Jay Z & Solange Fight

Jay Z showed up to Solange's wedding Sunday in New Orleans breaking a cardinal rule ... but in this case there's an exception.

Hova and Beyonce arrived hours before the nuptials and Jay dressed to the nines in a fancy white tux.

Wearing white to someone else's wedding is normally frowned upon ... the whole upstaging the bride thing. But when you look at the photos it appears the ceremony has an all-white theme.

Mathew Knowles thinks the Beyonce/Jay Z divorce rumors ... and even the infamous Solange elevator fight video ... were both carefully orchestrated by the duo to drive up ticket sales.

Beyonce's dad was on KRBE in Houston where he theorized all the recent turmoil around the couple was simply a "Jedi mind trick" they orchestrated as a way to make their summer tour super popular.

He explained, "All I know is the Jedi mind trick. Everyone’s talking about it. Ticket sales went up. Solange’s album sales went up 200%!"

Get ready to interpret ... because Beyonce now obtusely reveals what went down in that elevator ... and one interpretation goes directly to her marriage.

Beyonce dropped a remix for her song "Flawless" with Nicki Minaj Saturday night ... and early in the track says, "We escalate, up in this bitch like elevators ... of course sometime s**t goes down when it's a billion dollars on the elevator."

So how's this for a theory. Multiple reports estimate Beyonce and Jay Z's worth between $900 million and 1 billion. So when she says "of course sometimes s**t goes down when it's a billion dollars on the elevator" ... could that mean there's a billion dollars on the line and they were arguing over something related to the heart of the marriage?

Just a theory.

Beyonce and Solange's reunion in New Orleans really was a family affair ... TMZ has learned Jay Z also joined in on the fun.

Bey, Solo and Hova all hit up New Orleans hot spot Cafe Amelie for more than 2 hours Saturday ... according to multiple sources -- and the fam came with a MASSIVE security detail and 3 black SUV's waiting nearby.

We're told a team of bodyguards waited outside making sure no one could get a clear shot of the threesome hanging out.

The person who snapped this pic says when it came time to leave, Jay and Beyonce darted in separate directions to the car ... forcing the photog to choose one. The queen won.

Beyonce later posted a family picture from the lunch ... Jay Z, Solange, and all.

Beyonce is putting it out there as clearly as she can ... she's a member of one big happy family.

Beyonce and Solange reunited in New Orleans Saturday ... Bey posted a pic of the two embracing on Instagram -- and captioned the date and location to show it was legit.

No sign of Jay Z.

Until 4 hours later ... when she posted the trailer for her upcoming collab with Hova and a ton of celebs called "Run."

They are indeed ... just like us.

The catalyst for the Solange/Jay Z elevator fight has been a mystery ... until now. "Saturday Night Live" spilled the beans ... an errant spider.

It's pretty funny ... especially Maya Rudolph who plays an epic Beyonce.

Jay Z and Solange are finally addressing the infamous elevator fight video ... saying BOTH sides are to blame for the violence that unfolded.

Jay Z, Solange, and Beyonce released the joint statement moments ago, saying, "Jay and Solange each assume their share of responsibility for what has occurred. They both acknowledge their role in this private matter that has played out in the public. They both have apologized to each other and we have moved forward as a united family."

The statement continues, "The reports of Solange being intoxicated or displaying erratic behavior throughout that evening are simply false. At the end of the day families have problems and we're no different."

"We love each other and above all we are family. We've put this behind us and hope everyone else will do the same."

The statement still doesn't explain what caused the fight, but Jay and Solange say they have worked through it.

Days after purging all Beyonce photos from her Instagram page (except for one), Solange posted a childhood photo of the two as part of Throwback Thursday.

Beyonce started the Instagram reconciliation trend on Wednesday, when she posted four photos of herself with Solange ... three of them caption-free.

The Internet continues to search through social media to find some meaning behind the Jay Z/Solange elevator fight ... and Beyonce's non-reaction to the whole thing ... so perhaps this means the two are trying to bury the hatchet.

7:10 AM PT -- Solange's rep says she wasn't in NYC. However, we were told by Mr. Flawless himself that he personally waited on Jay Z and Solange ... and was specific as to how long they were there and where they were looking inside the store.

