Khloe Kardashian's marriage rocked by new infidelity claims as lawyer alleges she had 'six-week summer affair' with Lamar Odom

They were just rebuilding their marriage following claims that he had been unfaithful with stripper Jennifer Richardson.

And now Lamar Odom has been hit with fresh infidelity claims, as RadarOnline.com claim to have proof that the professional basketball player cheated on wife Khloe Kardashian with lawyer Polina Polonsky.

The website also claims that Polina passed a lie detector (polygraph) test to prove she is telling the truth.

New claims: Lamar Odom has been accused of cheating on Khloe Kardashian with lawyer Polina Polonsky

According to America's Star magazine, Lamar and Polina first met at Los Angeles' Roosevelt Hotel on June 2nd, where the sportsman had been staying for a week amid marital difficulties with Khloe.

Polina said: 'I was under the impression that he had left Khloe, and that’s why he was living at the Roosevelt. He acted completely available and we definitely had a mutual attraction.'

Brunette Polina, who claims to have had a six-week long affair with Lamar, claims she had her first kiss with him on June 9th, before consummating their romance on June 13th at her apartment.

She 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.'

However, Polina said Khloe was quick to discover her husband's infidelity.

In an attempt to confront Lamar while he was in the midst of being unfaithful, Polina claims Khloe and her mother Kris Jenner made an impromptu visit to The Roosevelt Hotel.

Getting no answer after knocking on what they believed to be Lamar's door, Khloe allegedly kicked down the door, before realising she had the wrong room.

Khloe and Kris then found the right room and reportedly confronted Lamar, who was on his own as Polina was at her apartment at the time.

Polina then claims that Lamar was so infuriated by his wife's behaviour that, on June 22nd, he temporarily moved into her apartment, where he stayed until July 8th.

However, Khloe is said to have then found out where Polina lived, enlisting the help of momager Kris once again to confront her spouse.

But Polina said: 'I couldn’t believe they found where I lived and came to my apartment! They were knocking on the door, but Lamar refused to answer.'

This is not the first time that Lamar has been accused of cheating on Khloe.

It was previously claimed that Lamar has been cheating on Khloe with 29-year-old brunette, Jennifer Richardson, after meeting in a Washington, D.C strip club a year ago.

Although it was initially claimed that Khloe had kicked the NBA star out of their home, a source close to the reality star later told MailOnline: 'They're more in love than ever. Khloe did not kick Lamar out of the house, they are 100 per cent fine.'

MailOnline has contacted representatives for Khloe and Lamar for comment on the latest claims.
