Oklahoma City Thunder

Good news OKC fans ... Victor Oladipo says he's already been in contact with his new teammate Russell Westbrook ... and they're already drawing up a battle plan for next season.

Oladipo -- who was just traded to the Thunder 3 weeks ago -- joined the guys on the "TMZ Sports" TV show (airs Friday night on FS1) and talked about how he's already bonding with his new squad.

In fact, we asked if he was ready to take over for Kevin Durant -- you gotta check out his answer.

OKC Thunder fans are gonna love this ... Serge Ibaka says he's not sweating rumors of Kevin Durant bolting the Sooner state ... proclaiming to TMZ Sports he's 100% sure KD's sticking around.

Rumblings of Durant eyeing the Lakers in free agency have been white hot lately ... but when we got Ibaka out in Beverly Hills he seemed certain KD -- and Russell Westbrook -- were lifelong Okies.

"Everybody's staying."

Cops say they can't find a shred of evidence that proves OKC Thunder co-owner was trying to kill himself when he slammed his SUV into a concrete bridge back in March ... despite a 2 month investigation.

Aubrey McClendon had been charged with conspiracy hours before the crash for his alleged role in an illegal energy scheme ... and many people thought he took his own life out of shame.

But the Oklahoma City Police Dept. says a team of detectives and accident experts looked into the crash ... and spoke with a bunch of McClendon's friends and say there's nothing that points to suicide.

Now, cops also say they can't be 100% certain ... but at this point, they're convinced he didn't crash on purpose.

The coroner determined McClendon died from blunt force trauma -- but his body was so badly burned in the fire that ensued, they needed to bring in a dentist to identify his body.

Be careful Kevin Durant ... there's a 4'11" Hollywood star who says if you bolt Oklahoma City in free agency ... she'll KICK THE EVER-LOVING CRAP OUT OF YOU.

Don't pity the loser ... especially when the loser's made more than $100 MILLION ... so says Riff Raff.

The rapper (and NBA superfan) was out in NYC when we asked if he feels bad for Kevin Durant after the OKC Thunder failed to close out the Warriors, despite big leads in games 6 and 7.

Long story short ... Riff says Durant's still his homie -- but it's hard to feel bad for a guy who's still RICH.

Also, Riff says it's not entirely KD's fault -- blaming Lil B for sticking him with the Based God curse.

OKC Thunder co-owner Aubrey McClendon "tapped the brakes" several times before his SUV crashed into a bridge ... but cops say they aren't clear if that means he WASN'T trying to kill himself.

56-year-old McClendon died in the March 2nd accident -- after hitting an Oklahoma City bridge at such a high rate of speed, his SUV exploded in flames almost immediately.

In a news conference in OKC moments ago, officials say McClendon's car was going 88 mph 5 seconds before impact ... and 78 mph at the moment of the crash.

Cops say McClendon tapped his brakes several times during the final 5 seconds -- but cops aren't considering it "breakage" because he stopped touching the brakes 31 feet from the wall.

The medical examiner says it doesn't appear McClendon had a medical episode in the final moments -- fueling theories the crash was a suicide.

It's important to note that McClendon had been indicted on a conspiracy charge just hours before the crash -- and was facing prison time if convicted.

Cops are still investigating the crash -- talking with people he was close with ... including co-workers.

Several good Samaritans ... including someone who appeared to be a doctor or nurse ... stopped to try to help Aubrey McClendon after his car crash -- but the fire proved to be too dangerous.

TMZ Sports obtained the 911 calls from the crash -- one caller says he actually witnessed the impact. The witnesses say McClendon's SUV swerved and crashed into the underpass and caught fire.

Another witness says people were running up to the car to try to help ... but noted the fire was "really escalating."

Eventually, the car burst into flames and another witness told 911 ... "There were people standing up there by the vehicle, which doesn't seem very smart to me."

Oklahoma City Police say suicide has NOT been ruled out in the fiery car crash that killed OKC Thunder co-owner Aubrey McClendon ... TMZ Sports has learned.

