Sydney Sweeney showed up to Game 5 of the 2026 NBA Finals on Saturday night wearing a Jalen Brunson jersey — and her timeline did the rest. By the time the Knicks finished their evening in San Antonio, the Euphoria star was the lead character in the night’s other competition: the running internet debate over how many A-list celebrities have suddenly become lifelong Knicks fans this June.
Sweeney arrived at the Frost Bank Center in San Antonio before tip-off in a white shirt reading “New York 11” — Brunson’s number. Heavy, which posted the first clear courtside video, framed her as one of the few neutral-territory celebrities to make the trip down for a Game 5 the Knicks needed to close out the championship on the road. Other reports through the night confirmed she was in a custom Brunson jersey under a navy blazer.
The mockery started inside the first quarter. “Why is every celebrity a Knicks fan all of a sudden?” one fan posted, in what became the most-shared version of the complaint by halftime. Another stitched together a clip of Sweeney in the Brunson jersey next to her own Spokane-area upbringing, captioned “Isn’t Sydney Sweeney from Washington lol?” Sweeney is, in fact, from Spokane, Washington; she has spent significant time in New York in the last two years, including filming Euphoria’s third season largely in the city.
It was not Sweeney’s first Knicks Finals appearance. According to Yahoo Sports’s accounting of Madison Square Garden’s Game 4 seating chart, she had attended that game in New York but was placed three rows back — not in the first-row block that ran from Taylor Swift to Jerry Seinfeld to Timothée Chalamet, where individual tickets reportedly cleared $100,000. By Sunday morning, that snub was being recast as foreshadowing.
The wider Knicks-celebrity question now driving the discourse is genuinely strange. New York has not been to the NBA Finals since 1999. The 2026 Garden has hosted, in a single playoff run, Taylor Swift in a custom “Stevie Knicks” shirt, Timothée Chalamet and Kylie Jenner in matching Chrome Hearts denim, Jerry Seinfeld, Spike Lee, Tracy Morgan, Ben Stiller and — in one viral Mariska Hargitay moment — a Law & Order star jogging ten blocks from a Broadway curtain call to catch the fourth quarter. The Sweeney Game 5 frame fits the broader pattern almost too cleanly.
Sweeney’s representatives have not commented. The actor has said in past interviews she is a casual basketball fan and grew up around the Seattle SuperSonics before the franchise’s 2008 relocation — a detail her defenders dug up on Sunday morning to argue the bandwagon framing was unfair. Detractors pointed out that the SuperSonics last played a home game when Sweeney was ten.
The professional context is also moving. Sweeney is currently mid-press cycle for Euphoria’s final season, which premieres on HBO later this summer. Her last round of Vanity Fair coverage focused on a cut pole-dancing sequence she has asked HBO to release as bonus footage. The Brunson jersey, in that wider campaign, reads less like fandom and more like a fashion-meets-press-tour move — the kind of courtside placement Hollywood publicists have spent two months engineering at the Garden.
According to Heavy’s late-night recap, the Sweeney clip was the most-shared celebrity moment of Game 5 across X, TikTok and Instagram by the early-Sunday cutoff, outperforming the Spurs comeback that briefly threatened to push the series to six. Whether that ratio represents anything about the NBA Finals itself or just about how thoroughly the Knicks run has been absorbed into the celebrity-content economy is, at this point, mostly a matter of which timeline you scrolled first.
The actor herself, for what it is worth, looked unbothered. Cameras caught her cheering on Brunson at the end of the third quarter. The Knicks closed the road game out. By 1 a.m. Eastern, the “isn’t she from Washington” jokes had settled into the same place every other 2026 Knicks-celebrity bit eventually settles — a flood of replies, a couple of late-night-host writers already sketching the Monday cold open, and a sense that the next high-profile name is one tip-off away.
