Cleveland Cavaliers

Beware, Kyrie Irving ... Kenny Smith thinks a horrible breakup song should be written about you ... 'cause the ex-NBA star says Irving should be the next man up ... to date Taylor Swift.

Smith was out in L.A. when we wanted to know if it's time for the newly single T-Sweezy to give the NBA world a chance ... since it doesn't seem to be working with the actors and singers.

Kenny says YES ... and he has just the guy ... Cleveland Cavs star Kyrie Irving, who he says would be right up Swift's alley 'cause of where he's from ... and what he likes.

Cleveland Cavs star Iman Shumpert was arrested for driving under the influence of marijuana back in August ... TMZ Sports has learned.

If the Stanley Cup can go on a donut run ... so can the Larry O'Brien trophy!

Cleveland Cavs stud Tristan Thompson grabbed the NBA championship hardware and took it on a little getaway to Canada ... where he's been giving it a tour of his home country.

But the best part ... he took Larry to Tim Hortons ... a famous coffee and donut shop chain up north where Sidney Crosby brought the NHL's biggest prize back in July.

"I saw Sidney Crosby brought the Stanley Cup to @timhortons so only right I brought Larry!" Tristan tweeted.

Maybe Peyton will road trip with the Vince Lombardi Trophy next ... not like he's got anything else to do.

LeBron James is putting that new $100 million contract to good use, 'cause the Cavs superstar brought 5,000 kids and their families to an amusement park on Tuesday.

The annual trip to Cedar Point in Sandusky, Ohio encourages Akron kiddos to focus on their education before entering LBJ's "I Promise" initiative -- which offers a free college education after high school.

TMZ Sports spoke with a rep from CP, who tells us, "It’s an honor to work with a wonderful, dedicated group of people who provide so much to Northeast Ohio – and we’re happy to provide a 'Best Day' experience for their program families here at the park.”

LeBron teamed up with Chase Bank to help pay for the shindig ... which also offers an opportunity to attend a sit-down convo with the King himself.

Cleveland Cavs forward Dahntay Jones added a ring in June ... but lost 400 kicks in July ... 'cause more than 200 pairs from his prized shoe collection were just auctioned off ... and he's PISSED.

Jones kept 208 pairs of rare Nikes in a storage facility in Atlanta for years ... but not just any old kicks, some of the shoes were ultra-rare ... including sample kicks made especially for Fat Joe.

But the facility claims Jones didn't keep up on the payments, so last week, they auctioned of the contents ("Storage Wars" style) ... and the winning bid was around $4,000.

We spoke with Jones who admits he was late on his payments -- but says it was a simple mix-up that could have been easily corrected without having to unload his sneakers.

Jones says his credit card stopped making payments to the facility due to a possible fraud alert (it happens sometimes) ... but says he contacted the facility and told them he would come up with the cash (he's reportedly made $18 mil in the NBA).

Jones says the facility went ahead with the sale anyway ... and now, he's out 1/4 of his beloved shoe collection. He's considering legal action.

By the way, Jones says the outstanding bill was LESS THAN $400.

As for his ex-kicks ... the new owner says he plans to sell them on eBay .. and we're told they'll probably fetch a hefty return.

Everyone seems to love the J.R. Smith tatted tee shirts ... including his own wife -- who rocked J.R.'s body to a prestigious golf course in Ohio Thursday.

Richard Jefferson says he's definitely NOT hangin' 'em up -- telling TMZ Sports he has no plans to retire and wants to ball for "a couple more years."

The 36-year-old Cleveland Cavs star initially announced his retirement in the locker room -- right after his squad beat the Golden State Warriors to win the NBA championship.

But he's been walkin' that statement back ever since -- and Wednesday at The Solution (an IV hydration spa in L.A.) he told us pretty definitely "I'm not retiring."

Question is ... is he gonna stay in Cleveland? We asked. Check out what he said.

Kevin Garnett to the Cavs????

Probably not ... but he got lunch with the coach Tuesday.

Turns out KG is longtime friends with Ty Lue -- and the two hooked up for a fancy lunch yesterday at Crustacean in Bev Hills.

First Kobe ... now Obama??

The President just announced he finally "hung it up" -- and will no longer play competitive basketball games.

54-year-old Obama revealed the move during a phone call with Cleveland Cavs coach Ty Lue -- saying he actually "hung it up about 2 years ago."

The reason? Fear of injury.

"You know, I had too many friends ... seen that achilles pop ... being in a boot for 6 months."

For years, Obama was a regular in pick up games -- and was praised for being a pretty good player. In fact, he once played in a game with LeBron, Dwyane Wade, Magic Johnson, D-Rose and Carmelo Anthony.

Now, it seems those days are over -- but there are reports B.O. wants to own an NBA team after he's done being the leader of the free world.

LeBron James went full Richard Pryor during his speech at the Cavaliers championship parade ... shocking fans and giving TV censors heart attacks.

We can't recall the King ever dropping even a single 4-letter word on camera, but this time on the mic he let loose -- working the stage like a stand-up comedian -- even though kids, including his own, were watching.

Senator Marco Rubio -- a huge Miami Heat fan -- says he's genuinely happy LeBron James won another NBA championship ... because, "I'm not a hater like that."

"I'm happy for him, I'm happy for Cleveland," the junior senator from Florida told us at Reagan National Airport.

LeBron James is channeling his inner-Birdman ... telling his haters straight up, "Put some respeck on my name!"

Bron just issued a love letter to his critics ... putting 'em all on blast for doubting his ability and insinuating he's a crap stirrer behind the scenes.

"They said u lost a step, wasn't explosive as once was, the best days was in the real view, questioned your drive, your leadership, your commitment, you don't have killer instinct, going back home is the worst mistake in your career, he got the coach fired, players traded, won't work between him and Kyrie, Him and Kev won't work, love your teammates to much, there's no way he can deliver a championship in his hometown, etc etc etc.... But guess what THATS NONE OF MY BUSINESS."

Then came the hashtags -- "#StriveForGreatness #ThisOneIsForTheLand #PutSomeRespeckOnMyName Hahahaha!!! Yes sir"

He ain't gonna say it no more.

Madness in Cleveland.

Thousands of Cavs fans have packed the I-X Center next to the airport in Cleveland ... waiting to greet LeBron and company the second the champs step off the team jet!

The scene is crazy ... people decked out in Cavs gear, holding signs, chanting -- and the traffic to get anywhere close to the action is reportedly insane.

The Cavs plane is supposed to land around 12:30 PM ET -- and it should an epic welcoming party.

Stay tuned ...

Charles Oakley was PISSSSED while waiting outside of the Cleveland Cavs locker room after Game 7 Sunday night -- at one point telling security, "Touch me, see what happens."

The 52-year-old NBA great is a Cavs fan -- he's from Cleveland -- and we're guessing he was waiting around to celebrate with the team.

But something went awry -- as captured on video by USA Today's Sam Amick -- and it culminated in Oakley essentially challenging security to step up ... or shut up.

Rihanna ... talkin' trash!!

Didn't take RiRi long to go in on Steph Curry after Game 7 -- throwin' a little shade at the NBA's regular season MVP on Instagram.

Rihanna's a HUUUGE LeBron James fan -- and overloaded her social media with tributes to King James after the Cavs took the title ... even calling him "Bae" at one point.

It's good to be the champ.
