Bling!

Tekashi69 is going where no one's seemingly gone before when it comes to the chain game -- not only did he spend $95k on some new bling, but he added human hair to it!

The NYC rapper just threw down for a "My Little Pony" chain covered in VVS diamonds. The pendant alone cost $45k, while the chain was $50k, but the real eye-catcher is the mane ... which came from Tekashi's own colorful mop. Tekashi even had his hairdresser style it.

The owners of SHOP GLD in Miami tell us he ordered it a few weeks ago, but called them Tuesday saying he needed it for the new music video he's shooting with Nicki Minaj.

A limited batch of a smaller version of the chain will be available for fans, but we're guessing those will NOT include 6ix9ine's hair.

Karlie Redd dropped a new single Wednesday ... but that was quickly forgotten when her BF popped the question.

Karlie was hosting a party for her new single, "Ferrari Karlie," at Atlanta club Buckethead Loft when her now soon-to-be husband got down on bended knee and proposed. The pair has only been dating for few months -- he's her first relationship since she split with Grammy-nominated producer Sean Garrett.

There's not a whole lot of info available about Redd's new man ... but his name is apparently Mo, and he goes by Arkansas Mo on Instagram.

Karlie seemed a little more interested in the box the ring came in at first. It's pretty cool ... it displayed a bunch of pictures on an LED screen when she opened it. Her ring ain't too shabby either.

Chloe Kim tore up PyeongChang's icy half pipes for the 2018 Olympics, and now she's iced out again for the ESPYs ... rocking a new chain that's worth its weight in gold.

The U.S. Olympic gold medalist recently hit up celeb jeweler Ben Baller for some new bling to wear to the sports award show ... where she's got 3 nominations, including Best Female Athlete.

Ben whipped up something special for Chloe -- an 18k gold diamond Cuban choker, with 24 carats in diamonds and weighing 300 grams in gold. Oh, and we're told it's valued at $40,000.

Fun Fact: Chloe Kim and Tom are among the athletes with the most nominations at the ESPYs on Wednesday night.

As far as Best Female Athlete is concerned -- she's up against Sylvia Fowles (WNBA player) and Julie Ertz (soccer).

Justin Bieber and Hailey Baldwin have baggage ... but only literally.

Justin was rolling on the streets of NYC with his fiancee, proudly displaying the ring she bought for him as a sign of love.

The 2 were leaving Hailey's apartment for a weekend trip to Miami.

In case there was any doubt about their relationship ... Justin posted this pic of the 2 of them making out at David Grutman's house and they were later seen at Komodo restaurant.

Antonio Brown got himself one helluva birthday present this year ... copping an insane diamond chain made with A KILO OF GOLD ... and it's got an awesome meaning behind it.

TMZ Sports has learned ... the Steelers superstar hit up Gabriel the Jeweler -- the go-to guy for pretty much every NFLer -- for the piece featuring his logo made of 100 handpicked VS2 diamonds.

But if you look closely ... AB's fiancee and children's names are featured along the outside of the plate ... a special request Brown made to show love for his family.

Gabe tells us Brown -- whose birthday was July 10 -- was totally stoked with the results and has been rockin' it everywhere.

And, we know what you're wondering ... we're told the piece is worth around $200K!!

Justin Bieber wasn't traveling light when he took off for the Bahamas to pop the question to Hailey Baldwin ... he had a huge and pricey rock on him!

We spoke with Jack Solow -- the owner of Solow & Co. -- about the backstory of Hailey's engagement ring. He tells us he originally met JB through his manager Scooter Braun, a close family friend of his, and Bieber reached out to him a few weeks ago about buying a ring.

We're told he decided on a large, elongated oval-shaped diamond between 6 to 10 carats ... and Jack met Justin at his hotel in NYC to deliver it right before Bieber and Hailey left for the Bahamas.

Solow wouldn't spill the beans on the final price tag, but sources tell us it was around half a mil.

TMZ broke the story ... Justin proposed to Hailey Saturday night at their resort in front of the other guests, weeks after getting the blessing from her father.

