Kyle Rittenhouse says he's no longer a fan of LeBron James ... saying the Lakers star's shade toward him during his trial "really" ticked him off.
"I liked LeBron," the Kenosha shooter said Monday on The BlazeTV's "You Are Here" show. "And, then I'm like, 'You know what, f*** you, LeBron.'"
If you missed it ... LBJ mocked Rittenhouse after the 18-year-old gave an emotional testimony on the stand during his homicide trial last month.
Rittenhouse fought back tears while explaining how the Aug. 25, 2020 shootings in Wisconsin unfolded ... and then he got so choked up, the judge actually paused the court proceedings for several minutes.
LeBron, though, didn't believe Rittenhouse was actually remorseful or even crying at all ... writing in a social media post, "What tears????? I didn't see one."
What tears????? I didn’t see one. Man knock it off! That boy ate some lemon heads before walking into court. 🤣🤣🤣 https://t.co/LKwYssIUmD
"Man knock it off!" James continued. "That boy ate some lemon heads before walking into court."
LeBron added several crying emojis to the post as well.
When Rittenhouse finally spoke publicly about James' comments -- he made it clear, he now despises the NBA superstar over it all.
"I was a Lakers fan too before he said that," Rittenhouse said. "I was really pissed off that he said that."
As we previously reported, Rittenhouse was found not guilty on all charges in his Kenosha shooting case ... and he's been spotted gleefully in public ever since -- while also earning praise from former President Donald Trump, who called the teenager "a nice young man."
