Solange Knowles is a couple huge diamonds short after a bead-throwing mishap in New Orleans Thursday night.

Knowles' wedding ring fell off her finger somewhere along St. Charles Avenue -- this according to a Facebook post from parade officials. Solange was riding a float in the Krewe of Muses parade when the ring went missing.

Law enforcement sources tell TMZ Solange has yet to file a report.

Krewe of Muses is offering an unspecified reward for the rock.

Solange and Alan Ferguson got married in November 2014.

Nothing brings a group of tough football players together like a bottle of California red ... just ask Jim Kelly -- who reunited with a bunch of his former Bills teammates in Napa Valley this week.

The QB hooked up with Bruce Smith, Thurman Thomas, Cornelius Bennett, Steve Tasker and Darryl Talley (and their wives) for a 25 year reunion from Super Bowl XXV.

TMZ Sports spoke with Thurman's wife Patti who told us, "These guys are obsessed with each other. It amazes me that after all these years they are still so close."

"They try to visit each other as much as possible. But this was definitely a special occasion with them all being together. This is a special group of guys. It was nice to be together for a few days before a couple of the guys have their commitments at the Super Bowl."

Mike Piazza's timepiece game just got stronger ... courtesy of a SWEET GIFT worth $25k from the CEO of a luxury watchmaker ... TMZ Sports has learned.

The gift giving went down in Miami at a party thrown by Swiss watchmaker Ulysse Nardin and luxury lifestyle magazine Haute Living ... and the soon-to-be Hall of Famer was in attendance.

Piazza -- who's a friend of U.N.'s CEO -- was given a Ulysse Nardin Midnight Express Special Edition watch -- 1 of only 100 in existence -- to celebrate his election into Cooperstown.

It's good to be one of the greatest baseball players of all time.

Kate del Castillo is now wanted for questioning by the Mexican government, and TMZ has learned the case involves tequila and alleged money laundering.

Kate -- who interviewed El Chapo while he was on the run -- is an investor in Tequila Honor, and our sources say the government wants to know if El Chapo secretly invested in the company and the money he put in was laundered.

The government wants to question Kate and if she returns to Mexico they could detain her for that purpose. Sources connected with Kate tell us, although she'd like to go back to Mexico to visit family, she will not return until the investigation is closed. She lives in L.A.

If you're a 'Sharknado' fan with access to a tow truck or flatbed ... that cool RV used to blow up the latest windstorm of flesh-eating great whites is up for grabs!

The Asylum, the production company responsible for the franchise, listed the battle worn ride from 'Sharknado 3' on Craigslist. Asylum's landlord gave them 24 hours to move it or lose it -- so, we're told it's going to the first person who can get it off their lot in Burbank, CA.

The reason it's so trashed has nothing to do with flying sharks, and everything to do with a transient who recently set fire to the thing. Hence, the steal of a price. Asylum thinks the engine's still salvageable though.

C'mon, Ian Ziering ... think of it as a cool DIY project!

Lil Wayne and George Washington co-star in a Super Bowl commercial this year -- but some people are taking issue, since it shows Wayne cooking for George ... who famously owned slaves.

The ad for Apartments.com features Jeff Goldblum and a gospel choir singing 'Jeffersons' theme "Moving On Up." Eventually you see George and Weezy (get the reference?) all chummy next to a rooftop barbecue grill.

The criticism? The ad is low-key racist due to Washington's history as a slaver, but Wayne's camp doesn't see it that way ... at all. A source very close to him says the commercial is "meant to be funny and silly and not the least bit offensive."

The source added it's supposed to be comedy, and "people need to calm down."

We've also reached out to Apartments.com, but no word back yet. Either way, their ad's getting way more attention now.

The owner of the Oakland Raiders tells TMZ Sports ... he does in fact own the domain LasVegasRaiders.com -- and has for years -- "just in case" the Silver and Black move to Sin City.

We spoke with Mark Davis who confirmed he personally bought the domain back in the '90s "in case the team ever wound up in Vegas."

"I think it's only $8 per year ... so, it's worth it in case we end up there."

When asked why he liked Vegas as a possible destination, Davis said -- "It's close to where we are now. It would be a close trip for our fans and there are a lot of sports fans who visit Vegas."

One other interesting thing ... Davis told us he believes the Raiders are the only NFL team that could "exist" out in Vegas.

So far, it seems Vegas could still be in the cards for the team -- especially with Las Vegas Sands honcho Sheldon Adelson gunning to build a $1 billion stadium on the UNLV campus.

Kanye West now has peace on all fronts after hashing things out with Wiz Khalifa.

Kanye says he and Wiz chatted on Monday and it was a "Great convo." He didn't reveal much more about their discussion ... other than to say it was "All positive."

We've learned the peace summit was two-pronged. Our sources tell us Wiz and 'Ye's convo went down Monday morning -- and a few hours later Kim Kardashian and Amber Rose spoke to each other ... then decided to have their meeting at Kris Jenner's house.

Ever since their feud exploded on Twitter last week, Wiz has been blasting Yeezy almost every night during his South American tour -- but in an interview with Bootleg Kev on Tampa's Wild 94.1 ... Wiz said it's all squashed.

