LeBron James is not a fan of the Kardashian family. The 32-year-old Cleveland Cavaliers star allegedly is "not cool" with his teammate, Tristan Thompson, dating Khloe Kardashian as he's furious that the crew of the Kardashian family show, "Keeping Up with the Kardashians", recently crashed the team's workout.

Speaking to HollywoodLife.com, an NBA insider revealed that "LeBron was pissed about outsiders coming into his work home and sticking a camera into his face -- that's so not cool." According to the insider, "Apparently the camera crew had permission to film, but not from him or the rest of the team."

"All of the Cavs have been roasting Tristan about dating Khloe, pretty much from day one, but LeBron has been particularly scornful," claimed the source, adding that "he regularly 'jokes' about the Kardashian curse, and warns Tristan that his career will go the same way as [Lamar Odom] and Kris Humphries if he isn't careful."

Khloe's boyfriend, with whom she is reportedly having her first child, is reportedly trying to deal with the torment as best he can. "Tristan just brushes it off though, and ignores the teasing," claimed the source. "He loves Khloe and knows that she's so much more than just reality TV fodder. But LeBron thinks he's crazy getting involved in that family, and he doesn't want to be involved in all their drama, especially when it encroaches on his work time."

LeBron was said to show up at his team's workout session on October 3 only to find the place filled with cameras allegedly shooting "KUWTK". It was also believed that they were there to film Khloe's beau Tristan, and LeBron was not having it, calling it a "s**t show" over and over again in a Snapchat video he posted.

"Tristan is embarrassed by the distraction and tension created by the 'KUWTK' camera crew. He loves Khloe and wants to make her happy, but he had no idea the cameras would cause so much attention and create drama within his team," a source close to the 26-year-old athlete previously told HollywoodLife.com.

Part of Tristan loves being in the spotlight, but he promised LeBron and the team that Khloe and her reality show would not be a distraction," the insider continued, adding, "Now that the camera crews have bombed with his team, Tristan fears he may have to decide what is more important. He can't keep both his teammates and his girlfriend Khloe happy. Tristan feels he is in a lose-lose situation."