She said yes.

YG's facing a felony robbery charge for allegedly yanking a dude's chain off his neck and taking off with the diamond-laced pendant ... and we're told there's video evidence too.

The rapper was in a Vegas court Thursday after a warrant was issued for his arrest and he turned himself in. YG was hit with felony robbery and he was released after posting $20k bail.

Vegas police tell us ... the incident went down in late May at the Cosmopolitan around 4 AM, after a man approached YG and asked for a pic but was turned away by his crew. We're told the guy told YG he's not a real celeb ... and casino's surveillance footage shows YG retaliating by yanking a chain off his neck.

We're told the chain fell to the ground, and YG is then seen on video picking up the necklace pendant -- valued somewhere between $3,000 and $9,000 -- before taking off.

We broke the story ... the alleged victim is also suing YG, claiming he had his goons beat him up before he snatched his jewelry. The guy wants at least $250k.

LeSean McCoy called police on Delicia Cordon in July 2017 after an argument over jewelry -- with the NFL star claiming she refused to return several high-end items she had borrowed.

It's all in police reports obtained by TMZ Sports ... which show cops responded to at least 3 incidents at their Georgia home over the past year.

But the most interesting incident took place on July 3, 2017 -- when the NFL star called the Milton Police Dept. to the home after a "domestic dispute" with Cordon.

When cops arrived, they saw McCoy standing in front of a large mound of D's clothes -- and he explained that they had been having issues and had broken up after she accused him of cheating on her.

Then McCoy brought up the issue of jewelry. Here's the quote from the police incident report.

"He went on to advise us that jewelers often times loan them high end jewelry items to wear for events. He stated that Cordon had some of these jewelry items and had not returned them."

"He stated that he has asked her multiple times for them but she has not yet returned them."

According to the police report, McCoy expressed serious concern that Cordon might make false accusations about him.

"He stated that he was trying to be very careful about being around her given the climate of domestic abuse in his profession."

Cops eventually spoke to Cordon. At the time, neither party made any allegations of physical abuse.

The case could be relevant since Cordon claims the assailant who broke into her home and pistol whipped her on July 10, 2018 demanded specific items of jewelry. Cordon told police she believed McCoy was behind the attack.

Justin Bieber and Hailey Baldwin are making sure her engagement ring doesn't slip off her finger because one of their first stops after getting back to NYC was at a jeweler.

The Biebs and Baldwin looked super chill and blissed out Tuesday evening as they waited for Hailey's ring to get resized inside Pristine Jewelers. Gotta say ... Justin's acing the fiance thing so far -- he gave Baldwin a shoulder massage while they were waiting.

She seemed reluctant to even briefly remove the ring. Still no word on the size or cost of her ring -- not that it matters. Hailey and Justin haven't stopped glowing since he popped the question this past weekend in the Bahamas.

We spoke with Avi and Ofir from Prestine who tells us JB also got a white gold ring of his own and picked up a white diamond encrusted Patek Philippe watch.

Justin Bieber got challenged to a dance off by some little kid and the Biebs happily responded ... with his new fiancée, Hailey Baldwin, front and center watching it all go down.

Justin and Hailey kept celebrating their engagement Sunday with a bunch of locals at Nipper's Beach Bar & Grill in the Bahamas. They had already danced their little hearts out on the beach ... but kicked things up a notch with a huge crowd.

Look closely ... Hailey's wearing her massive rock, which she adjusts while holding a drink. Justin's so pumped up after accepting the dance challenge he gets the entire crowd amped up too.

Justin Bieber appears to have spared no expense for Hailey Baldwin's engagement ring ... 'cause that thing is HUGE.

The newly engaged couple was seen hanging out at Nippers Bar & Grill in the Bahamas the day after he proposed to her Saturday night, and she was flashing her new hardware.

