Little to his knowledge, he's also entangled in a fierce feud with Jimmy Kimmel Live sidekick Guillermo.
The Finals mainstay has not talked to the comedian, who grew weary of receiving the cold shoulder. Rather than trying to pester James during this year's NBA Media Day, Guillermo turned the tables by refusing to talk to the Cavaliers superstar.
Instead, he asked members of both teams to inform James of his rejection. For some reason, Draymond Green and Kevin Durant were especially uninterested in passing along the message.
He eventually broke his promise by yelling "I'm not talking to you" at James, who either didn't hear or care about a late-night comedy segment while preparing for his seventh straight championship series.
