allen’s Manhattan penthouse and became one of the most talked-about creative partnerships of the 1970s. Although they eventually broke up when Keaton returned to California for a role in The Godfather, their bond remained strong. Keaton continued to star in several of Allen’s films and publicly supported him decades later amid controversy, writing on X in 2018, “Woody Allen is my friend, and I continue to believe him.”

After her split from Allen, Keaton was linked to actor and director Warren Beatty. They met on the set of Reds (1981), in which Keaton starred and Beatty directed and produced. Their relationship, though brief, was passionate and intense, and Beatty’s larger-than-life personality contrasted with Keaton’s quirky charm. While the romance ended, both spoke fondly of each other in later interviews, and Reds went on to become one of the most acclaimed films of Keaton’s career.

Keaton’s most significant relationship came in the late 1970s and early 1980s with Al Pacino, her co-star in The Godfather trilogy. Their on-and-off relationship spanned years, marked by deep affection and mutual respect. Keaton later revealed that she proposed marriage to Pacino, but he declined, and their romance eventually ended. Despite this, they remained close friends for decades, often praising each other’s work and influence.

Diane Keaton’s Choice to Stay Single and Embrace Motherhood

Despite three high-profile romances, Diane Keaton chose a life without marriage — a decision she said she never regretted. In interviews, she described herself as “not cut out” for traditional domestic life, even though she deeply valued love and companionship. “I didn’t want to give up my independence,” she once explained, reflecting on why she never walked down the aisle.

Instead, Keaton turned her focus to motherhood later in life. In her 50s, she adopted her daughter Dexter and son Duke, calling the decision “the most life-changing and fulfilling thing” she had ever done. Becoming a mother, she said, gave her a sense of purpose that no romantic relationship could match.

Keaton’s life choices — from refusing to marry despite societal expectations to adopting children on her own — made her an enduring symbol of individuality and empowerment. Even in death, her legacy as a trailblazer in both Hollywood and life continues to inspire.

Diane Keaton’s dating history is more than a list of famous names — it’s a testament to her refusal to conform, her belief in love on her own terms, and her enduring legacy as one of Hollywood’s most original stars.
