West recently took the reality star to meet his grandfather and though Portwood liked Kardashian, he believes that nobody today works hard enough to make a marriage work, reported Sun Online.
Portwood, 97, was left stunned when his grandson turned up with his girlfriend at his home in Oklahoma City.
"I don't do weddings. I don't like weddings. I've never seen one make it. You spend a lot of money, then in weeks you're separated," he said.
About Kardashian he said, "She's beautiful and just as sweet as she is beautiful - and that's what I like. She was down to earth, she's rich and those kind of people have got everything.
