Al Pacino is mourning more than just a Hollywood legend — he’s mourning the woman he never stopped loving.
After Diane Keaton’s death at 79, the 85-year-old actor reportedly confessed deep regret over never marrying her. “Looking back, Al admits the love of his life was Diane,” a close friend revealed. Despite fame and countless romances, his heart always belonged to her.

Their love story began on the set of The Godfather and burned bright with passion, humor, and heartbreak. But when Keaton asked him to commit, Pacino couldn’t — a choice he now calls his biggest mistake. “He’ll forever regret not making his move when he had the chance,” the source added.
At a 2017 tribute, Pacino said softly, “I love you, forever.” It was both a farewell and an apology. Keaton once wrote, “I wanted him to want me as much as I wanted him.” Today, that wish echoes through Hollywood’s grief.
Some love stories don’t end — they simply pause forever. And for Al Pacino, Diane Keaton will always be the one that got away.
