Knicks stars Jalen Brunson and Josh Hart aren’t finished celebrating the team’s championship run yet.

In an exclusive interview with The Post, the NBA champs and Matt Hillman, Hart’s best friend and business partner, pulled back the curtain on their lives after June 13 — when the Knicks clinched the NBA title in a 94-90 win against the Spurs in Game 5 of the 2026 NBA Finals.

“It’s been the most chaotic mix of personal and professional time really ever,” said Hillman, who is the co-host of the “Roommates Show” weekly podcast with Hart and Brunson.

It’s been a non-stop work flow of television appearances, brand deals and new opportunities after the final buzzer rang at Frost Bank Center in San Antonio — and the Roommates have been keeping a secret.

The third edition of their live podcast experience — “The Roommates Show Block Party Presented by DoorDash” — will move from Central Park to Randall’s Island Park on Sept 26 due to high demand for tickets after the Knicks secured their first title in 53 years.

More than 4,000 tickets for this year’s show sold out in 90 seconds, with nearly 8,000 fans left on the waitlist, making this the potential largest live podcast event of all time.

They will welcome special guests including Jose Alvarado, Mariska Hargitay, Jimmy Fallon, Spike Lee, Landry Shamet and more — plus musical performances from Fabolous, Jim Jones, Maino and Dave East.

“I think it’ll be a great opportunity to celebrate with the fans and also celebrate the fans themselves,” Brunson said. “They showed up for us, so I’m just excited to show up for them in a fun and different environment.”

The “Roommates Show” is two and a half years old, having launched in Feb. 2024, and entering its fourth season.

“We kind of started [the podcast] and didn’t really know what the trajectory was going to be,” Hart said. “We didn’t have like a goal in mind. We were just like, ‘You know, let’s start it and just to see if anything comes of it.

“And obviously, two and a half years later, or three seasons in, it’s definitely grown a little bit bigger than we thought it was going to be. But it’s been a fun process… Not every day is fun. It’s very up and down in terms of getting the episode recorded sometimes.”

Hart added that the pair will address the departure of Mitchell Robinson, who signed with the Celtics last month after spending his first eight seasons with the Knicks — among other big moves around the Eastern Conference, during their live show.

Tickets for “The Roommates Show Block Party presented by DoorDash” go on sale, Friday, Aug. 21 at Noon ET.

For Hart, it’s been a balance of accepting new opportunities off of the court, making time for his family and continuing to celebrate being a NBA champion.

“At the end of the day, that [championship] team in its entirety is never going to be back together, you’re not going to have that same locker room, guys are going to go in, guys are gonna go out — so it was [important] that we had a bunch of times where we were able to go out and celebrate as a team and I’ll leave those details out for another day,” Hart said.

The Knicks partied at Chez Margaux, a private supper club, with celebrities after their ticker-tape parade on June 18 — and plenty of photos made the rounds online.

Hillman, who was with Hart for much of the summer, explained that it was overwhelming at times.

“From my perspective… the one thing that caught me by surprise is you never really hear about what happens after the win — you could just kind of think it’s all celebrations and fun,” Hillman said.

“I’ll be honest, I don’t think they got to really even enjoy it until multiple weeks after… when he got to Europe [in July] and then even when he got back [to New York] back from Europe, he had an equally crazy week with appearances at Fanatics Fest and the [2026 FIFA] World Cup and other things.

“From the moment, the buzzer sounds, it’s press, and you do all of these different things, and then it’s trying to celebrate with your teammates out pretty late — and then 6 AM, ‘Good Morning America’, at 7 AM [it’s the] ‘Today Show’

“… So they were just running a million miles an hour for two weeks. And obviously, I was kind of there with him for a lot of it and it was just 24-7. It was brand deals and parades and just integrations into the schedule, it was a lot.”

Hart and Hillman have history.

They became best friends in high school, and Hart moved in with Hillman and his family for two years before he went to play at Villanova.

Hart and Hillham along with their wives, Shannon Hart and Samara Hillman, vacationed together in France — and indulged in wine tastings at Château Lynch-Bages, a winery in the Pauillac appellation of the Bordeaux region in July.

Hart said him and Shannon also enjoyed some R&R in Capri and Rome before heading back to the United States to attend weddings earlier this month.

“I went to Donovan [Mitchell] and Coco [Jones’] wedding and then we just got back from KAT and Jordyn [Woods’],” Hart said.

“It was really nice, both of them were. Really cool ceremonies [and] receptions… They were both good vibes.”

Hart is looking forward to some downtime with Shannon and their three-year-old twin sons, named Hendrix and Haze, before the start of his tenth NBA season.

“We’re out East now,” he said of spending the rest of his summer in The Hamptons. “I think I’m doing like two or three brand [commitments] in the Hamptons. August is kind of my time to just work out and get away from the stuff.”

Hart isn’t the only one securing brand deals.

Shannon, who has 95,000 Instagram followers, recently signed with Digital Brand Architects for representation.

In 2026, she partnered with brands such as, Vita Coco, Maybelline, Maker’s Mark, AT&T, Reeses, and Blueair US.

It’s all led to her next big project, which Hart hinted will be announced soon.
