Bling!

Patrick Mahomes wasn't the only one in his household to get a massive ring on Tuesday ... the superstar QB just proposed to his longtime GF, Brittany Matthews, with a diamond that's bigger than her knuckle!!!

Mahomes surprised his lady with a floral arrangement and bright signs at Arrowhead Stadium in Kansas City after getting his Super Bowl ring ... and Brittany's ring might be even more impressive.

Since 24-year-old Mahomes just signed the fattest contract in NFL history -- he signed a $503 MILLION extension -- it shouldn't come as a surprise that he splurged on the jewelry.

Unclear on how much he paid for it, but by the looks of it ... it wasn't cheap.

Of course, the couple has been together since their high school days ... and have been pretty much inseparable ever since.

25-year-old Matthews -- a pro fitness trainer -- has been one of Mahomes' biggest supporters since day one and definitely made sure fans heard her cheers all throughout the Chiefs' Super Bowl run this past season.

Speaking of ... Mahomes and his Kansas City Chiefs teammates finally got their championship rings for the 2019 season just before the proposal ... and they're pretty spectacular.

The champs held a special social-distanced celebration on the Arrowhead Stadium field on Tuesday ... receiving their rings for their Super Bowl LIV win over the San Francisco 49ers.

The rings -- made by Jostens -- feature the Chiefs logo (made of 60 diamonds) and 2 Lombardi trophies (made with marquise-cut diamonds) on the top ... and includes 16 rubies to signify 10 AFC West Division titles and 6 playoff appearances under head coach Andy Reid.

There are also 50 diamonds surrounding the design, which represent the 50 years since the team's first Super Bowl title.

The sides feature the SBLIV logo and player names and numbers -- and even "142.2" to honor Arrowhead's record-setting decibel rating.

The inside of the rings are just as special -- they feature the logos and scores of all KC's games throughout the playoffs ... and each recipient's autograph.

The team captured the moment Mahomes put his ring on for the first time ... and you could see the dude's smile pouring out from behind his mask!!

Look out, NFL -- these guys look like they're ready for another.

Jack Harlow takes care of his own -- and by that, we mean he's willing to spend an arm and leg to ice out his entourage, and make it look like they just walked off with the Lombardi Trophy.

The Louisville rapper -- who performed at the VMAs Sunday -- was flaunting a set of 8 rings he and his crew (AKA, Private Garden) were rocking around town ahead of and during the show. They're like championship rings -- NBA or NFL-esque -- and they look pretty sweet.

Turns out, they're more than just nice looking ... they're completely loaded with precious stones that ended up costing well over a hundred grand. Teamwork makes the dream work!

Celebrity jeweler Alex Moss -- who commissioned the custom pieces for Jack and co. -- tells TMZ the rings altogether are valued at about $110k, and that's because they're laced with VVS diamonds and 14k gold, with each ring weighing in at 55 grams.

We're told the rings have the Private Garden members' names etched in plus their 502 area code. Of course, Jack's ring is slightly more blinged-out -- he is the leader, after all.

Alex tells us he met Jack a couple years ago in the studio when he was first coming up, but just got hit up for this job a few months ago.

What does a dude nicknamed "Big Ticket" get for a chain??

How about A BIG ASS TICKET!!

TMZ Sports has learned ... New York Jets rookie Mekhi Becton is the proud new owner of a piece that is as big as his 6'7", 360-lb. frame ... copping a huge pendant in honor of his awesome moniker.

We're told Becton hit up famous jeweler Jason of Beverly Hills for the fancy jewelry ... which is made with more than a kilo of gold and 120 carats of flawless white diamonds.

So what's a piece like this worth?? We're told it's valued at a whopping $400k. Now that's an expensive ticket!!

Of course, the rookies are packin' on the ice before the season -- as we previously reported, Cincinnati Bengals first overall pick Joe Burrow just got his diamond #9 chain.

Saquon Barkley loves his personal Nike logo so much, he decided to get the thing decked out in a brand new baller chain ... and man, does this thing shine!!!

TMZ Sports has learned ... the New York Giants superstar running back wanted to treat himself before the start of the new season ... so he hit up his go-to guy, celeb jeweler Leo Frost, to whip up a diamond copy of his signature bolt emblem.

We're told the piece is made up of 18-karat white gold and VVS diamonds ... which means it's super high quality.

