Cleveland cares not for Celebrity Row.

An assortment of the Knicks’ most famous fans traveled to Rocket Arena for Game 4 of the Eastern Conference finals for an up-close look at a Knicks sweep on Monday.

The Cavaliers didn’t exactly roll out the red carpet, however. Self-proclaimed Knicks “superfan” and rapper Fat Joe told ESPN the team scotched the courtside tickets he bought — with the Cavs telling The Post they were enforcing rules against re-selling first-row seats.

That didn’t keep the star power too far away.

Timothee Chalamet — with girlfriend Kylie Jenner in tow — reprised his usual Madison Square Garden role, and took selfies with fans.

Fat Joe did find his way into the building, as did actor Tracy Morgan. Garden sideline staple Ben Stiller didn’t miss the action, either.

Director Spike Lee made the trip, sharing a moment with Knicks assistant Rick Brunson before tip-off.

And what would a Knicks playoff game be without the alumni? Stephon Marbury hyped up a plane full of Knicks fans en route to Cleveland while John Starks, a guard on the 1999 squad that went to the Finals, watched this team do the same. Franchise icons Patrick Ewing and Walt “Clyde” Frazier were on hand to dole out the MVP trophy to Jalen Brunson.

Not that it was a full-on takeover. A game after Travis Kelce and Taylor Swift showed out — and the Chiefs star chugged a beer —rapper Machine Gun Kelly rooted on the home team wearing a Guardians hat.
