Kourtney Kardashian may have been just 11 years old when her parents, Kris Jenner and the late Robert Kardashian, Sr., divorced, but now, 22 years later, their split still hurts.

Speaking to Oprah Winfrey during a Sunday interview on Oprah's Next Chapter, Kardashian, 32, admitted that seeing her mother's bond with her father break leaves her hesitant to marry her boyfriend of five years, Scott Disick, 27.

"I'm kind of scared of marriage because of that," she told Winfrey, 51, who has been in a relationship with Stedman Graham for 26 years and also is not married.

Pregnant Kardashian -- who will give Mason, 2, a sister when she welcomes a baby girl this summer -- says she may change her mind and wed Disick someday, for her children's sake. "I'd like to someday [marry] for my children, but I know that I'm just as committed as if I was married or not married," the Keeping Up With the Kardashians star admits.

Jenner's failed marriage to the late O.J. Simpson lawyer -- which disintegrated when she was caught with boy toy Todd Waterman -- is not the family's only disappointing union. (Robert Kardashian, Sr., died in September 2003, two months after being diagnosed with esophageal cancer.)

Kourtney's sister, Kim, 31, filed for divorce from NBA star Kris Humphries on Halloween in 2011.

"I've obviously made plenty of mistakes in my lifetime, but I'm not the type to sit and beat myself up over it," Kim (currently dating Kanye West) told Winfrey the family's joint interview. "If a real lesson was learned, I'm so okay with having experienced that."
