The rivalry continues ... 

Cris "Cyborg" Justino was quick to congratulate Ronda Rousey after she won the WWE Raw Women's Championship on Sunday ... but not without reminding her who's the "most feared" woman alive.

"Congratulations to the Baddest Woman On The Planet for winning your first of many @wwe championship belt 

Sincerely,

The Most Feared Woman On The Planet."

Cyborg has been trying to get a fight with Ronda for years -- but it never happened. Cyborg previously accused Ronda of ducking her.

There's been talk of the two facing off in WWE down the line -- with Mick Foley even trying to convince Vince McMahon to sign her. 

Judging by her congratulatory note, seems like Cyborg's still down. 

Ronda Rousey has been on Cloud 9 ever since she joined WWE -- with her husband, Travis Browne, telling TMZ Sports she's in "full celebration mode all the time."

Browne was in NYC on his way to SummerSlam on Sunday when we asked how she's handling being the biggest star in WWE ... and Travis told us she's thriving behind the scenes.

You gotta watch the clip ... Browne breaks down why being a WWE superstar is much less stressful for Ronda -- and how walking away from fighting has improved her life.

Browne also says there are huge perks for him -- being the husband of the baddest woman on the planet definitely has its pros!

One of the most famous brothels in the world thinks it can help Tiger Woods get over the hump ... by humping. 

Tiger is getting dangerously close to returning to his old dominating self -- and Sheri's Ranch thinks his rampant sex habit gave him the confidence to kill it on the links. 

"We all love Tiger here at Sheri’s,” Dena, the madam of Sheri’s Ranch says ... "Since Sheri’s is known for keeping secrets, there is no safer place for Tiger to indulge his unquenchable urge for sex with a wide variety of women." 

In fact, they're offering up a 75% discount for the golfer on anything they offer -- and they offer a helluva lot. 

Could it work? Dunno ... but it couldn't hurt.  

The sun has set on Amar'e Stoudemire's time in this awesome Phoenix crash pad ... 'cause the ex-NBA superstar is parting ways with his home of 12 years ... and it sold for $800K!!

TMZ Sports has learned ... Amar'e bought the 3 bed., 4 bath. crib back in 2006 when he was killing it for the Suns ... and decided to put it on the market with David Khalaj from Pro Sports Realty in August 2017.

The place is sick ... it's got a massive built-in aquarium in the living room, an outdoor pool and spa and a gourmet kitchen.

STAT wasn't able to find a buyer for almost a year ... but it finally sold for $800k this past July.

IndyCar driver Robert Wickens was just taken to a hospital by helicopter after a horrifying crash he was involved in on the track ... which sent him and his vehicle spiraling.

HUGE CRASH in Pocono. Ryan Hunter-Reay & Robert Wickens collide, and Wickens gets into the fence. Shades of Scheckter and Brack in Texas 03. Red flag, long delay coming. #IndyCar #ABCSupply500 pic.twitter.com/6JxX0IncHB

Wickens was racing Sunday at Pocono Raceway in Pennsylvania for the ABC Supply 500 Series when he tried passing another driver, Ryan Hunter-Reay, on lap 6 ... but bumped him instead, and got launched into the air and against the side fence in a terrifying collision.

According to IndyCar Series' official Twitter account, Wickens was awake and alert as he was being transported to nearby Lehigh Valley Hospital-Cedar Crest. At least 4 other drivers involved in the wreck were reportedly being treated on the scene as well.

The rest of the race is currently delayed, but it's expected to resume as soon as debris is cleared from the track. 

Story developing ... 

Pearl Jam brought out a very special guest at their Chicago concert this weekend -- none other North Korea's #1 man Dennis Rodman ... who had some, uh, interesting things to say.

The former Bulls star made an appearance Saturday night at PJ's Wrigley Field set and told Chitowners he was thankful for their continued support while he unofficially lobbied for the U.S. with Kim Jong-un ... which unofficially resulted in an actual meeting recently. 

Dennis told the crowd ... "You people here are the only people on this planet Earth [that] gave me support. Thank all you guys!" He continued with a promise to the Windy City, saying when he died ... he'd "make sure" to be buried in Chicago. The audience ate it up.

Eddie Vedder told him to put off his death for as long as possible. Well said.

T.J. Dillashaw is doubling down on his threats to beat Gervonta Davis' ass in the Octagon ... telling TMZ Sports he REALLY wants to show the boxer "what real fighting is all about!!"

T.J. and Gervonta got in an epic Twitter war last week -- trading all kinds of insults -- and actually challenged each other to a fight.

When the UFC superstar dropped by the TMZ newsroom this week ... he took a break from trash-talking Henry Cejudo to tell us he's dead serious about a future tilt with Gervonta.

