A second mistress has just come forward claiming she had an affair with Khloe Kardashian's husband Lamar Odom, earlier in the summer. According to Radar Online, Polina Polonsky spilled details of the affair to Star magazine.

She alleges that she met the athlete at the beginning of June at Roosevelt Hotel in Los Angeles, where he has reportedly been living since Kardashian kicked him out the house.

"I was under the impression that he had left Khloe, and that's why he was living at the Roosevelt," she told Star. "He acted completely available and we definitely had a mutual attraction."

She claims the two were definitely flirting with each other and it quickly escalated during the time she continued to meet him at the hotel. A couple weeks after they first met Polonsky claims they shared their first kiss and soon were doing a lot more than that. She told the magazine they had sex for the first time back at her apartment.

"After we had sex, Lamar stayed the night with me," Polonsky told Star. "The next day we went back to the Roosevelt. I stayed there with him for the next couple of nights."

She also revealed to the tabloid that the "Keeping Up With the Kardashians" star and her mom Kris Jenner caught on to the affair and showed up at hotel to confront Odom and Polonsky. She claims Odom told her that his wife and mother-in-law were banging on the wrong door at the hotel and when no one answered Kardashian busted the door in.

The mistress went on to say that Odom was so embarrassed about what happened at the Roosevelt that he left and stayed a couple weeks at Polonsky's apartment. The mother-daughter duo allegedly found out where she lived and came by her apartment.

"I couldn't believe they found where I lived and came to my apartment!" she told Radar. "They were knocking on the door, but Lamar refused to answer."

The reality star and her husband faced cheating allegations before when Radar again broke the news that Odom was allegedly having an affair with 29-year-old Jennifer Robinson.
