Bling!

You're not seeing pink elephants ... that's just Justin Bieber's new grill.

Sources close to JB tell us he recently bought himself a new pink sapphire grill ... which ran him somewhere in the ballpark of $15k.

The mouthpiece comes courtesy of Gold Teeth God -- a jeweler based out of L.A. -- who we're told Justin flew out to Miami last week to do an impression of his chompers.

The grill is a combo of pink sapphire and rose gold, with 6 teeth covered on top and another 6 on the bottom. It comes with 6 carats of sapphire ... and took about 5 days to make.

We're told Justin has bought jewelry from GTG before, so going to him for the grill was a no-brainer. He seems to dig it, too.

All we can say ... love your grill, Biebs.

Sean Kingston is getting a raw deal from all the jewelers who've sued him for not paying for a bunch of chains and watches ... at least that's HIS story, and he's sticking to it.

Sean was at LAX flashing what he says is nearly $300k worth of ice and silver and gold -- so, naturally our guy had to ask why he's constantly got lawyers on his ass to pay for his bling. The singer/songwriter breaks down the giant conspiracy to take him down.

And Sean insists ... he ALWAYS pays. Eventually.

It's an interesting excuse explanation. Maybe not a good one, but still ...

Here's Seattle Mariners manager Scott Servais making good on a challenge to his players ... and making a case for coolest MLB manager around.

Servais told his guys that if they scored 10 or more runs against the Oakland A's he would reward them by sportin' a swagged out travel outfit -- complete with some of the players' chains.

The Mariners went out and won the game 11-1 ... and Scott proved he's a man of his word, donning some very swagged out neck decoration.

Migos' Quavo now has his own piece of bling based off one of the group's hit tracks, but unlike Offset ... he decided to big up the song, "Dat Way."

Quavo threw down $35k for his new rose gold chain and Napoleon pendant covered in over 300 diamonds at a total weight of 10 carats.

It was made by Atlanta's Icebox Diamonds & Watches, where owner Zahir Jooma tells us Quavo is a regular. Zahir says Quavo asked for Napoleon pointing "dat way" since it symbolized power and progress.

Quavo was already rockin' the new bling last weekend at Coachella.

Remember, Offset was at the festival, repping for "Bad and Boujee" with his raindrop chain.

La La Anthony is making a big statement in NYC -- going out without her wedding ring ... after separating from her husband, Carmelo Anthony.

Sources connected to La La tell us she hasn't worn the ring in more than a week -- since she moved out from the home she shared with the NBA star.

We broke the story, La La ain't happy with Melo after a woman came forward claiming to be 6 months pregnant with his kid.

So far, no divorce papers have been filed but sources tell us it's just a matter of time at this point.

Kid Rock doesn't kid around when it comes to locking down his longtime gf ... we got the first shots of the diamond ring he put on Audrey Berry when he popped the question.

Sources close to the couple confirm they got engaged earlier this year, but rumors started swirling when Audrey was seen rocking this ring on her left hand during Kid's fan cruise a couple weeks ago.

No question, Audrey looked totally charmed by her rock ... she couldn't stop smiling and staring at it.

Audrey and Kid have been linked together for nearly a decade. This will be his second marriage. He famously married Pamela Anderson in 2006.

Sam Hunt and his new wife, Hannah Lee Fowler, are doing that thing newlyweds do -- heading out for their honeymoon, and looks like she's getting a long one.

The Hunts were at Atlanta's Hartsfield-Jackson airport Monday with two giant suitcases, so we're guessing they've got more than a week planned. They were both sporting their rings, but no clear shot of Hannah's. Let's be honest ... no one cares what the guy's looks like.

No word where they're headed, but we're sure it'll be sickeningly beautiful wherever they land.

They got hitched Saturday in a small wedding, in celebdom anyway, only about 150 of their closest friends and family attended.

Lil Uzi Vert is officially the biggest Marilyn Manson fan ... unless you know of any others who spent six figures to make an iced out pendant in his likeness.

Uzi was rocking his newest piece at Coachella this weekend. The image of Manson rockin' Mickey Mouse ears is damn near priceless -- the chain and pendant together are made up of 16,000 diamonds totaling 155 carats.

Celeb jeweler Ben Baller delivered the goods to Uzi on Sunday, and IF & Co. Jewelers made it for $220k. We're told the labor alone cost $50,000.

Manson is the only person Uzi follows on IG, so his love for the rocker is deep ... and expensive.

