Nothing but net — and vintage Knicks tees — for Kylie Jenner and Timothée Chalamet.

The couple twinned in throwback gear at Game 4 of the Eastern Conference Finals on Monday, watching courtside as their team beat the Cleveland Cavaliers 130-93. The blowout completed a four-game sweep and sent the Knicks to their first NBA Finals appearance in 27 years.

Chalamet, 30, dressed for the occasion in a vintage 1999 Knicks Eastern Conference Finals Championship tee — from the last time the team made it this far — layered over a gray long-sleeve shirt.

He paired the tee with paint-splattered jeans, a black leather vintage Knicks jacket, Timberland boots and an Alex Moss diamond St. Mark necklace in white gold set with 47 carats of white diamonds.

Jenner, 28, kept her look equally game-day casual in a vintage Knicks T-shirt and blue jeans, accessorizing with a $7,300 black Chanel spring 2026 crocodile embossed shopping bag and The Row’s Sacha thong sandals.

She added some glitz with her go-to Lorraine Schwartz pear-shaped diamond studs, both worn in her left ear.

The couple drew boos from Cleveland fans when the PA announcer called out their courtside presence — unsurprising, given they were openly rooting for the visiting team on elimination night — but both laughed it off.

Chalamet and Jenner have been fixtures at Knicks games throughout the 2026 playoffs, coordinating outfits at nearly every appearance. The “Marty Supreme” actor’s devotion to the team runs deep enough that he skipped the Met Gala earlier this month to watch a first-round game instead, leaving Jenner to walk the carpet solo for the second year in a row.

Jenner has made no secret of the personal stakes involved in a Knicks win. After the team’s 2025 Eastern Conference Finals victory over the Indiana Pacers, she reposted a “Sex and the City” TikTok featuring Samantha Jones’ memorable line: “I don’t get laid unless the Knicks win.”

Jenner and Chalamet weren’t the only power couple courtside for the series. Taylor Swift and Travis Kelce attended Game 3 at Rocket Arena on Saturday, with the Chiefs tight end — a Cleveland Heights native — cheering on his hometown Cavs while Swift, a onetime Knicks fan herself, kept her allegiance under wraps.

The NBA Finals tip off June 3, with the Knicks set to face either the Oklahoma City Thunder or San Antonio Spurs.
