Lamar Odom's confrontation with a photographer reportedly came after he was repeatedly quizzed about his marriage.
A report on Wednesday alleged the basketball star has been cheating on his wife Khloe Kardashian for over a year. The American edition of Star magazine claimed the sportsman has been romancing Jennifer Richardson, who is 29.
Later in the day Odom lashed out at a paparazzo while in Hollywood. Photographs and a video appear to show the 33-year-old opening the door of the man's vehicle and removing his camera. The equipment is then seen in the middle of the room while Odom is accused of smashing another car with a pipe.
According to TMZ, the incident occurred after Odom was asked about his rumoured infidelity.
"I would never cheat on my wife, that's why I wear my wedding ring," he is heard telling the paparazzo in a video, before asking the man's name and adding: "I'm gonna step out the car and I'm gonna talk to you."