Meek Mill dropped $68,000 over the weekend on a Rolex ... which might become an antique before he's able to wear it, because they don't allow fancy watches in the slammer.

Meek bought the piece from Joe the Jeweler aka "Shyne." It's a custom-made Presidential Rolex with 23 carats of white round diamonds.

Here's the problem ... Meek has a hearing Friday in his probation violation case. You'll recall he left the state of Pennsylvania without permission. There are also allegations he tried to cheat a drug test. The judge could send Meek to prison for the violation.

Meek might need a fortified safety deposit box for his collection.

Peter Thomas isn't in the clear for an alleged bar brawl in his Charlotte sports bar -- investigators want to have a sit down with him to get his side of the story.

Cops issued a criminal summons on Monday for the "Real Housewives of Atlanta" star. As we first reported, Brandon Link claimed Peter attacked him during a business meeting at Sports One, which Peter and Cynthia Bailey own.

Link claims Peter threw him into a table ... but Peter claims Brandon was belligerent and only injured himself by slipping on ice outside the bar. Cops responded, and made no arrests but they continue to investigate.

Scary moment for the Denver Broncos moments ago ... when a team bus clipped a member of its police escort ... but miraculously, no one was harmed ... TMZ Sports has learned.

Blake Griffin -- along with at least one teammate and the team's equipment assistant -- had been drinking in the hours leading up to the fight in Toronto ... multiple witnesses tell TMZ Sports.

According to several witnesses, Griffin and the equipment manager were seen fighting outside of Sotto Sotto restaurant in Toronto on January 23rd.

Before the fight, witnesses say Griffin's crew was spotted at Coco Lezzone -- across the street from Sotto Sotto -- where the group ordered a couple rounds of drinks.

We're told the guys left Coco and went to Sotto ... where they spent roughly 2 hours before witnesses saw the men fighting in the street.

Clippers president Doc Rivers has said he does NOT believe alcohol was a factor -- though he did point out the guys are old enough to drink ... and drinking alone is not a crime.

We spoke with a rep for the Toronto PD who tells us there is no record of an incident involving Griffin -- however, "It is highly possible that police were in the area at the time and may have dropped in. In Toronto it is very likely and possible."

As we previously reported, cops say there is no investigation into Griffin -- and won't be unless someone files a formal complaint, which has not happened.

When reached for comment, a rep for Sotto Sotto had no comment.

We also spoke with the Clippers and reached out to Blake's rep -- but they have all declined comment as well.

Here's video of the moment Def Leppard had to think their cruise was cursed -- when the host broke the news one of the rockers on board had died.

The deceased was Jimmy Bain, the famed bassist for classic metal groups Dio and Rainbow. He was on the cruise to perform with his new group, Last in Line ... but they never took the stage.

Bain's rumored to have died from pneumonia, but his official cause of death has not been determined.

The whole cruise was filled with mishaps -- including Def Leppard singer Joe Elliott losing his voice! We got Brian Forsythe from the band Kix, also on the cruise, and he explained how the rock show turned into a memorial at sea.

Police in Georgia want to talk to Future to see if he can help them find whoever killed his former bodyguard.

Michael Phillips was shot and killed Monday at his home in Jonesboro, Georgia ... outside Atlanta. Cops say they don't have any suspects in custody yet, but they have several leads. They're interested in talking to all of Phillips' friends, including Future, to see if they have info that could narrow the search for the gunman.

Investigators tell us they don't think it was gang-related, and Phillips wasn't shot in a high crime area.

Freebandz paid his respects on Twitter, after the news broke:

Harry Styles walked away from his lunch with Rande Gerber with the greatest doggy bag in history ... 20 cases of really good tequila!

Turns out it was an awesome pre-birthday gift for Harry, who turns 22 February 1st. The tequila is Casamigos -- the brand Rande owns with best bud George Clooney.

We're told Harry will make good use of the booze ... he's throwing himself a birthday shindig this weekend at an L.A. estate.

Mariah Carey has a brand new piece of jewelry -- a massive engagement ring -- 'cause her billionaire boyfriend James Packer just popped the question ... and Mariah said YESSSSS!!!!

It all went down in NYC -- where Packer secretly rounded up a bunch of Mariah's close friends for a private dinner at Eleven Madison Park ... so he could get down on one knee and propose in front of the most special people in her life.

Carey and Packer have only been dating since June 2015 -- but their relationship heated up real quick ... with the two famously spending several consecutive weeks together on his yacht over the summer.

The relationship blossomed months after Carey split from husband numero dos, Nick Cannon ... the father of her two children.

Carey had been married once before Cannon to music mogul Tommy Mottola ... so this will be her 3rd marriage.

As for Packer, the 48-year-old has also been married twice before -- and has 3 children of his own ... so, this is kind of like a celebrity 'Brady Bunch' situation ... with a lot more money.

Packer is Australia's 4th richest man -- thanks to a combination of family money and success in real estate, casinos and entertainment.

As for the wedding, no word on when it's set to go down ... but at the rate these two are moving, it will probably happen in 2016.
