Diane Keaton welcomed two children in her 50s and raised them as a single mother before her death — but never chose to marry.

“Motherhood was not an urge I couldn’t resist,” she once explained to Ladies Home Journal, per People. “It was more like a thought I’d been thinking for a very long time. So I plunged in.”

Of her decision to raise her two now grown children as a single mom, the actress told Ladies Home Journal she was “never going to be prepared to be a mother.”

As far as her relationships go, she told People in 2019 that her decision to forego marriage — despite welcoming daughter Dexter, 29, and son Duke, 25, via adoption in 1996 and 2001 — was predetermined.

“I think I’m the only one in my generation, and maybe before, who has been a single woman all her life,” she told the outlet.

The Oscar-winning actress — who dated Al Pacino, Warren Beatty, and her “Annie Hall” director Woody Allen, among others — explained that it wouldn’t “have been a good idea for me to have married.”

The “Father of the Bride” actress — who People confirmed on Saturday died in California at the age of 79 — also divulged that she’d simply never wanted to be a wife.

She was also involved with Warren Beatty.

“I remember one day in high school, this guy came up to me and said, ‘One day you’re going to make a good wife,’” she told the outlet.

“And I thought, ‘I don’t want to be a wife. No.’”

“I’m really glad I didn’t, and I’m sure they’re happy about it, too,” she said, referring to her high-profile ex partners.

Despite never marrying, some of the style icon and actress’s most memorable roles were centered around motherhood and marriage — including 1996’s “The First Wives Club” opposite Bette Midler and Goldie Hawn, and 1991’s “Father of the Bride” opposite Steve Martin.
