Khloe Kardashian Odom has been denying for months that her marriage is in trouble, but a woman who claims she had an affair with Lamar as recently as June says he acted completely available and made it clear that he didn’t want to be with Khloe anymore.

“I was under the impression that he had left Khloe … he acted completely available and we definitely had a mutual attraction,” Polina Polonsy said. “After we had sex, Lamar stayed the night with me; the next day we went back to the Roosevelt. I stayed there with him for the next couple of nights.”

Polonsky says that Khloe discovered the two of them together in another hotel room in July and confronted her, causing such a scene that Polonsky wanted to call the police.

“I told her to leave, but she refused. I called the front desk and asked them to call the police because I was so scared, but no one ever came,” she said. “While Khloe was screaming outside the door, Lamar was calling people to come and get her. She was out of control. The whole scene was so frightening — and I couldn’t understand why we were hiding, because he made it clear that he didn’t want to be with her!”

Now, the young lawyer has reportedly passed a lie detector test about the affair and says she wants everyone to know what she’s been put through because she fears for her safety.

“She’s investigated my loved ones, and she personally tried to attack me,” Polina said. “I can’t even go home, because I’m scared that something bad will happen. I want my story to be made public.”

Khloe, meanwhile, is reportedly still trying to make things work with Lamar.

“Khloé has been fiercely loyal to Lamar – she’s always been a devoted wife,” a source told British magazine Heat. “But she and Lamar have suffered after trying for a baby for so long with no joy, it put pressure on their relationship. Now they’re so distant, no one knows if they can repair things.”
