Bling!

Sean Kingston just picked up another L ... and it wasn't cheap.

The rapper's been ordered to pay $301,500 to NYC jeweler Aqua Master who sued him over 9 pieces of jewelry but was never paid. The items included 2 diamond necklaces, a few gold chains, a ring and 2 watches.

Making matters worse, Aqua says Sean flaunted the pieces on his IG.

TMZ broke the story ... Aqua sued Sean back in 2016, but the rapper never responded to the lawsuit, so the judge issued a default judgment. Aqua says Sean made a halfhearted attempt to pay ... sending 2 checks. But they later bounced.

Stop us if you've heard this one before ...

Floyd Mayweather hit up a crazy expensive restaurant sporting a crazy expensive watch -- and couldn't wait to show off his jewelry on camera!

This time, Floyd -- surrounded by his TMT bodyguards -- was in the mood for fancy Chinese food at Mr Chow in Bev Hills ... and on the way out it, he let his blinged-out wrist do the talking.

As we've previously reported, Mayweather has an insane watch collection -- including a $2 MILLION diamond-covered timepiece ... which he showed off back in 2016.

He also bought a $1.1 million diamond-covered Hublot watch during a shopping spree at a mall in Dubai back in 2015. It's one of the most expensive watches in the world.

No word if the watch he rocked on Tuesday is brand new or an old favorite -- but one thing's for sure ... it's expensive.

Quavo doesn't have a thing to worry about when it comes to an arrest in the 1 OAK nightclub fight in NYC, because video shows he didn't touch the alleged victim ... according to Quavo's attorney.

Drew Findling tells TMZ ... he's seen surveillance video from inside 1 OAK on Grammy night, and it shows Quavo did NOT "come within 3 feet" of Eric the Jeweler. He says the video does show an altercation, but Quavo wasn't involved.

TMZ broke the story ... Eric says 2 men jumped him in the club, and possibly jacked his $30k chain. He claims Quavo was one of the attackers. Law enforcement sources told us NYPD was preparing to arrest the Migos rapper for the fight.

That's news to Findling who says, based on the video, his client is in the clear.

Quavo is about to get a new wrist accessory -- handcuffs -- law enforcement sources tell TMZ.

Our sources tell TMZ ... NYPD detectives have gotten in contact with the Migos rapper's attorney, Drew Findling, informing him they have enough evidence to arrest Quavo. We're told an arrest warrant hasn't been issued but it's only a matter of time.

Findling tells us his client's an innocent man and hopes for the sake of the NYPD and the Manhattan DA's office, they don't embarrass themselves by hooking his client up and prosecuting him.

TMZ broke the story ... Quavo allegedly beat the crap out of Eric the Jeweler when he tried to collect on Offset's $10k tab. Sources say Quavo and another man jumped Eric and jacked his $30k chain.

Lil Uzi Vert didn't take home a Grammy this year ... but he dominated the bling game by rolling into the show with more than a quarter mil around his neck.

The rapper -- who was nominated for Best New Artist, but lost to Alessia Cara -- went to the Grammys donning a custom 60-carat upside-down cross wrapped in a gold and diamond vine ... hanging from an 80-carat diamond chain.

We're told Lil Uzi reached out to celeb jeweler, Elliot Avianne of Avianne & Co Jewelers, 3 months ago to get it made ... and dropped about $350k on the piece.

We're told it was finished just 3 hours before the show and hand-delivered to him -- just in time for him to walk the red carpet ... and give this hilariously awkward interview.

Rapper NBA YoungBoy's setting the bar high when it comes to friendship and loyalty ... immortalizing Young Thug with this SICK pendant.

We're told YoungBoy reached out to Joe the Jeweler, aka "Shyne," in Philly and requested the custom pendant ... encrusted with 95 carat VVS diamonds worth around $150k. Shyne needed about 2 months to complete the masterpiece, which btw is a replica of an actual YT pic.

So why Young Thug? YoungBoy considers him a great friend and an idol. It's that simple.

Here's hoping he doesn't need to have JoJo Capone on standby.

We all know what Bill Belichick's wearing on Super Bowl Sunday (hoodie) -- but his girlfriend Linda Holliday is going with A LOT more flair ... with a custom crystal outfit, and TMZ Sports has the pics!

Linda hit up Leah Miller at Bella Artistry who makes custom Swarovski crystal fashion items for a TON of athletes and their significant others ... and ordered up some fresh gear for SBLII.

Holliday will be wearing a special blazer with her BF's last name spelled out across the back and his initials on the arm. We're told the blazer has 3,500 crystals that were all hand-placed, one-by-one.

She also got a blinged out purse complete with 1,200 Swarovski crystals!

Bill's boss is a fan of Leah's work as well -- Robert Kraft is getting a special crystalized pair of Nikes ... customized for the Pats owner himself with 13,000 crystals!!!

Now all they need is another ring to match!

Quavo's alleged beatdown of a famous jeweler was all over $10,000 ... but it wasn't Quavo's debt to pay, TMZ has learned.

Sources close to Eric the Jeweler -- who cranks out bling for 50 Cent, Snoop Dogg and many more hip-hop stars -- tell us Offset is the member of Migos who owes the $10k. Law enforcement sources confirm Eric said exactly that when he reported the fight and robbery of his $30k chain.

We're told Eric reached out to Offset multiple times about settling the debt, but was given the run-around. Then, when he bumped into Quavo early Monday morning at 1Oak, that's allegedly when the fight broke out. The jeweler suffered a swollen cheek, bloody nose and a bump on his head.

TMZ broke the story ... NYPD wants to talk to all the members of Migos and their manager. According to police docs ... Eric was jumped by Quavo and another man.

