Amid mounting speculation that the couple were preparing to call time on their four-year marriage - some media outlets were reporting that divorce documents were being filed this week - Kris spoke to TMZ to categorically deny the claims.
"Khloé and Lamar are absolutely not getting divorced," the Kardashian matriarch stated. "There's been no talk of divorce."
She went on to say that both Khloé and Lamar were at her house two days ago, and everything was fine.
Other sources close to the couple, who got married one month after they started dating, have insisted they are not going to split, with one insider confirming that Khloé, 29, has not even spoken to a divorce lawyer.
It comes amid reports that Lamar, 33, allegedly had a year-long tryst with Jennifer Richardson, which ended in March 2013. Since then, another woman, lawyer Polina Polonsky has also claimed she had a six-week affair with the basketball star.
So far Khloé has remained silent regarding the claims. She has not been seen in public with her husband since 2 June, and Lamar was not present at a family dinner at the weekend to celebrate her half-sister Kylie Jenner's 16th birthday.
