West had secretly whisked the reality star to meet his beloved granddad to pave the way for the couple to wed after her divorce.
Portwood, 97, was left stunned when his grandson turned up with his girlfriend at his humble home in Oklahoma City.
He said that he has never met anyone who was married as long as him.
“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,” the Sun quoted him as saying.
He said that all of his daughters didn’t make it, which included West’s mother and father.