Hailey's wearing a fat diamond ring on THAT finger in the open, and we gotta say ... it looks like a hell of a rock. Hard to say exactly how big it is, but there's no question the ring is sizable. They danced their hearts out on the beach in celebration ... so it'd seem she digs it.

We broke the story ... Justin got on bended knee for Hailey in front of guests at the resort they're staying at while vacationing in the Bahamas. Cameras were forbidden during the special moment ... for which, of course, she said yes.

Selena Gomez, meanwhile, doesn't seem to have a care in the world about the news. She's living it up in New York ... on a boat ... laying out in the sun and whatnot.

Porsha Williams tried playing it coy when our camera guy straight-up wanted to know if she and her BF were shopping for engagement rings ... keyword: tried. 'Cause, all signs pointed to them hunting for a rock.

We got the 'Real Housewives of Atlanta' star and her boo after she met with Richie Rich from the Leon Diamond jewelry store in NYC and we had to ask ... was she looking at engagement rings? It's interesting ... Porsha's kept her relationship on the super DL for some time now and only made subtle hints she's in a relationship.

Just a few days ago, reports surfaced outing Porsha's new man as Atlanta businessman Dennis McKinley. She's also been ending her Instagram captions with #DM. And, that's the same guy we saw her holding hands with as she left the jewelry joint.

Where there's smoke ...

Katharine McPhee and David Foster are back in the U.S. after their European vacation and made an interesting first stop after their trip.

The couple -- dressed pretty casually -- was spotted in Tribeca, but reportedly made their way to a jeweler in Midtown Thursday, a few days after getting engaged.

Foster popped the question in Anacapri, Italy and Katharine confirmed the engagement by posting a text exchange where someone described her ring as "beautiful and classic." We also have a photo of her showing it off at dinner earlier this week.

She was wearing a ring on her ring finger Thursday afternoon, so it's possible she was getting it resized ... or maybe they were shopping for Foster.

50 Cent said Floyd Mayweather is a FOOL for snatching up an $18 MILLION diamond watch -- but Paris Hilton tells TMZ Sports ... Fiddy is wrong, she actually likes it!!

"It looks like a watch that I have actually," Paris said at LAX.

Floyd claims he picked up the famous "Billionaire Watch" from a jeweler in Japan -- a watch that contains 239 huge diamonds!!!

50 Cent clowned Floyd for the purchase -- saying, "Man they done found the 1 fool in the world,dumb enough to buy that watch. LOL get the strap."

As for Paris, she defended Mayweather's spending habits, saying -- "It's a lot ... but I think he works very hard, he works for his money and he can buy whatever he wants!"

Forget your Sanyo ... Floyd Mayweather says he just bought a brand new diamond watch -- WITH AN $18 MILLION PRICE TAG!!

"This my new timepiece, it's called 'The Billionaire Watch,'" Floyd says ... "If you don't know about it, google Billionaire Watch."

The watch is super famous -- made by Jacob & Co. back in 2015, it features 239 emerald-cut baguette diamond stones, each weighing up to 3 carats.

Jacob & Co. describes the watch as a unique piece that "truly epitomizes the brand’s passion for breaking boundaries."

"As the tourbillon caliber brings dynamism to its bejeweled enclosure, or the ballet of light of 260 carats of diamonds illuminates its exquisitely revealed heartbeat."

"The Billionaire is a dazzling representation of the courageous and rebellious Jacob & Co. spirit."

Floyd says he bought the watch from a Japanese jeweler named Tadashi Fukushima -- and says he'll never buy any jewelry from anyone else ever again.

Khloe Kardashian's flashing a massive rock on her left ring finger which might have ya thinking she's engaged to Tristan Thompson ... but don't go buying a gift yet.

Khloe and Tristan had dinner Sunday night at BOA Steakhouse on the Sunset Strip ... and from the look of things, it wasn't the most exciting date night. Khloe seemed to be giving Tristan serious side-eye while he looks at something other than her -- maybe his phone or the menu.

But the bling on her hand was a definite bright spot. Khloe's dressed up that finger before, so we're not jumping the gun on engagement news.
