Timmy gone wild.
Timothée Chalamet celebrated in a big way after the New York Knicks narrowly beat the San Antonio Spurs 107-106 in Game 4 of the 2026 NBA Finals on Wednesday.
In a social video shared by “Entertainment Tonight,” the actor could be seen grabbing a reporter’s microphone and shouting alongside other thrilled Knicks fans inside Madison Square Garden.
At one point, Ben Stiller joined Chalamet, 30, as they jumped up and down with the fans.
During the madness, Kylie Jenner filmed her boyfriend’s wild celebration on her phone with a big smile on her face.
“Let’s f—ing go!” Chalamet yelled into the mic, before admitting, “I don’t even know what camera’s going.”
The “Marty Supreme” star then gave a shoutout to Knicks player OG Anunoby, who scored the game-winning basket with a second left on the clock.
“Kylie doing the proud girlfriend thing,” one fan wrote in the comments section of ET’s Instagram clip.
Another fan wrote of Chalamet, “He’s been a fan since he was a kid, love this for him.”
“Ben stiller jumping up and down is so cute,” a third comment read.
In another viral post-game video, Chalamet went shirtless as he continued to celebrate with a mob of Knicks fans.
He ripped off his Chrome Hearts oversized denim jacket with bright orange crosses and white T-shirt, while his blue jeans began falling off and exposed his black underwear, as he went wild in the crowd.
The shirtless star then ran away as Jenner — who similarly recorded the chaos — laughed and followed him.
Chalamet and Jenner, 28, matched in custom Knicks-themed Chrome Hearts-embroidered denim jackets and jeans at Wednesday’s game.
After the Knicks won, Jenner shared a sweet embrace on the court with Taylor Swift, who previously feuded with the makeup mogul’s sister Kim Kardashian.
Other A-listers who were at the game included Spike Lee, Mariska Hargitay, Alana and Este Haim, Scooter Braun and Sydney Sweeney.
Chalamet is a longtime Knicks fan and even opted out of attending the 2026 Met Gala with Jenner to watch the team play against the Philadelphia 76ers last month.
The actor and the Khy founder, however, have turned several Knicks games into date nights and shared a sweet kiss during the second game of the NBA Eastern Conference Semifinals Playoffs on May 6.
At the time, they appeared head over heels for each other, as the “Dune” star pulled the businesswoman in from around her waist.
The duo also decked themselves out in Knicks merch at Game 4 of the Eastern Conference Finals later that month.
Chalamet has been front and center to support the Knicks since Game 1 at San Antonio’s Frost Bank Center on June 3.
He arrived at the venue in style, wearing an orange and blue Adidas soccer jersey and a custom “Marty Supreme” diamond pendant in honor of the 2025 Josh Safdie-directed film.
The “Little Woman” star attended Game 2 at the Texas venue alongside Ben Stiller, Fat Joe, Billy Baldwin, Allan Houston and Walt “Clyde” Frazier.
Chalamet channeled “Despicable Me” villain Vector Perkins when he arrived at Game 3 wearing an orange tracksuit to MSG.
The “Call Me By Your Name” star was seen standing and shouting in distress as the Knicks lost to the Spurs 115-111.
Jenner has cheekily played into Chalamet’s obsession with the sports team, including when she reposted a TikTok of “Sex and the City” character Samantha Jones saying, “I don’t get laid unless the Knicks win.”
Additionally, in previous years, eagle-eyed fans have spotted Knicks-colored lingerie in the makeup mogul’s suitcase.
Jenner and Chalamet started secretly dating in 2023 and have since flaunted their romance on red carpets and date nights.
