The 55-year-old businesswoman, who divorced Kim's father Robert Kardashian in 1990, doesn't think that the 30-year-old will split from Kris Humphries following their wedding this Saturday.
Jenner told the Kyle and Jackie O radio show: "I've been through that. I've had a divorce, and we remained really, really good friends until he passed away.
"But you know what, I think she's found her guy. She is just so happy. He's very tall. He is like, so tall, he should probably play basketball. Oh wait, he does!"
Jenner, who has five other children, explained that she loves watching her kids grow up.
She added: "She is really excited and it's true, you think about this day your entire life. As soon as I had kids, you start thinking about all the milestones that you're going to come across, you know, through their childhood, and then when they get married it all comes flashing back at you in about five minutes. You're like 'What just happened!?'"
Kim and Humphries attended their wedding rehearsal dinner with friends and family last night.