Of course, you've seen Frost's work in the past -- dude's done awesome chains for Joe Burrow, Henry Ruggs, Justin Jefferson, Errol Spence, Jr. and more.

Cincinnati Bengals rookie quarterback Joe Burrow just got himself an amazing welcome-to-the-NFL gift ... a diamond chain of his jersey number!!

TMZ Sports has learned ... the Heisman Trophy winner wanted to do something special after inking his massive, $36 million rookie deal, so he hit up celeb jeweler Leo Frost to whip up the one-of-a-kind piece.

We're told the awesome #9 pendant is made of 18k white gold and VVS diamonds ... sitting on an 18k white gold prong-set Cuban chain with VVS diamonds.

In other words, the rook's got taste!!

For those who paid close attention to our pre-draft jewelry roundup back in February, this should come as no surprise. As Leo told Burrow at the time, "After the draft, I'm thinking we make this a fat ass piece for you, #9? A fat #9."

Leo delivered on his promise ... flying to Cincinnati this week to hand over the final product ... and Joe loved it!!

It's been one crazy year for the Ohio boy -- he won a natty, won the Heisman, helped raise $500k for his hometown food bank, and went #1 overall in the Draft.

Fetty Wap's estranged wife wants possession of the rock he slipped on her finger when he proposed, or a fat stack of cash ... but Fetty's saying she's outta luck, 'cause he never owned it.

Leandra Gonzalez filed docs asking a judge to order Fetty to turn over the $60k engagement ring from their failed marriage.

If he doesn't produce the rock, she claims he owes her $37,000 -- the appraised value of the engagement ring. Leandra's arguing it's hers to keep because they went through with the marriage, tying the knot August 3, 2019, in Toronto.

Under the law that's called a "gift in contemplation of marriage" ... and since they said, "I do," she's saying she will take that ring -- but Fetty says there's a catch here.

Fetty's position is he never owned the ring outright when he proposed. He claims he bought the ring on consignment from the jeweler and never ended up paying for it. A few months after the marriage crumbled, Fetty says he snapped up the ring and gave it back to the jeweler.

He is willing to negotiate with Leandra, a little. In docs, the Jersey rapper offers a straight-up trade ... the jeweler keeps the diamond ring, and he will give Leandra HIS wedding band.

Luke Gulbranson -- who stirred up drama on the Bravo reality series "Summer House" -- is making the most of a his failed engagement, and helping a great cause in the process.

Luke partnered up with the folks over at IDoNowIDont.com -- the name says it all, really -- to sell an engagement ring he bought for an ex-GF before he was on the show. Fans know he brought up that 3-year relationship and the engagement ring frequently ... and it's kinda why things never took off Hannah Berner in the house.

He also talked about wanting to get rid of the ring, and it's finally happening. The Tiffany & Co. round solitaire diamond is just under 1 carat, and set in 18k white and yellow gold. It retails for $11,500 but, get this ... the starting bid at IDoNowIDont starts at $5,000. Potential bargain!!!

We're told Luke and the jewelry site will donate a percentage of the proceeds to the Leukemia & Lymphoma Society, a non-profit that's been dedicated to fighting blood cancer since 1949.

So, why L&LS? Luke's mother is currently battling Leukemia and he wants to share his gratitude to the group and its incredible work around the world.

Congrats are in order for Conor McGregor and Dee Devlin -- the UFC superstar popped the question to his longtime GF ... and she said YES!!!

The couple -- who have been together for more than a decade -- made the news official on Saturday ... showing off a MASSIVE engagement ring.

The fighter posted about dropping to one knee before Devlin's 33rd birthday, which is August 9 ... but hints it may have happened around his birthday last month.

"What a birthday, my future wife !" Conor captioned his post on Instagram.

McGregor and Devlin have 2 children together -- 3-year-old Conor Jr. and almost 2-year-old Croia.

It's been an eventful 2020 for Conor ... he kicked it off by beating Cowboy Cerrone at UFC 246 ... and retired from MMA (for the third time) in June.

Conor and Dee have spent their time traveling all over the globe ever since ... including a lavish getaway in France.

Jonathan Cheban -- AKA the "Foodgod" -- claims he had a gun pointed at him this weekend ... and now, says he's out hundreds of thousands after a crook made off with his bling.

