Actor Michael Rapaport claimed Cleveland Cavaliers star LeBron James once disrespected his children during a previous interaction with the basketball star.

During a nearly 40-minute interview with New York City-based radio station Power 105.1’s "The Breakfast Club" on Tuesday, Rapaport shared an anecdote involving the three-time NBA champ and the actor's two sons. He claimed that James failed to acknowledge the actor’s children when they met years ago. 

"When they ran into LeBron, he dissed my kids," Rapaport told the show. "He gave 'em the f—kin' Heisman and turned his back to them."

Rapaport suggested that the incident happened because a friend of his friend apparently slept with James’ friend, which may have caused some tension. His kids should have been left out of the situation, Rapaport said.

"It has nothing to do with a 10 and an 8-year-old, don't play me and my kids," the veteran actor said.

He added: "Out of all the athletes, out of all the celebrities, out of all the rappers I've ever met — especially with my kids — that was the only motherf—ker that ever did that. And I was like, 'Hell f —kin' no.'"

Rapaport, 47, who appeared on the radio show to promote his new book, "This Book Has Balls: Sports Rants from the MVP of Talking Trash," is known for voicing his opinion.

After the abrupt cancellation of ESPN’s talk show "Barstool Van Talk," the New York City native took to Twitter on Monday and lamented that the sports network pulled the show after one episode to "send a message."

"ESPN canceled @barstoolsports Van Talk to send a message of some sort have Dick Swinging Power.@SarahSpain & them are self-righteous chumps," Rapaport wrote.

Rapaport has appeared in movies such as and Higher Learning (1995) and Deep Blue Sea (1997), according to his IMDb page. He currently hosts the "I Am Rapaport Stereo Podcast" on the CBS Local radio network with childhood friend Gerald Moody.
