New York Knicks

It's official ... NY Knicks star Iman Shumpert's in a full-on RELATIONSHIP with singer Teyana Taylor -- and TMZ Sports has the video proof.

There had been rumors the two were hookin' up, but this week the two set the record straight -- hitting up "The Equalizer" premiere together in NYC ... with all sorts of PDA.

Check out the clip -- Iman bristles at the notion that their relationship was fake and solidifies the union by dropping the all important "bae" when referring to Taylor.

BONUS -- they even had their very first couple's activity ... teaming up to interview "Power" star Naturi Naughton right on the street.

Nick Cannon got treated like an ENEMY at a Knicks game at Madison Square Garden this week ... when the crowd turned and hammered him with BOOS ... and TMZ Sports has the footage.

Cannon was shooting a segment for "America's Got Talent" on April 2nd -- during halftime of the Knicks vs. Nets game.

We're told producers came out first and asked the crowd to cheer ... but when Nick took the floor, the crowd showered him with hate.

At one point, Nick told the crowd, "Go ahead. Boo louder. Get it outta your system!" But the reverse psychology didn't work.

Eventually, Nick tried to pull off a trick shot (with the help of producers) ... but that didn't work either and the booing continued until the crowd got tired.

Hey, keep your head up Nick ... New Yorkers even booed Tim Tebow during a Yankees game back in 2012.

Who boos Tim Tebow?!

Emmy Rossum is a die hard Knicks fan ... DIE HARD ... and she doesn't take kindly to people who jumped ship to root for the Nets because Jay Z told them to.

Rossum was at LAX this weekend -- proudly rockin' her Knicks hat -- when she admitted it's been hard being a NYK fan over the years, but says ... "I love my team so I don't give up on them."

Then she fired the shot -- "I didn't just hop to the Nets 'cause they were cool ... like other people."

Glen "Big Baby" Davis is adjusting pretty well to life in L.A. ... crushing it on the court -- and also at the nightclubs ... and TMZ Sports has the video proof.

We spotted Davis leaving DBA nightclub last night ... with (at least) THREE hot chicks in tow.

After they got in his waiting SUV, a bunch of other chicks flocked to Glen's ride ... like skeezer moths to a rich and famous flame.

Aside from chick wranglin', Davis also talked basketball -- telling us his L.A. Clipppers are gonna win the NBA championship.

There's a new basketball team doing business in Harlem ... a couple of former New York Knicks -- who just officially OPENED their first pizza joint together ... TMZ Sports has learned.

John Starks and Anthony Mason finally cut the ribbon on the first NYC location of Custom Fuel Pizza -- a chain that started in D.C.

The duo is pumped about being investors in the franchise (they previously told us they want to challenge Peyton Manning for the pizza title) ... and last night at the grand opening party, John and Anthony gushed about how they plan to change the pizza game forever.

Metta World Peace isn't letting unemployment stop him from dominating the basketball courts ... of West Los Angeles.

Just days after Metta was released by the Knicks, Peace surfaced at Equinox Gym in L.A. on March 1st -- hooping with some not-quite-pro level competition.

Check out the video ... you can see Metta's teammates aren't exactly throwing the rock his way -- and we're told it's because his shot was straight up broke that day. Hey, it happens.

But there's this -- everyone we spoke to said Metta couldn't have been nicer -- and took time to shake hands and talk with people afterward.

New York Knicks player Raymond Felton committed ADULTERY during his marriage ... so says his estranged wife in divorce docs obtained by TMZ Sports.

Ariane Raymondo Felton -- the same woman who ratted Raymond out to the cops about his illegal firearm -- filed docs last month in a New York court seeking to end their 18-month marriage.

But in the docs, Ariane penciled in that she's divorcing Felton because of "adultery."

Ariane doesn't go into detail about the adultery allegations ... but in the docs, she does request the judge throw out their pre-nup. It seems she wants the prenup tossed out on the count of the alleged cheating, but she doesn't explain why.

New York Knicks guard Raymond Felton was arrested on gun charges Tuesday ... after his estranged wife ordered her attorney to bring the player's gun to an NYPD precinct.

According to NYPD, Ariane Raymondo-Felton's attorney handed over the semi-automatic Belgian-made pistol late Monday night.

The following morning, Ray turned himself in to police for questioning.

It's unclear at this point why Felton's wife of just 19 months brought the gun to cops. She filed for divorce last week.

The NBA player was eventually booked for two felonies -- 2nd and 3rd degree possession of a firearm -- as well as 4th degree possession ... a misdemeanor.

Felton went to the Manhattan precinct to deal with the gun trouble ... right after the Knicks lost another heart breaker to the Dallas Mavericks.

