Those who regularly tune in to watch Inside the NBA on TNT know Charles Barkley doesn't hesitate ripping Russell Westbrook's bold fashion sense any chance he gets.

Well, as a guest on The Tonight Show Starring Jimmy Fallon on Thursday night, the Oklahoma City Thunder point guard and back-to-back All-Star Game MVP made it clear that he isn't fazed by Sir Charles's viewpoints about his threads at all.

In fact, when Fallon attempted to ask him about Barkley's criticism of his style, Russ told the host, "Who!?"

Oh, the disrespect is too, too real here. Check out this moment.

HA!

Barkley had this coming to him — not that the outspoken Hall of Famer actually cares — for all the times he has mocked Westbrook's style.

Chuck has also criticized Westbrook's game for shooting too much in the past without striking a balance of getting his teammates involved enough.

Westbrook's retort could make for more interesting Barkley commentary about the NBA superstar next season, which begins just over a month from now.

Can't wait ... and you already know that Russ is going to show out with his zany style.

After all, part of his appearance on The Tonight Show had him unveiling his lifestyle Jordan Brand kicks.
