A second woman has come forward claiming she had an affair with Lamar Odom.

Polina Polonsky alleges she had a six-week relationship with the basketball player - who is married to Khloe Kardashian-Odom - earlier this summer and according to RadarOnline.com, she has passed a lie detector over her allegations.

She told Star magazine: ''I was under the impression that he had left Khloe, and that's why he was living at the Roosevelt [Hotel in Los Angeles].

''He acted completely available and we definitely had a mutual attraction.''

Polina, a lawyer, claims the basketball star had been living at the upmarket accommodation for over a week until he went back to her home and engaged in sexual activity with her and that she later went back to his plush hotel to meet him again.

She explained: ''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.''

Khloe and her mother Kris Jenner allegedly stormed over to the hotel to confront her beau and his secret lover, but according to Polina, Khloe turned up at the wrong door and smashed her fist through it.

This isn't the only time the LA Clippers player has faced allegations of cheating, as Jennifer Richardson previously claimed Lamar had a year-long affair with her, beginning in January 2012, before she broke it off in March this year.