We also spoke with a famous NYC DJ who happened to be outside the store, and also insists he saw Jay Z and Solange come out of the store, get into a Mercedes-Benz G Wagon and drive off.

Jay Z and Solange Knowles went looking for jewelry together Tuesday afternoon at a high-end NYC jewelry store ... TMZ has learned.

Our sources connected with the store say Jay and Solange were in Mr. Flawless, where they were looking for women's jewelry for around 20 minutes.

We're told the pair showed no signs of strife, and looked at gems with Mr. Flawless himself. They looked, but tried nothing on. They left the store without buying anything.

Jay and Solange didn't talk much inside the store ... they pretty much just browsed quietly.

If a picture says a thousand words, what do four pictures say?

In the first "response" of any kind since the blowout fight between Solange and Jay Z, Beyonce posted four photos of her with her sister to her Instagram page early Wednesday morning.

Only one of the photos was captioned and it merely said, "good morning."

It's curious ... since Beyonce merely stood by and watched Solange go ballistic on Jay Z. Is she saying she's taking Solange's side in all this? Is she saying she supports her sister despite her being completely in the wrong?

The Internet thinks it has solved the mystery of the Solange Knowles/Jay Z elevator fight, but TMZ has learned the tweet is a fraud.

Shortly after TMZ posted the insane video of Solange losing it -- a photo of a tweet emerged in which Solange accuses Jay Z of hitting Beyonce ... and the image was forwarded over and over again yesterday.

But the tweet in question was never really posted on Solange's Twitter feed, and never even existed -- IT'S A TOTAL FAKE. Solange's rep tells TMZ, "I can confirm that Solange did not tweet that; that is not a real tweet."

But as far as theories go ... it's worth noting that Solange has deleted all Instagram photos with Beyonce in them ... except for one.

The mystery lives on ...

The women of "The Talk" are just like everyone else ... they could not stop talking about TMZ's video of Solange attacking Jay Z ... and Sharon Osbourne finds the fight awesome and comforting.

Our photog caught up with Sharon, Julie Chen, Aisha Tyler and Sara Gilbert (Sheryl Underwood had already run off) Monday night in NYC.

Chen describes the situation as "shady," but Osbourne says the brawl gives her a connection to the Z family.

And check out Sharon on "Watch What Happens Live," as she described crapping herself during an introduction to one of "The Talk" girls.

Jay Z and Beyonce are sitting courtside TOGETHER at the Brooklyn Nets playoff game in NYC tonight ... clearly sending a message they're still on the same team after the big elevator fight with B's sister.

The couple didn't get to their seats until the 2nd quarter. Once they sat down, they were smiling and acting like their usual couply selves ... and even chatted it up with LeBron James like nothing was wrong.

We broke the story earlier today ... B's sister Solange went bersek on Jay in a hotel elevator on May 4th ... kicking and punching him like crazy while B stood by and watched.

Beyonce's sister should never have ever come CLOSE to attacking Jay Z in that hotel elevator ... because the bodyguard could have prevented the attack ... so says a guy who would know, Ken Shamrock.

The former UFC champ now specializes in private security for high-profile people -- and he tells TMZ Sports the guy who was with Jay that night simply FAILED at his job.

"It's pretty clear that something went off [between Jay Z and Solange] before the fight," Shamrock says.

"The bodyguard should never have put them on the elevator together. You're waiting for a time bomb to go off. And when it does, you're stuck."

Shamrock -- who's been working for Pro-tect Global for more than a year -- says the bodyguard also erred by turning his back on Jay.

"Rather than getting in between Jay and Solange, he was pressing the elevator buttons. It seemed to me he didn't know what his job was."

Ken says he knows the guy was in a tough situation and says it's easy to judge from afar -- but the bottom line is ... Jay Z got attacked -- and it didn't have to happen that way.

Jay Z found himself in a hand-to-hand combat sitch when Beyonce's sis, Solange Knowles exploded on him in an elevator -- all while Bey stood by like nothing at all was happening.

It's totally insane video of two sisters -- one crazed, one calm -- and one dude on the defensive.