Law enforcement sources tell us, Kim Kardashian's BFF said he was robbed at gunpoint Sunday night in Englewood Cliffs, New Jersey, where he was hanging with his mom and friend. We're told Jon and his ma were at a mall earlier in the day, and afterward ... rolled up to his pal's place.

We're told all three of them were out front in the driveway, when a young man walked up and asked for the time. Our sources say Jonathan felt something was off and told everyone to head inside, but by then ... we're told the dude pulled out a gun and was on them.

Cheban told cops the perp moved the group between two cars, to trap them ... and then pointed the gun right at Jonathan's mother's head. We're told Jonathan told the guy to take anything he wanted and the guy ended up taking Jon's Richard Mille watch, worth about $250k.

BTW, we're also told a second gunman was on the scene -- a larger man who was standing watch. Eventually, neighbors heard the commotion and came out to see what was going on -- which scared off the guys, whom we're told made off together on foot.

We're told cops were called and Jonathan is supposed to go in and help with a sketch of the suspects -- we should note, our sources say neither of these fellas had masks on.

It's interesting ... Jon's best friend, Kim Kardashian, rarely wears expensive jewelry anymore after she was robbed at gunpoint in Paris.

All eyez will be on Drake with his new twin Tupac Jesus pendants.

Mr. OVO is the new owner of what soon will become 2 of America's most wanted ... these Tupac pendants dripping with diamonds and gold. The rapper commissioned the celeb jeweler, Jason of Beverly Hills, to pull off the twin pendants depicting Pac with white and yellow diamond crowns of thorns.

Each pendant comes with a diamond chain with a total of approximately 70 carats of flawless white and yellow diamonds, plus ... over a HALF KILO of gold in total. Total price for each piece was $300k!!!

We're told Jason and his crew spent about 5 weeks completing the Pac-Jesus pieces. Drake initially came to Jason with an idea about what he wanted ... and they worked together to come up with the final tribute.

If Demi Lovato's engagement ring looked expensive, that's only because it's worth more than $2 million, and comes with some razzle-dazzle too ... TMZ has learned.

Sources with knowledge tell us ... Demi's ring would cost the average Joe off the street anywhere between $2.5 million and $5 million -- and that's due to the fact that it's a very special cut from a very well-regarded celebrity jeweler in Hollywood ... Peter Marco.

We're told Demi's diamond is an emerald cut that was hand set in platinum, and flanked on all sides by smaller (only relatively) trapezoid-shaped diamonds designs. All told, our sources say the rock comes in at well over 10 carats ... maybe even as much 20!!! No one's spilling the exact weight.

We're told Demi's fiance, Max Ehrich, spent a lot of time to make sure the design was unique -- namely, he really wanted the elongated stone for Demi. We're told he and Marco went back and forth with different side stones and angles until the ring was just right.

Their engagement came after just a few months of dating ... albeit quarantine-dating. Demi and Max first got together in March, and they've been quarantining/vacationing all over Cali since then.

After Max put a ring on it ... Demi said, "I knew I loved you the moment I met you," adding, "I’m ecstatic to start a family and life with you. I love you forever my baby. My partner. Here’s to our future!!!!"

Ellen DeGeneres and Portia de Rossi were inside their Montecito mansion when it was burglarized, but the thief still managed to get in and out undetected ... so they've turned the place into a fortress.

TMZ broke the story ... the break-in went down on July 4, and now sources with direct knowledge of the investigation tell us the couple was home. Luckily, they weren't harmed -- it's unclear if they had any contact with the suspect or suspects, who made off with jewelry.

We're told the point of entry for the burglary was a back door, and no one was captured on surveillance video -- however, Ellen and Portia are making sure that never happens again.

Our sources say they made a slew of security improvements immediately after the break-in -- which include hiring a new security company, installing laser sensors and cameras around the entire property and hiring armed patrol guards.

As we first reported ... Santa Barbara County Sheriff's Office said the crooks made off with some high-value jewelry and watches, and appear to have targeted Ellen's place due to her celeb status.

It's unclear if the break-in's related to other celeb burglaries in the greater L.A. area. The Sheriff's Office says it's working with other law enforcement agencies to investigate.

Ellen DeGeneres and Portia de Rossi are victims in a home burglary -- crooks hit their Montecito estate ... TMZ has learned.

