Actress Sydney Sweeney, known for her roles in “Euphoria” and “Anyone But You,” drew widespread attention and sparked a wave of social media buzz Saturday night as she attended Game 5 of the NBA Finals between the New York Knicks and San Antonio Spurs at the Frost Bank Center.
Wearing a Jalen Brunson jersey, the 28-year-old Sweeney appeared courtside alongside her boyfriend, music executive Scooter Braun, as the Knicks pushed to close out the series and end a 53-year championship drought. Her presence, captured in broadcasts and fan videos, quickly went viral on X, formerly Twitter, with users praising her support for the Knicks while others questioned the timing of her fandom.

Sweeney and Braun had also been spotted at Game 4, but their Game 5 appearance in San Antonio amplified the celebrity spotlight on the matchup. Broadcaster Charles Barkley notably reacted on air with visible excitement, exclaiming something to the effect of “Sydney Sweeney is here? Everybody is a New York Knicks fan now!” according to circulating clips and posts.
On X, reactions poured in rapidly, blending admiration, humor and skepticism:
- One user posted video of Sweeney in the stands with the caption, “Here we go with Knicks fan Sydney Sweeney in San Antonio with a chance to see New York win a title 🤩.”
- Another highlighted her support: “Sydney Sweeney at the Knicks Game in San Antonio. She is a big fan of the team. Do you think her presence will help them win?” accompanied by footage.
- ESPN Deportes shared a clip: “¡Sydney Sweeney en San Antonio para apoyar a sus Knicks! 🏀” (Sydney Sweeney in San Antonio to support her Knicks!).
- A popular account noted, “‘Euphoria’ star Sydney Sweeney enjoying Game 5 in San Antonio cheering for the Knicks,” with an image that garnered hundreds of likes and dozens of reposts.
Some posts took a lighter or more critical tone. One asked, “Since when is Sydney Sweeney a Knicks fan?” while another quipped that her appearance made “every celeb … a Knicks fan when the lights are on.” Comparisons to other high-profile attendees, including debates over celebrity fandom authenticity, also surfaced.
The Knicks entered Game 5 with a chance to clinch the title on the road against a resilient Spurs team led by Victor Wembanyama. Celebrity sightings have become a staple of the 2026 Finals, with stars like Timothée Chalamet, Spike Lee and others also in attendance, but Sweeney’s star power and striking Brunson jersey appeared to generate the most immediate online conversation.
Sweeney has not publicly detailed the origins of her Knicks allegiance, though her attendance at multiple games this postseason suggests genuine interest. Her appearance added Hollywood glamour to the Alamo City showdown and underscored the growing crossover between entertainment and professional basketball.
Whether her courtside support translates to on-court momentum remains to be seen, but one thing was clear on social media Saturday night: Sweeney’s presence gave fans plenty to talk about beyond the final score.
