9:10 AM -- Lil Wayne joined FS1's "Undisputed" with Skip Bayless on Friday to address his beef with the team ... chalking it all up to an issue with security.

"They was just doing their job," the rap icon said ... explaining as he was attempting to make his way to his courtside seat, a staffer stopped his crew in their tracks and told them to enter from another part of the arena.

But when they got to the second entrance, Weezy noticed they would have had to ask other spectators to get up from their spots to allow his group through to their seats ... and he didn't want to bother them, so he walked back to the original entry.

When he got back there, Wayne said the same staffer got upset ... saying, "I told you guys to go to the other entrance!" -- which he felt was a bit out of line.

Wayne also said he was told after the fact that the issue was that he'd have to wait for a dead ball to get to his seat -- but that wasn't relayed to him.

Tunechi -- who admitted he was only at the game as part of a brand deal -- said the experience left a bad taste in his mouth ... and he'll only go back to Crypto because his son is a diehard Laker fan.

Lil Wayne says he was "treated like s***" at the Lakers game on Thursday night ... and he's so pissed over what went down, it seems he's ready to cut ties with his beloved squad.

It's not quite clear exactly what happened with Weezy as he made his way to Crypto.Com Arena to watch LA battle with the Washington Wizards ... but just 90-or-so minutes after the game tipped off, he took to X to criticize the Purple and Gold.

"Wow!" he wrote. "Got treated like s*** at the Laker game just now."

Wayne didn't get into specifics ... but he suspected it all had to do with some previous comments he's made about one of the team's superstars, Anthony Davis.

If you're unfamiliar ... Wayne, who's always spotted in courtside seats at Lakers games, makes regular appearances on Fox Sports 1's "Undisputed," and when the topic turns to LA hoops, he's often critical of Davis. In fact, during a November episode, he said the team should straight up trade the nine-time All-Star.

In his post on X, Wayne wrote, "I figured they’d do me that sooner or later" "bc of what i said abt AD," but he added that he's gotten an uneasy feeling from the team for a while now -- which apparently has him questioning his fandom going forward.

"All good I get it," he said. "F*** em. It isn’t what it isn’t. I’m used to it."

Neither he nor the Lakers addressed the matter further as of Friday morning.

It seems a bunch of other celebs, though, had no issues attending the game ... Flea, Kayvon Thibodeaux, Corey Gamble, Jay Mohr and even Chevy Chase were all spotted near courtside with grins on their faces.

Everyone there got to enjoy quite the game too -- as LeBron James and Davis combined to score 71 points in a 134-131 overtime win.
