Jeff Bezos and Lauren Sanchez

Jeff Bezos and Lauren Sanchez’s Venice wedding festivities are hitting rough waters -- literally -- as local protests and security fears have their security team scrambling to adjust plans by the hour ... TMZ has learned.

Multiple Venetian sources tell TMZ ... the Amazon founder’s security team is making changes in real time to key locations for the billionaire bash, with several options being moved around at the last minute over concerns about unrest in the area.

We're told one of the main issues is Bezos’ mega-yacht is expected to dock in a lagoon -- which is now being eyed as a possible safety hazard amid ongoing protests in the area. The problem is, the yacht is so massive, it has limited docking options in Venice’s tight waterways. Our sources say Bezos' team may opt to keep the vessel far from the land and ferry guests in and out by tender boats instead.

Amid rumors about his relationship with Katy Perry hitting a rough patch, Orlando Bloom is playing it cool -- and making sure to show up and show face for her in Australia.

The actor was spotted in Perth on Sunday, strolling with their daughter Daisy Dove perched on his shoulders -- surrounded by a crowd, looking carefree and soaking in the sights.

The father-daughter duo looked in good spirits, but there was a noticeable absence of Katy -- who’s clearly got her hands full with her "Lifetimes" tour.

Venice is gonna be flooded with yachts this week in the wake of the Bezos-Sanchez wedding, and it's scaring a bunch of billionaires away from the region.

Sources with direct knowledge who rep some of these uber-rich folks tell TMZ ... non-celeb billionaires with big 'ol yachts had made plans to tool around the Mediterranean in July are moving their trips to August.

As one put it, "Venice is gonna be a s**t show with all the yachts!" There's a whole competing culture in the yachting world, where one group (mostly celebs and techies) loves being around other big boats for a d***-measuring competition, and the other group just likes the solace of their own boat.

Jeff Bezos and Lauren Sanchez’s impending Italian wedding is turning up the heat for them and their A-list guests -- but locals are still fired up and not shy about it!

A giant banner has been rolled out in Venice's iconic St. Mark’s Square demanding Bezos pay more taxes, especially if he’s shelling out to rent the city for this wedding -- a bold message from campaign group Everyone Hates Elon and Greenpeace that’s impossible to ignore.

An Everyone Hates Elon spokesperson blasted Bezos for shutting down massive chunks of the city for days to get married ... calling it ridiculous the third-richest man in the world, worth $220 billion, could do so while the government struggles to fund public services.

Jeff Bezos and Lauren Sanchez have changed the game when it comes to "foam fingers" ... 'cause the two stars played around at a foam party days before exchanging bling for their ring fingers!

The major couple was spotted on Jeff's megayacht -- the Koru -- off the coast of Europe Sunday ... partaking in a lavish foam party for Lauren's son Evan's 19th birthday.

JB and LS were covered in suds on the deck ... engaging in a little PDA a few days before their star-studded wedding.

Jeff Bezos and Lauren Sanchez didn’t exactly kick things off with a fairy tale -- 'cause the couple went public in 2019 after rumors swirled about an affair ...

Then, boom ... Jeff signed off on a $38-billion divorce like it was next-day delivery, and a few months later, Lauren ditched her Hollywood hubby Patrick Whitesell -- and by Wimbledon that same year, the lovebirds were playing doubles with flirty giggles and loving stares.

By 2022, Jeff was smacking her butt like it owed him money, and by the next year, he dropped a giant rock on her finger -- prime commitment!

Lauren Sanchez does not want to sully her best outfits on some dinghy ... because we've learned for at least part of her big wedding week, she and Jeff Bezos will be staying at a super-swanky Venice hotel.

Multiple Venetian sources with direct knowledge tell TMZ ... Bezos and the future Mrs. Bezos will be staying at the Aman Venice, a landmark built in 1550.

Furthermore, our sources say the Aman has been blocked out entirely from Wednesday, June 25, through Sunday, June 29. We're told wedding guests will also be staying at the hotel.

Orlando Bloom is on the ultra high-profile guest list for Jeff Bezos and Lauren Sánchez's approaching wedding ... and TMZ has learned the actor's going stag amid rumors of his relationship with Katy Perry getting rocky.

Sources tell TMZ ... OB plans to attend the days-long wedding celebration in Venice, Italy, taking place later this month ... and Katy ain't going to be by his side -- but in this instance, there's a perfectly logical explanation.

Katy is currently on tour in Australia, rockin' 15 sold-out shows -- and those dates overlap with the billionaire's bash. And Katy's tour was planned way before Jeff and Lauren locked in their lavish European nuptials.

Jeff Bezos and fiancée Lauren Sanchez’s star-studded Venice wedding has celebs buzzing -- but locals? Yeah, they’re not exactly rolling out the red carpet.

Venetians aren’t holding back -- posters slamming the Sanchezos wedding are plastered all over town, and one even dropped a giant red X over his name from a historic bell tower of Venice's San Giorgio Maggiore Church.

With their "No Space for Bezos" posters, locals are going out on a limb -- loud and clear -- slamming the billionaire’s flashy impending three-day wedding takeover of their city.

