Bling!

Travis Scott's way to his girl's heart? Expensive jewelry ... inspired by his own hit song.

The rapper's been busy showering Kylie Jenner with birthday gifts this week, including this diamond necklace with a pendant related to his track, "Butterfly Effect." We're told Travis reached out to jeweler Elliot Avianne 2 weeks ago to get it done in time for her bday.

The piece is made up of 28 carats of VVS diamonds, and we're told it set the rapper back about $60,000.

We know Travis also went to the movies with Kylie for her b-day, but that's not all ... he took a page out of Kanye's book and set up a private orchestra show for her too.

Iggy Azalea still has ex French Montana wrapped around her little fingers.

The "Mo Bounce" rapper stepped out Thursday in West Hollywood wearing the diamond bands French gifted her almost a year ago, when they were still a thing.

Iggy hasn't had great luck with rings in the past ... she gave back her huge yellow engagement rock from Nick Young after they broke things off, but it looks like it's a different story with the $100k in ice from French.

Iggy's been linked to other dudes since ... and no word on who this guy is, but it looks like she's still on good terms with French.

The couple that sings together, blings together ... if you're Offset and Cardi B.

TMZ has learned the Migos rapper dropped 6 bands on his girl's new chain, which is blanketed in diamonds ... right down to the digits.

We're told Cardi was a huge fan of Offset's recently purchased pieces, including his $100k raindrop pendant, so about a month ago they hit up his guys at Avianne & Co Jewelers in NYC.

Cardi wanted something original so she handled the design and had him replicate her ILY hand gesture. Dip the whole thing in 20 karats of diamonds, plus 15 more karats on the chain and BAM!

Nice icy teamwork.

Hilary Duff just learned the hard way about the danger of posting vacation pics on Instagram -- it sets up her empty crib as an easy target for crooks on the hunt for high-end jewelry.

We're told someone broke into Hilary's Bev Hills pad late Wednesday. Someone broke through a door, rooted around and discovered Hilary's stash. The alarm never went off.

Our sources say the thief or thieves made off with bling worth hundreds of thousands of dollars.

Hilary and her fam were in Canada. She posted a bunch of pics and vids, making it clear she was out of the country. She's still there, so cops still don't know the extent of the heist.

Hilary joins a long list of celebs who were hit by burglars ... including Scott Disick, Ronda Rousey and Michael B. Jordan.

21 Savage is going all out when it comes to a personalized piece of jewelry he just scooped up -- it's not only a replica of his mug ... it's dripping in diamonds.

Gabriel Jacobs, owner of Rafaello & Co, just debuted the Atlanta rapper's new split personality pendant -- one side is Savage's face, right down to his tats. The other side is a Jason Voorhees mask ... a tip of the hat to his "Slaughter King" mixtape.

Gabe tells us it took him more than 2 months to finish the pendant. The head is covered in 100 carats of VVS grade, near flawless, natural white diamonds. That's what $125,000 will get ya!

This piece AND Amber Rose? Who's having a better summer than Savage?

Rob Kardashian may be guilty of revenge porn, but he says Blac Chyna is trying to get her own revenge ... in the jewelry department, so claim sources connected to Rob.

Our Kardashian sources say a few days before Rob went off Friday by slut shaming Chyna, he was courting her with bling. They say a jeweler came to Chyna's house with 7 pieces of jewelry, worth a total of $250k. Rob wanted Chyna to pick one as a gift from him.

The jeweler decided to leave all 7 so Chyna could mull it over. Then Rob went crazy, and our Kardashian sources say she only returned 3 pieces, keeping a ring and 3 tennis bracelets ... worth around $125k. We're told Chyna tried charging a significant amount on Rob's card for some of the jewelry, but it was flagged and denied by Rob's business manager.

We're told the jeweler has contacted Chyna several times, telling her the gift was off the table and asking her to return all of the items, but it's fallen on deaf ears.

To add insult to injury, Chyna wore the 3 tennis bracelets to court Monday when she got a restraining order against Rob.

Chyna begs to differ. Celebrity lawyer Lisa Bloom, who reps Chyna, tells us Rob outright gave her all 7 pieces as a gift so she had no obligation to return anything. Bloom says after Rob's tirade, Chyna decided to return 4 items but kept the tennis bracelet set because she liked them and as she saw it returning 4 items that were legally hers was a gift to Rob.

It's now the Wimbledon of jewelry disputes.

A rep for Rob declined to comment.

Robert Kraft's got a new homie, Meek Mill -- and he likes the rapper so much, he let him wear his brand new Super Bowl ring!

The New England Patriots owner ran into Meek in Miami -- and the two hit it off. Shouldn't be too big of a surprise considering Kraft is tight with Meek's MMG label owner, Rick Ross.

Remember, Kraft once let Vladimir Putin try on a Super Bowl ring and the Russian leader straight JACKED it.

But Meek's no Putin -- he gave the ring back (good thing, since he's still technically on probation).

Tyga is fully out of the Kardashian spotlight ... but he's still treating himself to a life of luxury.

The rapper just picked up a baller Goyard pendant and 14 karat white gold chain with 60 carats worth of diamonds ... all for $188,000. The necklace also has a custom clasp with the name of his label ... Last Kings Records.

