There may be trouble brewing in the marriage of Khloe Kardashian and Lamar Odom as the NBA baller has been spotted out with several different woman over the past few weeks. And it's not the fertility issues this time.  Get the deets inside....

The marriage of LA Clippers star Lamar Odom and "X Factor" host Khloe Kardashian may be on the rocks as In Touch reports three sightings of the baller with other women (while traveling with the team on road trips and in LA).  

First off, Teresa Witt, a partier at club Skkybar in Oklahoma City, says she saw Lamar with two brunettes on Nov. 20.

She said, “He went out the back door, and it looked like he was about to leave. 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?’” Messy.

But that was just the beginning as one source close to the couple said he snuck two different women up to his Trump SoHo hotel room during Thanksgiving with the help of his driver.  Khloe decided to stay in L.A. with her fam while Lamar was in NYC for a game.

Then, folks in LA at Greystone Manor saw him with “a short blond girl” on Dec.9. The witness said they were, “...talking so close it looked like they were kissing. He seemed to be having the time of his life.”

These alleged sightings haven't seem to put a damper on Khloe's spirits though, even though she was spotted wearing a sweatshirt from Lamar's Rich Soil clothing line last week.  Or....maybe she didn't know about this week's edition of In Touch?
