The American-French actor and the businesswoman attended the Knicks' playoff game against the Philadelphia 76ers.
Kylie Jenner and Timothée Chalamet are totally in sync.
On Wednesday, May 6, the 28-year-old reality star and the Marty Supreme actor, 30, were photographed wearing matching outfits as they had a date night at Madison Square Garden for the second game of the NBA Eastern Conference Semifinals Playoffs between the New York Knicks and the Philadelphia 76ers.
The couple, who were first linked in April 2023 and have been going strong ever since, sat courtside in coordinating denim jeans.
They also each paired their casual looks with an orange jacket, paying homage to the New York native's home team.
Video obtained by PEOPLE showed Chalamet resting his hand on the small of Jenner's back as the pair walked to their seats, greeting those around them on the way.
Just two days ago, the Complete Unknown actor skipped the 2026 Met Gala and watched the Knicks instead while the Kylie Cosmetics CEO attended the annual fundraising benefit for the Metropolitan Museum of Art and wore a custom Schiaparelli look on the red carpet, which featured a nude corset with faux nipples underneath a voluminous skirt.
Chalamet and Jenner have attended multiple Knicks games together, including when the Knicks took on the Indiana Pacers for a pivotal playoff game in May 2025 in coordinating clothing.
At the time, Jenner wore a leather orange jacket with a white neckline and zippers. She kept the garment open and showed off her crop top. The reality TV star finished the look with a pair of black leather pants. After sitting down in her courtside seat, she removed the jacket.
Meanwhile, Chalamet wore a bomber-style orange and blue jacket. He paired the jacket with black tank top, dark jeans and silver chain.
That same month, Kendall Jenner joined her sister and the Dune: Part Three star to watch the Knicks beat the Boston Celtics 121-113 in Game 4 of the 2025 NBA East Semifinals at Madison Square Garden.
More recently, Kylie and Chalamet sat courtside among Ben Stiller, Tina Fey and Tracy Morgan as the Knicks took on the Atlanta Hawks in their NBA Eastern Conference first-round series on April 28.
The couple made their public debut during Beyoncé's Renaissance World Tour in early September 2023. They were also seen at the 2023 US Open and the 2024 Golden Globes before making their red carpet debut at the 70th David Di Donatello Awards in May 2025.
"He's close with her family and she's close with his family," a source told PEOPLE in October 2024. "It's very serious, but also a fun relationship."
"They've really been able to figure out a good balance between working and spending quality time together," the insider added.