The ice, courtesy of If & Co. Jewelers, was delivered to Tyga earlier this week.

We're told his bling is already paid in full too ... so he doesn't have to worry about another bill in the mail.

Blac Chyna's side piece, Ferrari, is fighting fire with fire by posting more semi-naked photos of him in bed with Rob's baby mama.

In both pics, Ferrari and Chyna both appear to be naked under the covers in the bed where Rob insists he and Chyna conceived Dream. We're told the pics are supposed to send a message to Rob -- Ferrari ain't broke and banging Blac Chyna ... he's just banging her.

Sources close to Ferrari tell us the photos were actually taken a month ago when Rob had no idea Chyna was hooking up with Ferrari. They are extra insulting since Chyna is wearing both Ferrari's $250k chain and the jewelry that Rob bought her.

We're told Ferrari is retaliating because Rob called him broke on social media ... and Ferrari insists that's just not the case.

Lindsay Lohan's getting the party started a little early for her birthday ... hitting the beach at one of her favorite spots in Greece.

The soon-to-be 31-year-old arrived in Mykonos Thursday and enjoyed a boat ride and a refreshing dip in the sea. Even though the celebration has begun, her bday's not actually until Sunday.

What's interesting -- Lindsay's rocking a green emerald ring ... very similar to her old engagement ring. Don't be fooled, though -- we're told she just loves emeralds, and it's actually part of her new jewelry line ... aptly called Lohan by Lindsay Lohan.

Happy early birthday, Whatsyourname!

Here's proof Bill Belichick is secretly a happy, smilin', ooey-gooey romantic ... courtesy of a lovey-dovey photo shoot with his girlfriend!!

The New England Patriots coach showed off his MUCH softer side with his longtime GF, Linda Holliday, for N Magazine ... strolling through meadows, holding hands, and other mushy stuff.

B.B.'s only wearing one of his Super Bowl rings, though (he went with S.B. 49) ... and even lets Holliday wear it on THAT finger for a couple pics.

The shoot almost comes off as a wedding photo shoot.

Soooooo ... Bill gettin' another ring this year???

Miranda Kerr just forked over millions of dollars worth of jewelry to the U.S. government because someone may have bought them for her with stolen overseas money.

Miranda surrendered $8.1 million in jewels to the U.S. Justice Department Friday from her safe-deposit box in L.A. The jewels were given to her by a Malaysian financier ... allegedly with ill-gotten money.

International lawsuits have been filed alleging the cash was illegally taken from a Malaysian sovereign-wealth fund, and that some of the money was used to buy gifts for various celebs ... including Miranda and Leonardo DiCaprio.

Leo just handed over some of his prized possessions -- including an Oscar won by Marlon Brando that was gifted to him. He surrendered the goods a couple weeks ago, the result of the same probe.

Neither celeb was named as a defendant in the lawsuits.

Future and his daughter weren't about to take their masks off at the BET Awards 'cause they cost a damn fortune to make.

You might have noticed Future and his little girl, Londyn, rocking Bane-like masks Sunday on the red carpet, and even during the rapper's performance at the show. Well, the hardware didn't come cheap ... try about $9,000 for 3 of 'em.

Sources with direct knowledge tell us Future's camp hired designers Marianna Harutunian and Xtina Milani to create 3 unique masks for Future and Londyn.

We're told Future dropped between $2,500 to $3,000 per mask -- all of which were made with brass frames and Swarovski crystals. Londyn rocked rose gold brass with gold crystals. Future had one for arrivals and another for his performance ... both with clear, black and orange crystals.

They took about a week and a half to make. Clearly, Future's was designed so he could rap through it.

Rich The Kid hopefully is truly rolling in dough, because he's dripping in jewelry, and his latest acquisition set him back $75k.

Rich was leaving Peter Marco Extraordinary Jewels Of Beverly Hills on Rodeo Drive Saturday, when he told us he dropped the loot to snap a Papa Smurf chain.

As we reported, made a $2.5 million deal with Interscope last week, and celebrated in NYC by spending $140k a watch and another $100k on a chain.

Rich the Kid has lived up to his name after a huge payday from his new record label, so he can afford to crank up his bling game.

The rapper hit up NYC Luxury for some fresh ice the day after signing his $2.5 million deal with Interscope. We're told he got a chain, a diamond Audemars Piguet watch and bracelet for $140k and has another chain being made with the "Rich Forever 3" album logo ... for north of $100k.

We got the Kid out in Midtown Manhattan showing off his new choker chain ... all 34 carats and 380 gold grams.

Here's Tom Brady doing the anti-Dan Marino -- sporting a fist full of Super Bowl rings ... 3 days after he added #5 to his collection.

Why is he still wearing the hardware out in public? Why not? Wouldn't you?

Brady and his wife/concussion whistle-blower Gisele were out celebrating Dia dos Namorados -- the Brazilian equivalent to Valentine's Day on Monday.

The location of the celebration is unclear -- but you can see Tom rockin' 4 rings as the event band busts out a custom freestyle about Tom and Gisele's healthy eating habits.
