Kris, 57, who married the former athlete in 1991 and gave birth to two daughters Kendall and Kylie with him, is also said to be living separately, reported Radar Online.
"They've had problems for a long time and have been separated for months. They pretty much just have a business elationship at this point. Their marriage is over," a source said.
It is rumoured that Kris's urge for fame brought distance in her relationship. The talk show host has four children - Kourtney, Kim, Khloe and son Rob - from her first husband Robert Kardashian.
