Stiller has become one of the more engaged celebrities among Knicks faithful in recent years, with his social media commentary during games and throughout the season serving as a connection point for the team's diehard fans.

Stiller began following the Knicks in the early 1970s and witnessed their championship runs in 1970 and 1973, attending games with his late father, Jerry Stiller, according to a 2024 ESPN story. Stiller's wall included a poster of Knicks star Willis Reed.

"The 10-year-old in me is like this is the coolest thing ever," Stiller told Stern last October.

"There's only one problem with being a Knicks fan," Morgan said during an NBA on NBC voiceover earlier this season. "I was 4 years old the last time we won a championship. A baby."

Morgan told MSG Network in 2018 he's been "watching Knick games my whole life" and he's been a passionate supporter for decades at home and away games ever since he broke through as a cast member on "Saturday Night Live."

Morgan was shown in tears on the court in Cleveland celebrating after the Knicks made the NBA Finals. He's been the public address announcer for the Knicks starting lineups at Madison Square Garden and served as the voice of the MTA's Subway announcements ahead of the NBA Finals.

"Tracy's kind of like the mayor of MSG. He just, like, knows everyone," said Morgan's co-star Daniel Radcliffe of Harry Potter fame, who attended a game courtside with Morgan this past season.

Tina Fey, Morgan's co-star on "30 Rock," said in an interview on "The Today Show" last week that Morgan is the source of her courtside seat at Knicks games. She was optimistic about being a guest of his again at the NBA Finals when they return to New York.

"Sitting next to Tracy Morgan at a Knicks game is an experience," Stiller said to Howard Stern. "My son's 20 now, but sitting next to Tracy Morgan when he was 10, Tracy Morgan's pointing out all the Knick dancers and telling him what he wants to do."

"Don't spill beer on the parquet and don't get Reggie Miller mad," Morgan told MSG Network about the unofficial rules of sitting courtside. "That's basketball. That was me in the projects, T-shirt backwards, tag hanging out, sneakers untied, snapping on everybody on the court, criticizing everybody's game."

Lee became famous as a Knicks superfan for his trash-talking courtside exchanges with Michael Jordan and Reggie Miller in the 1990s, but he's been going to games at Madison Square Garden for 60 years. He initially bought season tickets ahead of Patrick Ewing's rookie season in 1985.

"My father started taking me 8, 9 years old, and my father is a great, great musician … his lawyer had season tickets to the yellow seats," Lee during an NPR interview recently. "May 8th, 1970, Game 7, he said, 'You go to the game.' I was at the Willis Reed/Walt Frazier game, where the Knicks won their first NBA championship. So I said, 'Lord, if I ever make any money, I just want to get season tickets.'"

After Knicks forward OG Anunoby nearly ran over Hathaway while seated courtside at Madison Square Garden last season – she called it a "bucket-list moment" on Instagram – Hathaway explained her fandom on "The Jimmy Fallon Show."

"I'm very chill. I'm very loving and calm. But I'm also the type of fan that I considered wearing an OG (Anunoby) jersey out here today," Hathaway told Fallon on April 29. "… When I'm at the game, I want them to know that I know who they are and that they're going to win. … I want them to know you can do no wrong. I'm trying to be a gentle, loving motherly fan."

"I love when Anne supports," Anunoby said at the Forbes Iconoclast Summit in June 2025.

But Hathaway, a Brooklyn native, also has a deeper connection to the team related to her childhood.

"The Knicks, to me, that's where I have a fairytale feeling whenever I go to The Garden and I see them," Hathaway told ESPN's Sportish, "because when I was growing up, going to a game was such a huge deal and the closest we ever got was nosebleed, and I remember looking down and seeing the people who sat close up and some people got to sit courtside."

"And so when I get to go to The Garden now and I get to sit in those beautiful seats," she continued, "I'm like, 'Oh my God, 8-year-old me is up there looking down and I'm one of those people now.' It's so special and I love the team. I'm such a huge fan of Jalen Brunson. I think he's such a brilliant player and such a phenomenal leader."

Rapper Fat Joe has been a fixture at Knicks games over the years and made some headlines earlier this postseason when he revealed the Cleveland Cavaliers took away his courtside tickets to Game 4 of the Eastern Conference finals.

The Bronx-born entertainer told Eli Manning in 2023 he "was just born into the Knicks" and would sit in the highest parts of Madison Square Garden growing up as a fan.

"I used to see Michael Jordan this little, the last (row)," Fat Joe said on "The Eli Manning Show," while squeezing his fingers together. "… Something I do courtside at the Knicks game, I always give a prayer appreciative of being here and not being all the way at the top."

The "Back to the Future" star and longtime Parkinson's Disease advocate has been a regular at Madison Square Garden for decades along with his wife, Tracy Pollan. He's been pictured seated with Stiller and Chalamet courtside this season.

The arena will often show a clip from Fox's role as Marty McFly before showing him on the jumbotron to Knicks fans. He reportedly received a standing ovation from the crowd during Game 1 of the Eastern Conference finals.

The origins of Fox's Knicks fandom are unknown, but the Canadian-born actor was watching games long before this current run.

Hargitay's relationship with Knicks star Jalen Brunson has been a constant the past couple years, with the two often hugging after wins at Madison Square Garden. Stiller has said Hargitay is "the envy of every other Knicks fan, Knicks celebrity fan" because of her bond with Brunson.

"How it started is they let me know Jalen is a big fan, and I was so flattered and thrilled because I was such a huge fan," the "Law and Order: SVU" star said on NBC's Late Night with Seth Meyers. "I think Jalen sort of grew up on 'SVU' … He felt, as many people do, that intimacy and safety that one does growing up on 'SVU.'"

Brunson said he would often watch "Law and Order" with his father, former NBA player and current Knicks assistant coach Rick Brunson. Jalen Brunson told Hargitay he plans to attend her new Broadway show, "Every Little Thing" after the Knicks' NBA Finals run is over, according to NBC. He previously attended the premiere of her recent HBO documentary.

"I’ve never been like super, super starstruck. I saw her and I was like, 'Oh, (wow),'" Brunson said during a May 2025 episode of his "The Roommates Show" podcast, which he hosts alongside teammate Josh Hart. "Then, the first time we met, it was awesome, we talked and everything."

It's unclear how long Fallon has been a Knicks fan, but several current players have been on "The Tonight Show" in recent years and his presence at playoff games this spring produced a noteworthy gag initiated by Knicks forward Josh Hart.

Cameras originally caught Hart untying Fallon's shoe as Hart was leaving the Madison Square Garden court during a 137-98 blowout win over the Philadelphia 76ers in the Eastern Conference semifinals. Fallon then attended Game 1 of the Eastern Conference finals with his daughter, when the Knicks erased a 22-point deficit in the fourth quarter to beat the Cavaliers.

Fallon recounted on the May 20 edition of "The Tonight Show" that when the Knicks were losing, he had his daughter untie his shoe to help encourage a potential comeback. Afterwards, as everybody inside Madison Square Garden celebrated the win, "Josh Hart runs by me and he unties my other shoe," Fallon revealed.
