New York Knicks

Paul Pierce really IS the "Truth" -- 'cause the Celtics legend kept his word and started an eight-hour trek to the Fox lot after guaranteeing his old team would beat the Knicks on Wednesday ... and he's documenting the whole journey.

Pierce talked a big game prior to Game 2 of the Eastern Conference semifinals ... saying if the Cs didn't even things up at 1-1, he'd use his legs as transportation to get to work the next day.

"If the Celtics lose Game two at home, I'm walking here tomorrow," Pierce said on "Speak."

"Fifteen miles! I'm walking here! In my robe, no shoes on, barefoot, if the Celtics lose tonight."

The Celtics vs. Knicks action wasn't just limited to inside TD Garden on Wednesday night ... some of their fans got into a wild brawl outside the venue as well -- and a good portion of the scrap was captured on video.

Check it out ... just after New York stunned Boston with another come-from-behind road win, several people clad in blue and orange mixed it up with some C's backers.

A man in a Paul Pierce jersey appeared to get the better of one Knicks fan -- bloodying him with a flurry of punches. Nearby, a Jalen Brunson supporter clearly had his hands full with his rival too.

Timothée Chalamet had a pretty good reason to let Kylie Jenner fly solo at the Met Gala ... his NBA team was playing an important playoff game, and he had to watch!!!

The actor, who is a big Knicks fan, was nowhere to be found at Monday's Met Gala in New York City ... instead, he was tuning in to watch the Knicks play the Boston Celtics in Game 1 of their series.

Timothée may have made the right call here ... the Knicks won in thrilling fashion, storming back from a 20-point deficit to shock the defending-champion Celtics in overtime, 108-105, to steal home court advantage in the best-of-7 series.

Jalen Brunson's game-winning shot to send the Knicks to the second round of the NBA playoffs sent New York into a frenzy ... including former star Stephon Marbury -- who went bonkers over the massive victory!!

The Brooklyn native went live on his Instagram for the final few minutes of the Knicks' Game 6 matchup against the Detroit Pistons ... and we're happy he did -- 'cause the reaction was priceless.

Like the rest of New York, Marbury was on Cloud 9 when Brunson hit the go-ahead three-point shot with 4.3 seconds to go ... and he couldn't contain his excitement.

A$AP Rocky couldn't contain his excitement reacting to Jalen Brunson's KILLER CROSSOVER that put the Knicks into the 2nd Round of the NBA Playoffs -- and took the streets to celebrate!!!

TMZ Hip Hop caught Lord Pretty Flacko out in Harlem catching the game at Melba's restaurant right at the moment his Knicks clinched the win over Detroit ... with a nail-biting game-winner from the Kia Clutch Player of the Year.

The DoorDash-fueled "Crosstown Express" Knicks bus also arrived at the soul food spot, and Rocky and fans took full advantage of the basketball hoop attached to the vehicle!!!

Detroit is riding high after snapping its 15-game playoff losing streak against the New York Knicks on Monday ... but former Piston Ben Wallace tells TMZ Sports the current squad isn't a bunch of "Bad Boys" -- they've earned their own identity!!

We caught up with Big Ben out at LAX on Tuesday ... and while he knows there's a ton of basketball left, he believes his old team can pull off the first-round upset with the series tied at 1-1.

"The guy's been playing well," he said. "The guy's playing hard, playing together. We're gonna go out there and just see what happens. I think the guys are excited about being out there, being able to be back in the playoffs. We know anytime getting to the playoffs, anything's possible."

50 Cent and Joe Budden have been going tit for tat for weeks on social media ... but it was all good when they came face-to-face at the Knicks heated playoff game last night!!!

A source close to 50 Cent’s floor seat act tells TMZ Hip Hop the G-Unit general -- along with Fat Joe -- were invited guests of Madison Square Garden and were supporting the NYK.

We’re told 50 had no idea Budden was even at the game until they showed 50 on the Jumbotron -- and saw Joe cheering for him on the big screen.

Josh Hart asked and he received -- Suni Lee returned to Madison Square Garden to watch the Knicks' playoff game ... but unlike her last visit, the Knicks fell short this time around.