According to the Santa Barbara County Sheriff's Office ... the theft went down on July 4, and cops believe their residence was "targeted due to the victim’s celebrity status."

No word on the value of what was taken but cops say some of the stolen items include high-value jewelry and watches.

The Sheriff's Office says it's working with other law enforcement agencies, as part of an extensive investigation, to see if this incident is connected to other recent celeb home burglaries.

It's unclear at this point if Portia and/or Ellen were home at the time of the break-in.

Ellen purchased the massive 8,188-square-foot, Balinese-style home in early 2019 for a whopping $27 million ... and it's easy to see why it comes with that price tag.

Cops offered up some free advice to other residents in the area -- which includes several celebrity estates -- to avoid social media posts about being on vacation and leaving lights and TV on while away.

"We're going to make sure we bring not 1, not 2, not 3, not 4, but 5-plus rings to Kansas City!"

K.C. Chiefs star Chris Jones did his best LeBron James impression Monday ... channeling the NBA superstar by guaranteeing multiple future championships for his team -- and it was all bold as hell!

The defensive lineman -- who just signed a MASSIVE 4-year, $85 MILLION extension to stay in K.C. -- was asked on 610 Sports Radio what his message would have been if he had been able to speak to fans at the Chiefs' Super Bowl parade in February.

That's when Jones said he would've gone all LeBron on the crowd ... and promised more parades in the future!!

"This is only the beginning," Jones said of what his speech would have entailed. "Be prepared to have another parade, and another parade, and another parade!"

Of course, 5-plus rings is unlikely ... Tom Brady's the only dude in history with that many -- and it took him 20 YEARS to get.

But, if anyone was going to do it in the near future ... it'd be the Chiefs.

They just locked up quarterback Patrick Mahomes for at least the next decade ... and they're returning nearly every other significant player from last season's Super Bowl roster.

In fact, when we spoke with star wideout Tyreek Hill about the squad ... he told us he was FIRED UP over the offense's potential in 2020.

Marilyn Monroe's pearls from her last ever photo shoot could be sitting in your collection -- the historic jewelry is hitting the auction block.

Marilyn wore faux pearl earrings and slipped on a faux pearl necklace for the photo spread -- famously known as the "Last Sitting" -- with legendary fashion photog Bert Stern.

The pics were snapped just 6 weeks before her death, and they're going up for sale through online auction house Gotta Have Rock and Roll, where they're expected to fetch a pretty penny.

The jewelry is cool, but so is the Nikon camera Bert used to take thousands of photos that day, and it's also up for auction. While Vogue Magazine supplied the props, clothes, jewelry and accessories ... the camera was Bert's personal one.

Marilyn even used the camera as a prop, spontaneously grabbing the Nikon while Bert grabbed a spare camera and kept snapping away. The auction house expects the Nikon to fetch $60,000 due to its place in pop culture.

The pearls are expected to bring in $50,000 for the earrings and $8k for the necklace.

Some of Marilyn's extensive wardrobe is also part of the auction ... we're told a gown and shawl is estimated to go for $40k and a pair of black and white checkered pants could fetch $15k. MM owned and wore the clothing.

The auction opens July 22 ... good luck!!!

NBA prospect Cassius Stanley just copped a new piece that would make the Gloved One proud -- a diamond pendant of Michael Jackson doing his iconic tilt from the "Smooth Criminal" music video!!

TMZ Sports has learned ... the projected 1st round pick in the 2020 NBA Draft hit up Clarity Custom Jewelry, a Black-owned business in L.A., to get himself a personal gift before jumping to the pros.

Jeweler Courtney Roy tells us the ex-Duke guard is a HUGE fan of the King of Pop ... so it was easy to decide what he wanted to get -- a pendant in the shape of Jackson's tilt pose from the 1988 music video!

You know what we're talking about ... about 7 minutes into the vid, MJ and his dancers defy gravity by leaning at a 45-degree angle. It's insane.

Roy tells us it took 3 different designs to get it right for the 20-year-old baller ... but ended up with a product that's decked out with white gold and 3 karats of VVS diamonds.

Roy -- who also designed jewelry for Shareef O'Neal and Patrick Beverley -- says this MJ piece is one of his favs and was thrilled (haha, MJ pun) to make it come together.

No word on how much the piece cost ... but the dude's just months away from cashing in ... so treat yo' self!!

Congrats!!
