Lamar Odom is apparently losing his cool in light of a report he's been cheating on wife Khloe Kardashian.

When asked about the accuracy of a recent Star magazine report claiming Odom has been unfaithful to the Keeping Up with the Kardashians star for months, the NBA basketball player flipped out on a paparazzo on Wednesday, People reported.

Odom was reportedly approached by two photographers while stopped at a red light near his Los Angeles home, and when questioned about whether he had cheated on Kardashian, he angrily shot down the rumors.

An eyewitness of the exchange told People that Odom lost control.

"Lamar got furious that they had the nerve to ask him and he absolutely lost it. He got out of his car and went crazy on a third photographer. He reached into the photographer's car, grabbed the camera equipment and threw it into the street. Lamar was very upset and seemed beyond stressed out," explained the eyewitness.

TMZ posted a video of the incident and Odom seemed to handle things calmly -- at least at first.

"I would never cheat on my wife, that's why I wear my wedding ring," Odom quietly told one of the photographers from inside his vehicle. "Step out of the car. I want to talk to you."

Odom then apparently grabbed the photographer's equipment and put it all in the trunk of his car. However, after arguing with the man, Odom eventually gave everything back by placing the items in the street and then taking off.

In the middle of the confrontation, Odom was shown posing with a fan for a photo with a big smile on his face. Kardashian stood by her man's behavior on Twitter.

"Hehehe I just love my hubby :) love when your in rant mode!" the former The X Factor host tweeted on Wednesday.

A source close to the Kardashian clan told People, "The paparazzi has been continuously taunting the family. Enough is enough!"

The report "couldn't be farther from the truth," added another source.