Ex-NBA superstar Steve Francis called police "groupie motherf**kers" during his DWI arrest back in November ... and DARED cops to lock him up after they confiscated his gold chain.

Some jewelry "experts" in our office think the ring might be a Hamsa evil eye, and not an 'H' for Harry. The debate rages.

Meghan Markle stepped out in Toronto wearing a new ring on her finger and it's got Harry's initial all over it.

Harry was in town this week visiting his gf ahead of Easter. We don't know if he got her the new bling or not. It's not that flashy, by royal standards.

Harry officially announced he was dating the "Suits" actress in November. She recently joined him at a Caribbean wedding for one of his pals, so the ring ain't all that surprising.

Could be a warm-up to something bigger.

Mack Wilds' treasured '95 pendant is looking so shiny and new, 'cause that's what $35k worth of diamonds tend to do.

Mack's had the chain for a while -- The Ninety Five Percent is his company -- but he just added the major coat of quality rocks. Nothing but VS-1 and F colored diamonds (that's primo) covering the 14-carat yellow gold emblem. Jewelers David Bling and Will Da Boss did the flashy enhancements.

We're told Mack threw down the dough for the new piece because he's had a good year -- 2 TV shows, "Shots Fired" and "The Breaks," and his 2nd album, "After Hours," just dropped.

His company motto is "No such thing as 100% in life because if you ain't growing, you dying."

Mack's jewelry collection agrees.

The Chicago Cubs finally got their World Series bling Wednesday night -- complete with 214 diamonds, rubies, sapphires ... and a BILLY GOAT.

Boosie Badazz' $1 million jewelry stash was never jacked by cops -- it was just impounded and nobody bothered coming by to pick it up ... according to a Biloxi city officials.

Public Affairs Manager Vincent Creel tells TMZ ... cops found a suitcase full of gold jewelry and a stolen gun in the van they pulled over in connection with the scuffle between mall security and Boosie's crew on Sunday. We're told cops gave instructions on how to get all the property back ... but nobody followed them.

Boosie's crew says they were pepper sprayed by security and arrested by police after the mall incident, and the rapper was beyond pissed, claiming police stole his ice. Creel says that's untrue ... in fact, someone has claimed the van and jewelry.

Biloxi officials tell us they take offense to those challenging their "professionalism and integrity."

Also ... we're told the stolen gun has yet to be claimed.

Boosie's got another take on the whole situation, though ... claiming the jewelry only happened to show up once he and his lawyers put heat on the police.

Boosie Badazz is accusing cops of jacking $1 million worth of his jewelry after a security guard booted him and his family from a mall, and blasted them with pepper spray.

The rapper claims his crew was accosted by a mall cop in Biloxi who was acting racist, calling him "boy." Boosie says the guy unloaded the pepper spray on his pregnant niece .. and continued spraying his whole crew.

Boosie claims the jewelry heist happened when his van got pulled over after leaving the mall, and police arrested some of his entourage. He says cops are denying they have the loot, but Boosie's pissed and declaring "it's on" now.

Migos' most famous line just got the bling treatment.

Offset just dropped $100k on a ridiculously iced out chain in the shape of a raindrop. It's obviously inspired by their hit, "Bad & Boujee" ... which, for anyone sleeping out there, starts "raindrop, drop top."

Elliot Avianne of Avianne & Co Jewelers tells us the raindrop pendant is 32 karats which makes for a total of 65 karats when you add in the chain. Offset came up with the idea and wanted it ready in time for Quavo's bday this week -- he turned 26 on April 2.

The crazy part ... Elliot got the piece done in 48 hours, so ...

Yeah, Offset's diamonds a choker (glah) / Holdin' fire with no holster (bloaw).

Sean Kingston bought a $46k Rolex, but bounced the check to the jeweler and still owes almost half the bill ... according to a new lawsuit.

Norman Silverman Diamonds says the rapper paid $10k upfront and sent a check for $36k a few days later to have the Rollie shipped to one of his biz associates in June 2013. After the watch was mailed, though ... the jeweler says the check did not clear.

According to the docs obtained by TMZ, the jeweler was able to collect $15k more from Kingston in September 2013, but since then he's gone radio silent ... leaving an unpaid balance of $21,353.

It's been nearly 4 years, but time has not healed this Rolex wound. Silverman wants the rapper to pay up now and throw in extra dough for damages and lawyer fees.

Hate to say it, but Silverman might need to take a number.
