Unbelievable... Kris Jenner was Screwing Khloe's husband Lamar Odom behind her back

Here is a report, from Today's STAR MAGAZINE. They claim to have pics to substantiate their report:

The alleged incident is said to have taken place in the Spring of 2014, a few months after Khloe, 30, had filed for divorce against Lamar.

He was in a "dark place" at the time, after being publicly shamed for cheating on Khloe and for secretly doing drugs, including crack, which led to the demise of his basketball career.

"Kris knew how to get in touch with Mara - and how to do it without Khloe knowing. She had been reaching out to him to lend her support for a long time." the source says. "Lamar never responded to her, until out of the blue, he suddenly agreed to meet her. He was feeling alone, and she offered him a shoulder to cry on . . . [and] one thing led to another," the source claims to have heard.

It was 59 year old Kris, the insider claims, who apparently took their relationship to the next level. "She's relentless and doesn't know when to stop," says the source. Lamar, on the other hand, "realized he'd made a mistake the minute it happened." But despite Lamar's regret over the fling, he and Kris may have continued their affair for two months.