Game 2 of New York's first-round series against the Detroit Pistons went down on Monday ... and the stunning six-time Olympic medalist had a courtside seat for the matchup.

Her appearance comes after Hart jokingly pleaded for her return in a convo with Jalen Brunson on their "Roommates Show" podcast ... when he claimed their teammate, OG Anunoby, plays better when she's present -- after all, he had 32 points when she observed his game on April 6.

Nearly a month after he upchucked his dinner onto the floor at Madison Square Garden ... Tracy Morgan was back courtside watching his Knicks -- and this time, there were no stomach issues in sight.

The 56-year-old comedian pulled up to New York's Tuesday night tilt with the Boston Celtics for the first time since his now-infamous March 17 incident ... and his favorite team welcomed him back with open arms.

They showed him on the jumbotron, and fans roared with applause when they saw he was back. Morgan responded with some blown kisses and a "Go Knicks!" message.

Pete Davidson and Elsie Hewitt took their blossoming romance to Madison Square Garden Sunday night to watch the New York Knicks play the Phoenix Suns.

The new couple sat courtside in the packed NYC arena — and they seemed to really enjoy the game as well as each other.

Check out photos, which show the comedian and the model walking hand-in-hand through a crowd and sitting side-by-side in their seats with big smiles as the Suns beat the Knicks 112 to 98.

Russell Wilson put pen to paper on his New York Giants contract less than 24 hours ago ... but he's already getting some reps in -- throwing passes to fans while sitting courtside at a Knicks game!

Mr. Unlimited made the trip across the Hudson River to catch some hoops at the Garden, with New York welcoming James Harden and the Clippers into town.

It was a warm reception for the Giants' newest signal caller ... who tossed an autographed ball a few rows up.

Tracy Morgan's not going into hiding after his very public vomiting episode earlier this week ... TMZ Sports has learned he's actually trying to get out to another Knicks game as soon as he can.

As you know, the comedian was hospitalized on Monday after a bad bout with food poisoning caused him to upchuck all over the Madison Square Garden floor during New York's game with Miami.

Some had wondered if he'd just opt to catch his favorite team from the couch for the rest of the season from here ... but a source close to Morgan says he will be back at MSG despite the messy scene.

Travis Kelce and Taylor Swift have kept a low profile since the Super Bowl thrashing, but there's a chance the superstar couple may soon reemerge at the World's Most Famous Arena to catch a Knicks game!

Trav and bro Jason chopped it up with Ben Stiller on this week's episode of "New Heights," with the actor telling the story of meeting Swift at a game a decade ago.

"I was there with my son," Stiller said. "We FaceTimed my daughter, who is a huge Swiftie. She's 23 now, we had the best time. She was incredible."

The biggest honor in entertainment means nothing to Ben Stiller -- at least in comparison to his beloved New York Knicks' success ... 'cause the actor said he'd rather have an NBA title than an Oscar!!

The comedy legend and "Severance" director admitted just how crazy he is about his basketball team on the latest episode of Travis and Jason Kelce's "New Heights" podcast ... when he admitted he'd be perfectly content with never getting a statuette in his trophy case -- as long as Larry O'Brien comes back to New York.

Stiller joked a Knicks title is a lot more likely ... so he's "definitely down" for it to play out like that.

Steven Spielberg’s daughter had a front-row seat to an unforgettable moment at her first-ever courtside NBA game Monday night—sitting next to Tracy Morgan as he threw up all over the court at the New York Knicks game.

Destry Allyn Spielberg took to Instagram on Tuesday to make light of the awkward moment ... sharing a hilarious photo of herself looking absolutely disgusted as she sat one seat away from the 'SNL' star while he got sick.

She jokes that she "had a great time" in her first meme-worthy photo, then followed up with a snap of Tracy spewing vomit, overlaid with a shrugging emoji. Hey, s*** happens!

Tracy Morgan's medical emergency Monday night all stemmed from some bad grub he had eaten earlier in the day.

The comedian said in an Instagram post Tuesday morning he projectile vomited all over the Madison Square Garden floor during the Knicks vs. Heat game because he was dealing with food poisoning.

It's unclear what he ingested to cause the ailment -- but Morgan fans can breathe a bit easier knowing the issue wasn't anything more sinister.
