Oklahoma City Thunder

With 46 days 'til the NBA's opening day, Kevin Durant is in hardcore relax-mode -- with hookah pipes and Segway scooters.

The 24-year-old Oklahoma City Thunder superstar was rollin' around Barcelona yesterday on the two-wheeled machine (sportin' a helmet for safety) ... before chillin' out at a smoke shop.

Durant seems to be a big fan of hookah shops -- he's been spotted puffin' away all over the world in places like Chicago, Minnesota and even Hong Kong.

Kevin's penchant for puffin' might also explain why he was chillin' with Justin Bieber recently -- those guys might have more in common than we thought.

It's not every day an NBA superstar like Kevin Durant gives you advice on something he knows all about -- SPORTS!

So, watch KD and his fellow hoopsters (one real, one from a movie) drop some knowledge ... listen up, Harv!

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 ...

Just hours after inking a deal with Roc Nation Sports, NBA superstar Kevin Durant celebrated at the most obvious place ever ... Jay-Z's 40/40 club in NYC.

Jay-Z is putting Jerry McGuire to shame -- because his budding sports agency just signed three-time NBA all-star Kevin Durant.

The OKC Thunder superstar just posted an Instagram of he and Jay signing docs that make him Roc Nation Sport's newest client.

Durant is the latest in a growing list of HUGE athletes jumping ship to Jay's new venture ... like NY Yankee Robinson Cano, NASCAR superstar Dale Earnhardt Jr., and NY Jet Geno Smith

Durant is Jigga's first NBA star.

NBA stars have much better things to do with their time than watch the NBA Finals ... so says OKC Thunder point guard Russell Westbrook -- the second NBA'er to admit missing what the rest of America watched.

Russell (who missed most of the playoffs after tearing his right meniscus) was out in L.A. Friday when our photog asked the All-Star (who was walking without crutches!) what he thought of the Miami Heat's epic win in Game 7 of a nail-biting series.

But Russell -- just like fellow b-baller Dwight Howard -- says he didn't bother to watch the game!

Oklahoma City Thunder all-star Kevin Durant has overcome his fear of spider-ly lawsuits ... TMZ has learned his legal war over the nickname "Durantula" has finally come to an end.

TMZ broke the story ... Durant was sued by former Public Enemy guitarist Mark Durante, who claimed he had trademarked the name and used it to sell merchandise long before KD came along. Durante wanted a judge to stop KD from using it.

KD responded, arguing that he didn't give himself the moniker and never used it to make money. Durant also said no one would ever confuse him with Durante anyway ... probably a safe bet.

But now it's all water under the bridge ... TMZ has learned that Durant and Durante have reached a private settlement and the lawsuit has been dismissed with prejudice ... meaning Durante can never file it again.

Both sides even agreed to pay their own attorneys' fees.

And now, a song.

Kevin Durant is fighting back against a lawsuit claiming he stole the nickname "Durantula" from a 1980s musician ... arguing that he didn't give himself the moniker and doesn't even use it to make money.

As TMZ first reported, the Oklahoma City Thunder star was sued by guitarist Mark Durante, who claimed he had trademarked the name and used it to sell merchandise long before KD came along.

But in his response -- filed earlier this month in Illinois Federal Court -- Durant claims the media and his fans have been calling him by the name his whole career. Durant says he has NEVER used the name to sell merchandise ... so Durante's lawsuit has no merit.

In addition, Durant claims that no one would ever confuse him with Durante (who has played with the likes of Public Enemy, The Aliens and The Next Big Thing).

KD wants the lawsuit tossed completely and wants Durante to cover his legal fees.

Hoops superstar Kevin Durant is one game away from losing the NBA Finals, and now one lawsuit away from losing his famous nickname -- "Durantula" -- because a guitarist claims KD jacked it from him.

Durant was sued today in Federal Court by a guy named Mark Durante -- a guitarist who, according to the lawsuit, was a big deal in the 80s ... playing with Public Enemy, The Aliens, The Next Big Thing, and (our favorite) The Revolting Cocks.

TMZ obtained a copy of the lawsuit, in which Durante says he adopted the name "Durantula" for his "on-stage and performance persona" -- and has used it to market "music, recordings, apparel, t-shirts, guitars, and related merchandise."

Meanwhile, sports fans have adopted the handle for the Oklahoma City Thunder star and current NBA scoring champ.

Durante claims he sent KD's people a couple letters "demanding they stop using the nickname" -- but says Durant's reps claimed he wasn't using it.

In the suit though, Durante claims Nike has used the moniker to launch a shoe campaign -- and KD himself signed "Durantula" on basketballs that are for sale through his website.

The guitarist says he registered the "Durantula" trademark. He's suing for damages and an injunction stopping KD from using the name.