Kenyon Martin doesn't just think those special sleeved NBA jerseys are ugly ... he thinks they're emasculating -- telling TMZ Sports they belong in the WNBA!

The New York Knicks star was leaving Greystone Manor this weekend ... when we asked how he felt about the sleeved unis NBA teams had to wear during the Christmas Day games.

"I think they're WNBA jerseys," Martin said.

"I had to go with it, it's the job, you got to wear the company uniform ... so, it is what it is."

He adds, "It's all about money at the end of the day ... do I agree with it? No. Do I understand it? Yeah."

LeBron James would be in for a rude awakening if his Miami Heat ever found a 'suped up time travelin' DeLorean ... 'cause Charles Oakley says his Knicks squad would've probably put a hurtin' on LBJ's team.

Of course, Oakley was likely referring to his '92-'93 Knicks squad ... which was packed with superstars like Patrick Ewing, John Starks and Anthony Mason.

The Knicks went 60-22 that year but lost in the Eastern Conference Finals to Michael Jordan and the Bulls.

Fun Fact -- the coach of the Knicks was Pat Riley ... who's now the President of the Heat.

NBA star Kenyon Martin has picked a longshot to win the Super Bowl ... a reaaaaal longshot.

Martin was leaving a shoe store in Harlem last night when we asked for his pick to win the big game -- his answer? THE COWBOYS!!!

Obviously, there's a bit of a problem with that pick ... since, you know, they're not exactly playing.

Michelle Rodriguez upstaged the NY Knicks from her courtside seats by drunkenly posing for ridiculous selfies ... and snuggling up to smoking hot model Cara Delevingne.

Michelle was all over Cara -- and looked totally out of it -- while putting on what has to be the greatest party chick clinic in NBA history last night at Madison Square Garden.

It's unclear if Michelle -- who's proudly stated going "both ways" in the past -- scored after the game ... but click through the gallery.

Looks to us like Michelle put in enough work to earn some overtime.

Oh, the Knicks won the game. But who cares?

Stay in school, kids ... because if you do well, Carmelo Anthony will give you free Knicks tickets!!! At least that's what he did in Baltimore this week.

Melo and teammate Iman Shumpert dropped by the Carmelo Anthony Youth Development Center in MD to spend some time with the kids in the program, and Melo rewarded the 15 Students of the Month with free Knicks tickets to Thursday's game in Baltimore (against the Wizards).

Anthony gave each student 2 tickets ... handing out 30 total ... but he didn't forget about the non-Students of the Month. We're told he handed out t-shirts to everyone. And they all had a blast.

Talk about a real winner -- and not just because the Knicks trounced the Wizards 98-89.

Dean "The Dream" Meminger -- who helped the NY Knicks clinch the 1973 NBA title -- was found dead in his hotel room Friday ... wearing his championship ring.

Meminger was found unconscious inside his NYC hotel room by staff members after failing to check out. He was pronounced dead on the scene. There were no signs of trauma. A witness reportedly saw "white stuff" oozing out of his nose.

Meminger had long suffered from drug addiction, including cocaine, even in his pro-basketball days. He almost died in a rooming house fire where he was allegedly smoking crack back in 2009.

The 65-year-old was a first round draft pick back in 1971.

Justin Bieber has some big friends ... we're talkin' 7-footers ... and they've got JB's back no matter what, so says NBA superstar (and full on Belieber) Tyson Chandler.

Earlier this week, Bieber tweeted a photo of himself (sans shirt, of course) hanging out with Chandler and Oklahoma City Thunder superstar Kevin Durant.

Everyone sorta wondered how they all know each other ... and what they were all doing at Bieber's mansion.

Well, last night, we found 7'1" Chandler leaving a party in Beverly Hills and he told us everything ... except why Bieber has so much trouble keeping his shirt on.

The mystery continues ...

Dear Los Angeles Lakers fans,

We're sorry to inform you ... it doesn't seem very likely Carmelo Anthony will be dishing to Kobe Bryant any time soon, despite reports to the contrary.

Anthony was leaving Cecconi's in West Hollywood this week when we asked straight up if he could see himself in purple and gold after his contract with the Knicks runs out.

CA's response? "Ummmmm, I doubt it."

Carmelo teased us a little bit ... saying he owns purple and gold shoes -- but made it pretty clear he has no plans to wear them on the hardwood.

Anthony also told TMZ ... he's NOT secretly plotting with LeBron James to join the same NBA squad ... though he admits, they're pretty damn good when they play together.

Still, don't count out the Lakers entirely ... 'cause when the time comes, you can bet L.A. will bust out the checkbook -- and nothing changes a mind like a couple of zeros.
