Who Is Polina Polonsky? Second Lamar Odom Mistress Steps Forward, Says He Cheated On Wife Khloe Karashian

NBA star Lamar Odom is in the hot seat again this week after a second woman has stepped forward to claim they had an affair. The allegations come just weeks after the Los Angeles Clippers player denied he had stepped out on his reality star wife Khloe Kardashian with another woman.

Odom, 33, has been secretly shacking up with a Sherman Oaks, Calif., attorney name Polina Polonsky, Radar Online reports. This is the second time in recent months the NBA player has been accused of having an affair. In July, Jennifer Richardson, 29, stepped forward and claimed she had an affair with Odom, who called her an “NBA groupie,” Radar Online said.

Polonsky claims that she had a six-week affair with the athlete and even passed a polygraph test to back her claims. Polonsky, who first met Odom in June 2 at the Roosevelt Hotel in Los Angeles, claims she believed the Clippers player was single after Odom claimed that he was residing at the hotel. “I was under the impression that he had left Khloe and that’s why he was living at the Roosevelt,” she said. “He acted completely available and we definitely had mutual attraction.”

Polonsky said that their relationship heated up on June 9 when they shared their first kiss. Days later, they consummated their relationship at her apartment, she claims. “After we had sex, Lamar stayed the night with me,” she said, adding that she also stayed overnight in his Roosevelt hotel room on multiple occasions.

Although Odom's wife has previously denied reports her husband has been unfaithful, Polonsky claims that both the 29-year-old reality star and her mother, Kris Jenner, were fully in the know. The report also claims that the duo visited Odom's mistresses' apartment to confront her. “I couldn’t believe they found out where I lived and came to my apartment,” Polonsky said.

Odom has faced a couple of rough seasons since leaving the Los Angeles Lakers following the 2010-11 season, and the power forward is now a free agent.
