Bling!

Sylvester Stallone is about to score a massive payday after putting his watch collection up for auction, because one of the timepieces could fetch a literal king's ransom.

As you might have heard, the 'Rocky' star is selling 11 watches from his personal collection through Sotheby's next month ... and one crown jewel, in particular, has a watch expert going bonkers 'cause it's incredibly rare (and damn expensive).

YouTube personality Nico Leonard van der Horst -- who knows all things watches -- tells TMZ ... he simply can't believe Sly is parting with his ultra-rare Patek Philippe Grandmaster Chime.

Taylor Swift is shaking things up for the start of the European leg of her 'Eras' tour ... introducing a slew of changes for the new shows, and her fans absolutely love it.

The singer kicked off the new dates for her record-breaking tour with a stop in Paris Thursday ... debuting a couple key changes right out of the gate. As eagle-eyed Swifties quickly noticed, Taylor donned a new 'Lover' bodysuit for the intro of her tour.

Instead of the pale pink and blue sequined number -- which Taylor famously wore in the concert film -- the singer wore a vibrant orange bedazzled bodysuit. She also notably ditched her getup for the 'Fearless' era, swapping in a new gold and black fringe dress.

The ring Kevin Hart gifted to Tom Brady for being such a good sport during Sunday night's roast wasn't merely a prop ... TMZ Sports has learned it's the real deal -- coming in with a staggering worth of $40,000!!!

We're told celeb jeweler Jason Arashaben, CEO of Jason of Beverly Hills -- who actually created TB12's final Tampa Bay Buccaneers Super Bowl ring -- was the mastermind behind the piece, tasked with completing it in time for Netflix's "The Greatest Roast of All Time: Tom Brady."

Jason threw the kitchen sink at the bling ... loading it with just under 400 diamonds, rubies and sapphires. A spokesperson for the jeweler tells us it's all set on yellow gold, weighs around 6 carats -- and would cost normies about as much as a brand-new car to own.

Gypsy Rose Blanchard has already given back her wedding ring to estranged husband Ryan Anderson ... because the piece of jewelry meant quite a bit to him, TMZ has learned.

Sources close to Gypsy Rose tell TMZ … she felt it was the right thing to give back the ring -- as it was a family heirloom given to Ryan by his mom. We're told Gypsy Rose left the ring with Ryan when she made the decision to end her marriage  ... along with an apology note next to their bed on March 22.

The note read ... "I'm sorry, you and I deserve happiness."

TMZ Sports has learned celeb jeweler The Ice Champ is the man behind the royal piece ... making the crown for Garcia's highly anticipated boxing match with rival Devin Haney on Saturday night at Barclay's in Brooklyn.

Leonardo DiCaprio y su novia -Vittoria Ceretti- no están comprometidos a pesar de las grandes especulaciones después de que ella luciera un anillo en ESE dedo, TMZ ha indagado.

Fuentes con conocimiento directo nos dicen que Leo no le ha hecho la pregunta a la modelo italiana, a pesar de que muchos asumieron que era el caso después de que ella luciera un anillo en su dedo anular mientras almorzaban en un restaurante de Los Ángeles el martes.

Mientras que la joya podría haber parecido bastante reciente para algunos, nuestras fuentes dicen que Vittoria en realidad ha estado usando el anillo desde al menos 2022, mucho antes de comenzar a salir con Leo.

Leonardo DiCaprio and his girlfriend, Vittoria Ceretti, are not engaged despite major speculation after she was rocking a ring on THAT finger ... TMZ has learned.

Sources with direct knowledge tell us LDC has not popped the question to the Italian model -- even though many assumed that to be the case after she flaunted a sparkler on her ring finger while out to lunch with her man at a restaurant in Los Angeles on Tuesday.

While the bling might've looked fairly recent to some -- our sources say Vittoria has actually been wearing the ring since at least 2022, well before she started dating Leo.

Celebrity jeweler Shuki International tells TMZ Sports he's willing to tear up his court judgment against Antonio Brown ... if the former NFL star simply gives him back his diamonds.

Shuki's been in a war with AB over the jewels for years -- writing in a lawsuit back in 2023 that the ex-Tampa Bay Buccaneers wideout borrowed his iconic "Shuki International" finger covers and other prized possessions in 2022 ... but never paid for them or returned them.

Shuki actually won the case against Brown last month after the footballer failed to fight the suit ... with a judge ordering AB to pony up $1,095,000 million.

But when we spotted Shuki out in LA this week ... he told us Brown hasn't paid yet -- nor has he attempted to give back the items.

Shuki said he actually had a conversation with Brown over it all -- and AB apparently made it clear to him "he's not going to pay."

"Which is OK," Shuki continued, "just tell him to bring back the rings so we can settle."

Shuki said he doesn't harbor any animosity toward Brown despite the tense situation -- in fact, he said if AB hops on a new music track with him, he might be willing to forgive the whole thing right then and there.

But, getting his items back is obviously priority No. 1 for the jeweler.

"'Hey, bring back the ring,'" Shuki said in a message to Brown. "'Be cool. Be nice. I love you like a brother. But I don't think it's fair to hold something that you don't own. Especially with a court order now.'"

Paul Pierce is just the latest celebrity to fall prey to Los Angeles' burglary epidemic ... the former NBA superstar's home was broken into Friday night, and the perpetrators got away with luxury watches and over $100k in cash.

Law enforcement sources tell TMZ Sports the 46-year-old 10x NBA All-Star's pad was hit when Pierce wasn't home, and a mind-boggling amount of personal treasure was stolen.

Amongst the burglarized items were expensive watches, 6 figures in cash, and a safe ... which police are currently trying to track down.

As for the criminal investigation, we're told cops have been combing through video from the scene, hoping to find a critical piece of evidence that'll crack the case.

No arrests have been made.

While he's the latest, he's not the first big-named star to have their personal spaces violated, and their belongings stolen ... it's been an issue in the City of Angels for years.

Post Malone, Bella Thorne, Yasiel Puig, Rihanna, Quentin Tarantino, Drake and so many other stars have fallen victim.

In fact, the LAPD recently talked about "burglary tourists" from South America who travel to Los Angeles solely to target luxurious mansions.

Police say the rings sometimes use high-tech equipment like jammers to bypass security systems.

It's unclear if one of these rings is behind the Pierce burglary.
