Diane Keaton was never married. Throughout her life, she had notable high- profile relationships, including romances with Woody Allen, Al Pacino, and Warren Beatty, but she chose not to marry. She openly expressed that she was glad she never married, feeling that it wouldn't have been a good idea for her, a stance she maintained from her teenage years. Despite never marrying, she adopted two children, a daughter Dexter and a son Duke, in her 50s and embraced motherhood independently. Keaton's decision reflected her desire for independence and a different kind of life than traditional marriage offered.
