Khloe and Lamar's Marriage in Trouble?

According to In Touch:

While Khloé Kardashian has been hard at work co-hosting The X Factor, her husband of three years is partying nonstop — with other women.

Away for his team’s game with the Oklahoma City Thunder, Clippers forward Lamar Odom was partying well into the night at the club Skkybar on Nov. 20.

Now, an eyewitness tells In Touch that Lamar was lingering in an alley in the wee hours of the morning with two women.

“He went out the back door, and it looked like he was about to leave,” eyewitness Teresa Witt, who was partying at Skkybar that night, tells In Touch. “They were standing next to a cab. Both of the women were very thin brunettes in their late twenties, and when I saw them, I immediately wondered, ‘Why is Lamar in an alley in the middle of the night with two gorgeous girls?’”

And it wasn’t the only time in recent weeks that the basketball star, 33, has been spotted in the company of other women. During a Thanksgiving trip to NYC, a source close to the couple tells In Touch he snuck two different women up to his room at the Trump SoHo hotel, adding, “His driver helped him.”

And on Dec. 9, he was spotted at Greystone Manor in LA with “a short blond girl,” says a witness, “talking so close it looked like they were kissing. He seemed to be having the time of his life.”