Lauren Sanchez’s wedding to Jeff Bezos is the talk of the town, and frankly, the world -- and TMZ’s got some more exclusive deets, straight from her big brother!

TMZ caught up with Paul Sanchez outside a Home Depot Thursday, and he’s doubling down on what we all know -- Lauren and Jeff's wedding is gonna be huge. But, he takes it a step further, saying it's gonna be just as big as Princess Diana’s 1981 wedding to King Charles.

Catch the full video, 'cause Paul shared some deets on the venue, and the celebs he’s hoping to meet at this star-studded affair ... plus, what he's planning to gift his sis and bro-in-law-to-be, considering they already have it all.

Jeff Bezos and Lauren Sánchez's summer wedding is shaping up to be the event of the year -- ultra-luxe, ultra-exclusive, and a guest list stacked with A-listers!

Eva Longoria, Katy Perry and Orlando Bloom, Oprah Winfrey, Gayle King, Kris Jenner, Kim Kardashian and Jewel are among the lucky ones who scored an invite from the Amazon billionaire and his soon-to-be wife to their summer Italian affair.

We're also told Ivanka Trump and Jared Kushner, as well as Karlie Kloss and her husband Joshua Kushner made the list. Our sources say Barry Diller and Diane von Furstenberg, film producer Brian Grazer, models Brooks Nader and Camila Morrone secured an invitation.

Jeff Bezos and Lauren Sanchez are getting set to walk down the aisle, according to multiple reports.

After a 2-year engagement, the jet-setting couple is finally sending out wedding invites, saying they will tie the knot this summer in Italy, per the New York Post and Puck News.

As you know, Jeff and Lauren have had a whirlwind romance since 2019 when they first stepped out in public together.

Jeff Bezos was triggered Sunday after reading stories that he was tying the knot with his fiancée Lauren Sanchez next weekend in Aspen.

Bezos launched Trump style at the media, saying, "This whole thing is completely false - none of this is happening. The old adage, 'don't believe everything you read' is even more true today than it ever has been."

But he wasn't done ... "Now lies can get ALL the way around the world before the truth can get its pants on."

Lauren Sanchez has the whole blended family gathering down to a science ... celebrating her son Nikko's graduation with her soon-to-be-husband, her ex and his wife!

The TV personality shared a series of photos from Nikko's college grad party, featuring Jeff Bezos, Nikko's dad -- NFL Hall of Famer Tony Gonzalez -- and Tony's wife, October. The adult squad seemed even to enjoy each other's company, posing for multiple pics together.

Mama Bear posted a tear-jerking video in honor of her boy, who's 23 now ... comprised of pics of Nikko before cutting to an emotional speech Sanchez gave during the festivities -- and, ya gotta watch it for yourself because it's LS at her most raw.

Jeff Bezos and Lauren Sanchez might be worth billions -- but they're just like us ... 'cause sometimes, they just want some basic lo mein, and when they do -- they dine in.

The Amazon founder and his fiancée -- who are quite accustomed to the high life -- rolled into a relatively dinky restaurant in Miami Sunday called Tropical Chinese and they sat down for a meal with another couple for dinner.

If you think they'd stand out like a sore thumb in a joint like this ... well, you're right. As you can see in these photos obtained by TMZ -- Jeff and co. most certainly looked like celebs in a very normie part of town. And, in a modest establishment like this -- perhaps doubly so.

The reason we know that's true ... some of the restaurant patrons -- and some staff too, it seems -- came over to chat it up with JB and his crew ... apparently in awe he was there.

Jeff didn't seem to mind the attention ... he was seen smiling and yukking it up with the commoners -- and once he and his party were finally able to sit down and munch, we're told they appeared to be delving into the Peking duck ... which goes for about $78 there.

It's a whole two-course deal there and certainly one of their pricier offerings. Everything else is fairly affordable ... a fried rice order at this place costs between $15 and $26.

Considering Jeff and Lauren are used to a certain standard of living in their day-to-day -- this must've been a nice change of pace for them. Hey, billionaires need greasy noodles too!

Jeff Bezos must have had one helluva bedroom romp on his 60th birthday thanks to his fiancée, Lauren Sanchez, and her wildly sexy outfit!!!

As Bezos rang in a new decade of his life Friday, Sanchez prepared a very intimate surprise for the billionaire mogul. Well, maybe not so intimate because she shared it with the entire world!

Sanchez posted an Instagram photo of herself wearing a jaw-dropping, all-black ensemble, featuring a lace Dolce & Gabbana tight-fitting dress to go along with her bra and panties. She traded in her usual wavy hairstyle for a straight black mane that was heavy on the bangs. She also showed off her engagement ring and a necklace around her neck.

The temptress didn't have to say much after her stunning display, writing just three words in the caption, “Happy birthday baby 🖤.”

In an earlier Friday post, Sanchez offered more substance, talking about how Bezos fills their home with laughter and has a smile that lights up the room. She then wished Bezos peace and "joyous celebrations" in the new year, signing off with "Love you."

She accompanied her message with a bunch of sweet photos -- one of which showed Bezos as a youngster wolfing down a piece of chicken. Bezos responded in the comments section, “Happy to be going around the sun with you. ❤️."
