Lamar Odom was rejected at a West Hollywood nightclub on Tuesday, May 13 by French Montana's security team. According to reports, Odom showed up to Penthouse nightclub but was told at the door that he couldn't come inside and had to leave.

French was a special guest that night at the club. Sources told E! News that the rapper told the club's owner that Odom was not to come inside since Khloe Kardashian would be there. Kardashian and Odom split in December after four years of marriage.

According to E!, the reality star and French were sitting in a car outside the club when the incident happened.

"It was Khloe, French, Kim [Kardashian] and Jonathan Cheban. Kim and Jonathan exited the car and were filming a scene for the show while Khloe and French were in the car talking. Just then, Lamar walks past the car and heads around to the front of the club to go in," a source told E!.

"Lamar was rejected at the door and was forced to leave," the source added. "He was later seen walking by Khloe and French as they sat inside her Range Rover."

The source said Kardashian was shocked to see her ex at the club and was not expecting him to be there.

"The doorway to the club was surrounded by French's security, who made it clear to Lamar he would not be allowed in," the source said. "As he was leaving, he walked again past the car that French and Khloe were in and made his way off the property."

After Odom left, Kardashian and her friends went inside.

"It seemed obvious Lamar was there looking for Khloe," the source told E!. "This was not a random coincidence. He seemed desperate."

According to TMZ, Odom did not cause a scene even when a photographer mentioned the rapper's name to him. Instead the athlete and his crew went to Lure nightclub, a few miles away.
