Bling!

So be honest ... what caught your eye first ... Serena Williams' ridiculously cute baby, or her ridiculously big wedding ring?

Serena posted this pic of daughter Alexis Olympia Ohanian Jr. with the caption, "Daddy knows how much I love leopard print."

We're glad Serena posted the pic ... it gives us an excuse to re-post the wedding pics, which are some of the best in 2017.

As for our question ... we'll give you a pass and say you first noticed the baby.

A$AP Ferg's living by his credo ... by sparing no expense on a ring bearing the rapper's famed logo.

We're told Ferg dropped $20k on a new custom-designed 18-karat gold ring, iced up with pink and white diamonds spelling FERG ... made by Will Da Boss of NYC-based DWS and Co. Jewelry.

A$AP tells us he wanted to create something that feels unique to him, and got the ring inscribed with "Sky's Not the Limit" to remind himself of that every time he holds the mic.

Spending a small fortune on bling should help him get his point across too.

Making custom grillz for the whole Astros roster wasn't good enough for Paul Wall ... 'cause he just commemorated the team's first World Series with a HUGE back tattoo!!

Wall rolled through G6 Tattoo Studios in Houston for the fresh ink -- which he showed off on Wednesday with his "World Series Grillz" track bumpin' in the background.

The H-Town MC's got several tats reppin' his civic pride -- but this one's probably the most epic.

Speaking of those grillz ... the 'Stros came through Wall and Johnny Dang's shop recently to get 'em molded -- and word is they're ready for pickup!

Cardi B has a message to haters who don't believe she's really rocking a $500k ring -- just watch me shine!

The "Bodak Yellow" rapper and her fiance, Offset, hit up Ace of Diamonds in WeHo Monday night and we asked her about the Internet trolls claiming her engagement ring's fake because she hasn't been wearing it out ... and she had the best possible response.

She wasn't the only one blinging ... Quavo was also there with a record-setting piece around his neck. Inside the club, the soon-to-be-wedded couple showed some PDA ... with diamonds still shining.

Riff Raff is giving props to fellow H-Town MC Paul Wall for droppin' bank on custom grillz for the Astros -- but he's got 1 minor issue with them ...

THEY'RE TOO BALLER!!

Here's the deal ... Wall promised to make all the World Series champs personal mouth bling in 18-karat gold, which Riff says is dope (and expensive).

But when it comes to grillz, RR told TMZ Sports he rocks with 14 karat 'cause 18s and 24s don't hit the right shade of yellow.

The rapper's more of a shark-teeth-and-diamonds kinda guy ... as you can tell from the glow-in-the-dark joint he had on at In-N-Out.

Joe Jonas and Sophie Turner pulled out all the stops Saturday night for their engagement dinner.

The celebration went down in NYC and lots of people showed up ... brother Nick Jonas, Ansel Elgort from "Baby Driver," film director Justin Ervin, Ashley Graham, Tom Holland and model Georgia Fowler.

Joe and Sophie got engaged 3 weeks ago and she posted a pic of a gigantic rock.

No word on when they're tying the knot.

The Houston Astros are getting some serious bling long before their rings arrive -- 'cause Paul Wall says he's hookin' up EVERY PLAYER with a custom gold grill.

The craziest part -- the rapper and his business partner Johnny Dang are trying to get it done BEFORE the World Series parade on Friday!!

We got Wall and Dang after their hometown 'Stros clinched the Series ... and they told TMZ Sports they ain't sparing any expense when it comes to H-Town's MLB champs.

Not only is the entire 40-man roster (and their hot WAGs) getting their own personalized teeth swag -- but each one is coming in 18 karat gold!!

Wall says the players might have to break out the plastic if they want a full mouth of diamonds ... but beyond that, everything's fair game.

Astros third baseman Alex Bregman approves.

Cardi B's walking around with a fortune on her left hand ... because Offset definitely didn't skimp when he put a ring on it.

The Migos rapper dropped $550k on Cardi's engagement ring, which took a month and a half to make ... according to the owner of NYC's Pristine Jewelers. It came together just in time for Offset's live onstage proposal, but means he really must have been sweating during their brief breakup.

Cardi's shiny 8-carat stone's surrounded by 2 half-carat pear diamonds and 2 carats worth of pink and white stones. The ring's totally custom made in the raindrop shape Offset wanted.

It also worked out perfectly -- we're told the ring was finished by the day of the Philly Powerhouse concert and he picked it up just hours before he proposed.

As we reported ... Offset could get a big chunk of his ring money back -- he and Cardi B are wanted for a TV wedding special that could land the couple one million bucks.

Kim Kardashian gave the appearance she's going back on her word to swear off flashy jewelry in public, but it was nothing but a trick ... TMZ has learned.

Kim was wearing a couple of diamond rings over the weekend as part of her Cher costume at George Clooney's and Rande Gerber's Casamigos party. Seemed odd because she promised to tone down the bling after the Paris robbery.

