After James demanded the Cleveland Cavaliers acquire another playmaker, Chuck called the four-time MVP "whiny."
James came over the top with his response, going personal: LeBron brought up Charles' past legal troubles and the time he spat on a child.
On Thursday night, Barkley tried to squash the beef on air. Shaquille O'Neal came to James' defense, saying he would have reacted similarly.
"LeBron is one of the 10 greatest players I’ve ever seen," Barkley said. "He’s an amazing man. What him and his guys have done business wise is amazing. But my comments were what I said, I stick by them, but I’m never going to say something personal about another NBA player.”
But two nights prior, Chuck delivered a slightly different message: F**k the haters.
That was from the DJ booth at the Koo Koo Room in Atlanta.
"This is for all you f**king haters out there," Barkley said while cueing up "Hate Me Now" by Nas. "For all you f**king haters, F**k y'all!"
Was this a massive subtweet to Bron? Probably not, because there's no way Barkley knows what "subtweet" means and it appears he didn't know he was being filmed.
Still, Chuck provided those in attendance with a very interesting tidbit about the Hall of Famer's morning routine: "I listen to this song every day I wake up."
Barkley's love of partying was part of LeBron's diatribe against the analyst.
"I never had unpaid debt in Las Vegas," James said on Monday night. "I never said, ‘I’m not a role model.’ I never showed up to All-Star Weekend on Sunday because I was in Vegas all weekend partying."