As we reported ... McClendon died when his car smashed into a bridge at an incredible high rate of speed Wednesday morning ... hours after he was indicted on a federal conspiracy charge that carries up to a 10 year prison sentence.

We spoke with OKC Police Dept Captain Paco Balderrama who told us ... cops are working on several possible theories that led to his death -- ranging from suicide to a medical episode behind the wheel.

"Anything is possible," Capt. Balderrama said ... "At this point we just don't know."

Cops say McClendon was NOT wearing a seat belt at the time of the crash -- and he made no attempt to slow down before impact.

OKC Thunder players Anthony Morrow and Andre Roberson say they're praying for the family of co-owner Aubrey McClendon ... who was killed Wednesday morning in a horrific car accident.

Aubrey McClendon -- co-owner of the OKC Thunder -- crashed his car into a bridge and killed himself in what appears to be a suicide mission ... one day after he was charged with conspiracy.

Even megastars like Russell Westbrook have bouncer drama at Hollywood nightclubs -- 'cause the NBA superstar got stopped at one of the hottest bars in L.A. Monday night 'cause the bouncer didn't know who he was.

The Oklahoma City Thunder superstar hit up The Nice Guy -- often frequented by huge stars like Justin Bieber, Gigi Hadid and Leonardo DiCaprio -- when the bouncer pumped the brakes at the door.

Oklahoma City Thunder superstar Russell Westbrook is getting a ring even before the NBA season begins -- he's marrying his longtime GF this weekend in a pretty baller setting.

TMZ Sports has learned ... Russell and Nina Earl will walk down the aisle in Beverly Hills on Saturday -- just about a year after they started planning. As we reported, they announced their engagement last September ... when Nina posted a pic of her $700k ring!

We're told the couple is having a low-key ceremony, and wants to keep the exact location under wraps, but trust us ... the wedding pics will be spectacular.

Mazel tov!

You can finally share DNA with Kevin Durant ... if the price is right ... because the NBA superstar's actual USED straw has hit the auction block ... for real.

In fact, the straw is the REAL piece of plastic KD sucked from during a SONIC fast food commercial the NBA star shot back in March, when he was promoting the Kevin Durant Signature Slush.

The straw also comes with a certificate of authenticity personally signed by KD that reads, "This is the actual straw from the Candy Slush that Kevin Durant (KD) had on the set of a SONIC commercial shot on March 26, 2015."

There's more ... Sonic is also auctioning off the ACTUAL candy from KD's slush ... which also come with a C.O.A.

Don't worry, it's not some cheap stunt to make a few extra bucks -- the auction benefits the Limeades for Learning program ... which raises money for educational programs across the country.

Oklahoma City Thunder star Kevin Durant honored ESPN legend Stuart Scott on the court last night ... with a hand-written tribute to the anchor penned on his sneakers.

10:06 AM PT -- IT'S A $700,000 RING!!!!

We've learned ... it was made by Jason of Beverly Hills ... who's made engagement rings for all sorts of stars including Gabrielle Union and Evelyn Lozada.

As for Russell's ring -- we're told it's a 6-piece elongated cushion cut ring with VVS clarity ... and in total, the whole thing is worth $700k.

We're told Russell knew exactly what he wanted when he hit up Jason's shop. It was very important to him that he got a ring with the highest quality possible.

Dude did a helluva job.

Oklahoma City Thunder star Russell Westbrook is the next NBA star in line for a wedding -- 'cause he popped the question last night ... with a massive diamond ring ... and his GF said yes!

Westbrook and longtime GF Nina Earl made the announcement on social media Wednesday night ... showing off the gargantuan rock with a caption that read, "Nothing even matters..@ninamri3_ forever my lady! LOVE YOU!!!!"

Earl is a former UCLA basketball player -- and the two met during their college days ... before Westbrook signed his $80 MILLION contract extension.