Thing is ... those rings weren't even close to the real McCoy. Our Kardashian sources tell us Kim was, appropriately for Halloween, wearing nothing but costume jewelry.

Word. Kept.

DJ Khaled is hooking up his famous son, Asahd, with 2 things for his 1st birthday -- a sick diamond-studded watch, and a ton of patience ... 'cause he can't even wear the watch yet.

Khaled's wife, Nicole Tuck, commissioned Haute Living -- which also threw the birthday bash -- to make a VERY nice watch for Asahd. The piece is laced with more than 600 diamonds which weigh in at 11.65 carats ... all for just over $100k.

We're told the watch is a Franck Muller model in rose gold, with Asahd's name and birth date engraved on the back. It's also adult sized, and seeing as how Asahd just turned 1 ... he probably won't be ballin' out anytime soon. Good to know it's waiting on deck though.

You da best, Mom & Dad!

Gucci Mane's diamond heart has just 1 key ... and luckily his new wife Keyshia Ka'oir is holding it.

The newlyweds got a pretty baller gift from Gucci's best friend -- Pierre "Pee" Thomas, CEO of Quality Control Music -- two 28-carat diamond necklaces, and each has an additional 15-carat diamond pendant attached.

Gucci got the heart pendant, and wifey has the key. The jewelry -- made by Wafi Lalani at Jewelry Unlimited in ATL -- was delivered in an awesome case that plays Gucci's song "Curve."

Now, that's how ya lock it down.

Chanel West Coast just one-upped Future in the mask game ... wearing one that's bigger and more bedazzled than the one he wore on the BET Awards red carpet.

Chanel dropped a few thousand bucks to rent the blinged-out ensemble in her "New Bae" video featuring Nicki Minaj's ex, Safaree Samuels. It's made by Marianna Harutunian, the same designer who created the custom masks Future and his daughter wore to the BET Awards in June.

The mask CWC wore retails for $3,000 since it's made with over 8,000 Swarovski crystals. She also wore a Harutunian-designed crown and matching bodysuit in the vid which retail for $3,800 and $3,500, respectively.

Chanel's shine would've cost her more than $10k, but sadly she didn't get to keep the duds since they were on loan.

Not exactly a bad thing ... she looks better with the mask off.

Offset made a jewelry run in NYC, with his gf Cardi B apparently in tow, but made it clear he wasn't icing her up ... 'cause he doesn't need to anymore.

The Migos rapper came out of the jeweler Wednesday afternoon loaded down with a new pendant and 3 flashy watches worth at least one exotic sports car. When we asked if any of the new gear was for Cardi ... Offset had the perfect response -- especially because we're pretty sure she was in earshot, waiting in their ride.

Well, we know he's bought her bling before ... but that was B.B.Y. -- before "Bodak Yellow" blew up.

Fergie's fully owning the single life down in Brazil ... in a micro-mini outfit and no Josh Duhamel wedding ring.

Ferg touched down in Rio Wednesday, and tried to draw eyes away from her leggy leopard-print outfit and knee-high boots by holding up her left hand. She flaunted 4 rings spelling out F-E-R-G. Mind you, this was the day before she and Josh announced their separation.

As we reported, they split earlier this year, and say they took time to adjust before announcing it.

Fergie's down there to perform in the Rock in Rio music festival. Josh is back home with their son, Axl, and was seen Wednesday ... still wearing his wedding band.

Afrojack didn't just ice up his own neck for his birthday, he made sure his whole crew was shining ... even though it cost him SIX figures! Best. Friend. Ever.

The Dutch DJ ordered 5 chains with custom Afrojack logo pendants made with white gold and diamonds. He bought one for himself, but the other 4 went to his closest friends. A source close to Afrojack tells us it was a thank-you for supporting him during his 10 years in the biz.

We're told each of the 5 pieces cost $20k -- and Afrojack hit up celeb jeweler Ben Baller of IF & Co. because he was impressed by Lil Uzi Vert's new chain. The goodies were delivered last weekend to his 30th bday bash in Holland.

Talk about a happy customer ... we're told Afrojack ordered 5 more for other members of his entourage.

We're saying he's spending like there's "No Tomorrow" -- his new track -- but he's got stacks for days.

L.A. Lakers rising star Larry Nance Jr. is officially off the market ... 'cause the NBA baller just proposed to his college sweetheart with a MASSIVE diamond ring!!

The 24-year-old and his longtime girlfriend, Hailey Pince -- a fellow U. of Wyoming alum -- announced the big news on social media Tuesday by showing off the huge rock.

LNJ and the aspiring model have been dating for over 3 years ... and he explained his decision to pop the question by channeling his inner Beyonce, saying "I liked it, so I put a ring on it."

Nance can reportedly make up to $7 million over the next 3 years ... so yeah, dude can afford to splurge on his girl.