Still no word from reps for Migos.

Lil Pump is super hot these days and he knows it ... because he ain't signing no recording contract for anything less than $15 mil.

We got Pump leaving Avianne and Co. Jewelers Friday night in the Big Apple, where he says he dropped a quarter mil on bling.

The 17-year-old rapper reportedly got out of his deal with Warner Bros. Records because it was never certified by a court ... something that's required when minors are involved.

Pump's been getting offers, which makes sense. He's got several hit songs, including "Gucci Gang."

He better sign a new deal fast ... he says he just bought a Rolls-Royce and is spending like crazy.

Steve-O just might've pulled of the craziest stunt of his life ... he got engaged to his girlfriend, Lux Wright!!!

Steve-O popped the question Saturday night onstage at the end of a comedy special he was filming in Denver with his "Jackass" buddies and family in the audience, and when we got him Sunday at LAX he gave us a firsthand look at the ring he put on Lux.

If he sounds like a new man rather than the guy known for putting a black widow spider in his mouth for shits and giggles, just wait till you hear his dream wedding plans ...

Sometimes it pays to be a Lil Yachty mega-fan -- just ask this 17-year-old who got showered with gifts from the rapper ... as a late Christmas gift.

Yachty personally delivered a bundle of goodies to Danielle Combs (no Diddy relation) in Atlanta last week after promising some "rare" swag to her and another fan.

We're told he hooked her up with a bunch of gear from the Sailing Team -- Yachty's rap collective -- which included some custom jewelry. Danielle's name was engraved on the back of an 18-carat yellow gold necklace from Icebox Diamonds & Watches ... with 184 diamonds and a $10k price tag.

Our Yachty sources say he's purchased nearly 25 Sailing Team necklaces from the ATL-based jeweler.

As for why Danielle was a lucky winner, we're guessing it had something to do with her dope artwork of Yachty. Float on, kid.

Turns out Queen Elizabeth ain't so down with her crown, after all.

QE2 caused a bit of an uproar in the U.K. during her first sit-down interview with the BBC ... because she damn near bounced her crown. You gotta see her attempt to lift the crown, only to quickly drop it, saying ... "It weighs a ton."

The Queen makes it seem like she hasn't seen her crown in years and, in fact, couldn't tell the front from the back. Can ya blame HRH?

Family jewels can be confusing ... and heavy.

Lil Pump's spreading his newfound wealth around ... hooking up members of his team with some fresh bling for the new year.

The 17-year-old rapper ordered 8 iced-out chains that say "Tha Lights Global" -- the name of his label -- with pendants in all different sizes ... from 10 to 30 carats. We're told they cost $350,000 overall.

Pump hit up Elliot Avianne of Avianne & Co Jewelers in NYC 2 months ago to have the chains made, but he tells us the "Gucci Gang" rapper still hasn't come to pick them up. It's also unclear who gets what piece.

As we reported last month ... Lil Pump's contract with Warner Bros. had him on a path to millionaire status soon, but he's reportedly had that contract voided and now is entertaining other offers.

Flex like ouu!!!

Kim Kardashian's grillin' like it's summertime again, and looking like she's dipping back into her old flashy lifestyle.

Kim got herself some new mouth bling after swearing off flaunting jewelry, post Paris robbery. She rocked it proudly for a selfie alongside model and DJ Sita Abellan.

The gold mouthpiece, bearing Kim's name, might not be as noticeable as a diamond ring ... but the sucker shines when she smiles.

As we reported, she's not keeping her jewelry collection at the new Hidden Hills mansion for security reasons -- but based on her shiny new grill, Kim's still down to get flossy every now and then.

Lucy Hale is out at least $15,000, and probably even more, after her home was hit by burglars ... TMZ has learned.

Law enforcement sources tell us the "Pretty Little Liars" actress' San Fernando Valley home was broken into and burglarized very early Friday morning. We're told the perp smashed through one of her front windows and stole jewelry and purses currently valued in excess of $15k -- but that number is likely to go up once full inventory is taken.

Lucy was not home at the time of the break-in. We're also told her alarm was on, and all signs point to this being a random hit ... not a case of burglars targeting a specific celeb.

That jibes with the string of burglaries over the last year -- which, as we've told you, cops believe are being carried out by professionals looking for nice houses. Celebs just seem to be casualties getting hit along the way.

Kyle Richards, Yasiel Puig, Mariah Carey, Jason Derulo and Scott Disick ... ya know what they have in common? They've all been hit by burglars, and now we know cops have a take on who's doing it.

Law enforcement sources tell us ... most of the celebs have been hit by professional burglars, who know the weak points of a home and how to penetrate them. For example, a number of the break-ins have been through second floor balcony windows, accessed by a ladder. The reason ... many homeowners don't put alarms on second floor doors and windows.

Cops also say there seems to have been a migration ... burglars are now hitting the San Fernando Valley more than the Hollywood area, where the first wave of break-ins occurred. The LAPD is investigating 23 celebrity burglary cases ... of those, 19 occurred in the Valley.

In case you're interested, the area of the Valley where many of these celebs live is pretty secluded, so it's easy to hit a home, drive to a freeway and get lost among the zillion drivers.

Now the big question ... Is this like another Bling Ring? Cops tell us the answer is no. There are various, sophisticated groups of burglars hitting posh areas of L.A. Police say there have also been an incredible number of non-celebrity hits. These burglars are looking for nice houses with nice contents ... they're not looking for famous victims.

Still ... hard to imagine a few of these hits were planned after the celeb homeowners posted their out-of-town pics on social media.