"This is a guy I would love to step into the Octagon and show him what fighting is really about," Dillashaw says.

Of course ... Gervonta's never fought in the Octagon before -- so the match would take some time to come together.

But ... T.J. sounds like he's willing to wait.

We're so used to seeing Teyana Taylor absolutely SLAY when she's busting a move ... except when she runs out of real estate, which is what led to a nasty-looking tumble off stage.

The crazy fall went down at PlayStation Theater in NYC where she was performing her set in the tour formerly known as the Later That Night tour (more on that in a bit). You see Teyana doing what she does best -- move her body -- when, outta nowhere, BAM ... she slips.

You can see her left foot lose grip ... and though it looked like an awkward fall (that right knee appears to bend like no knee should ever bend), Teyana quickly gets up and doesn't skip a beat. 

Unclear if hubby and NBA player Iman Shumpert was in the crowd during the tumble. 

It's interesting ... this was the last time Teyana performed in the Later That Night tour. As we reported ... Teyana hijacked the tour Jeremih was headlining and rebranded it the KTSE on Aisle VII tour.

LaDainian Tomlinson has ZERO sympathy for Broncos players who got wack haircuts this week ... 'cause back when he was a rookie -- he was hazed to the tune of a near $20,000 dinner check!!

We got the legendary Charger out at LAX when he told us the Denver hazing story doesn't even compare to what he went through as a first-year player in 2001.

"The late Junior Seau and the veterans hazed me by taking me to dinner and spending $18,000 of my money!" L.T. tells TMZ Sports.

Don't feel too bad ... Tomlinson not only went on to earn more than $56 MILLION in his career -- he tells us he "absolutely" repaid the favor to rookies when he was a vet!!

Shaunie O'Neal says life at the ultra-exclusive Crossroads School in L.A. will be a breeze for LeBron James Jr. ... because her son Shareef O'Neal educated the institute on how to deal with a celebrity student.

Shareef transferred into Crossroads after his sophomore year in high school, and Shaunie thinks all the media coverage he got will help Bronny, who as the son of LeBron James will probably get more.

But, it's not just the media ... Shaquille's ex-wife thinks Bronny will also benefit from the fact that the school is now more equipped on how to get superstar offspring ready for college.

"When Baron was there the rules like NCAA rules were so drastically different then they are now, and it was fortunate but unfortunate that they were learning that process with Shareef ... They hadn't had a student athlete on that level since Baron."

BTW -- O'Neal's youngest son Shaqir is also currently at Crossroads, and at 15 he's already 6'3" according to Shaunie.

Gonna be a fun couple of years in Santa Monica (that's the rich-ass neighborhood the school is in).

NHL star Alex Ovechkin is still livin' the dream -- on top of winning his first Stanley Cup ... he's now welcomed his first child to the world.

The Washington Caps' captain is a new dad after his wife, Nastya Ovechkina, gave birth to a son Saturday ... and his name is Sergei Aleksandrovich Ovechkin.

He's reportedly named after Alex's uncle, who died when he was 10.

Ovechkin's kid was born in South Florida, meaning he'll have both Russian and American citizenship.

18.08.2018....❤️спасибо тебе моя девочка за самый прекрасный день в жизни !!!@nastyashubskaya ❤️❤️❤️❤️❤️

A post shared by Alexander Ovechkin (@aleksandrovechkinofficial) on Aug 18, 2018 at 9:24am PDT

The Conn Smythe winner took to Instagram to post a pic holding his son's foot and thanking his wife, writing ... "Thank you my girl for the very best day of my life."

Congrats!!

Did you know Carson Palmer lived like Pablo freakin' Escobar during his time as QB of the Cardinals?!?!

It's true ... 'cause TMZ Sports has learned the ex-NFL superstar just sold his mansion now that he's retired -- and the place was EPIC!!

The palace -- located just north of Scottsdale in (fittingly) Paradise Valley -- was a whopping 6,785 square feet and had 6 bedrooms, 5.5 bathrooms, a pool AND A MOVIE THEATER!!

It coulda been all yours too ... but somebody just snatched it off the market for $2.9 MILLION -- according to David Khalaj from Pro Sports Realty.

Bummer for Carson to lose such a crib ... but he did make $300,000 on the deal -- sooo, all good, right??

Happy retirement!!

We spotted NY Yankees legend David Wells out in NYC -- and asked if he had any advice for Luis Severino, the Yankees ace who's been struggling recently. 

Wells told us he doesn't watch much baseball these days ... but did drop a few pearls of wisdom for the 24-year-old fireballer. 

"S**t happens when you struggle ... find a way out of it!" 

The clip is pretty great ... Wells talks locker room stories, golf and even gives props to our photog for dodging obstacles in the street. 

Good stuff ...
