Honeymoon crashers! Now Lauren Sanchez parties in Paris with Leonardo DiCaprio, Sean Penn and model Brooks Nader

Newlywed Lauren Sanchez looked sensational as she enjoyed a night out in Paris, France with some of her A-list friends, including Leonardo DiCaprio and Sean Penn, on Tuesday.

It marks Sanchez’s first public outing since she and Amazon tycoon Jeff Bezos, 61, tied the knot during their lavish $50million Italian wedding weekend last month.

Sanchez and Bezos hosted 200 elite guests during the controversial three-day extravaganza — which many dubbed the ‘Wedding of the Century.’

The celebration continued this past weekend as the couple spent their ‘honeymoon’ partying on a yacht with recently split couple, Katy Perry and Orlando Bloom, in Capri.

And on Tuesday night, a solo Sanchez ventured to Paris without her billionaire husband where she met up with Oscar-winners DiCaprio, Penn and model Brooks Nader and more stars for an upscale dinner at Laperouse restaurant.

The new Mrs. Bezos, 55, made jaws drop upon arrival as she flashed her ample cleavage in a red latex dress by Versace, which retails for over $3,500.

She finished off the look with her hair sleek and straight, and carried a black crocodile Hermès Kelly bag, which typically has a resale value of over $50,000.

Sanchez was photographed exiting Laperouse, which is situated along the Seine and boasts private dining rooms, with a crew of security guards surrounding her.

She smiled while being escorted to a nearby SUV as locals and paparazzi looked on in awe.

Sanchez’s model pal Nader put on an X-rated display for their night out in Paris by going braless under a black see-through pussy bow blouse.

The shocking top left nothing to the imagination as Nader, 28, confidently exited Laperouse with a security guard in tow.

The blonde bombshell completed her racy outfit with skintight capri pants, sky-high heels and a shiny black clutch.

As for her glam, Nader’s plump pout was drenched in lip gloss and her long hair looked extra voluminous for the invite-only occasion amid Paris Fashion Week.

Nader’s younger sister Sarah Jane Nader was also in attendance.

The brunette beauty was pictured walking behind her model sister in a daringly low-cut top. 

DiCaprio — who was recently branded a ‘hypocrite’ for associating with Bezos — tried to keep a low-profile as he left the restaurant before Sanchez and Nader.

Dressed in a casual all-black outfit, the 50-year-old famous face was barely visible behind an N95 and a black baseball cap, which he pulled down to cover his eyes.

The look resembled viral photos from the Bezos-Sanchez wedding that showed a tuxedo-clad DiCaprio seemingly trying to ‘hide’ from cameras by wearing a hat low down over his eyes and nose.

Missing from DiCaprio’s side on Tuesday night was his supermodel girlfriend Vittoria Ceretti, 27.

Instead, DiCaprio was joined by a single bodyguard as he made a beeline to a nearby chauffeured car parked outside of Laperouse.

Penn, 64, rolled up the A-list gathering with his stunning 30-year-old girlfriend, Valeria Nicov. 

The Mystic River star looked slimmer than ever in a trendy neutral-toned outfit as Nicov, wearing a white blouse and black slacks, trailed behind him.

The couple, who made their red carpet debut last December, were photographed walking into the restaurant separately. 

Socialite Natasha Poonawalla was also on hand for Sanchez’s star-studded dinner in Paris. 

Bezos’ absence from the dinner party was likely due to a scheduling conflict as he is expected to attend Allen & Co.’s annual leadership retreat in Sun Valley, Idaho this week.

Days before Sanchez’s Paris trip, the journalist and Bezos were spotted partying on a superyacht in the Mediterranean during what many believed was their honeymoon.

But instead of spending one-on-one time, the couple were joined on the boat trip by Katy Perry and Orlando Bloom — who recently confirmed their breakup — and several other friends as they soaked up the sun over the weekend.

However, DailyMail.com recently learned that the trip was technically not an official honeymoon for Bezos and Sanchez, who appeared to be enjoying their extended vacation following their Venice nuptials.

The luxe event, which not only featured their actual wedding but multiple themed parties and brunches, saw the couple surrounded by 200 friends and family.

According to The Guardian, over 90 jets flew into the airport in the romantic city.

A-listers like Kim Kardashian, Ivanka Trump, Oprah Winfrey and Kris Jenner all made an appearance, as well as Microsoft co-founder Bill Gates.

Ellie Goulding performed at their reception, while Usher also sang at their pajama-themed brunch the next day.

The A-list wedding was met with fierce backlash by locals who gathered in St Mark’s Square, the iconic heart of Venice, to protest during the three-day event. 

There were criticisms regarding over-tourism, how much Bezos pays in taxes and his environmental impact.

However there was no mention of the criticism as Sanchez shared details of her wedding with Vogue.

The happy couple got married in a restored amphitheater on the island, as Sánchez wore a high-neck, long sleeve lace Dolce & Gabbana gown that took over 900 hours of atelier to make.

The gown featured a flared skirt, long veil, and a tight-fitting waist, with tons of buttons going up the middle.

‘Very Lauren. Sexy, happy, not too serious, not too drama. Elegant but at the same time sensual,’ Domenico Dolce told the outlet about the bride’s dress.

But the dress wasn’t the only star of the show. The Blue Origin astronaut had many looks for the different occasions, including a pajama-themed party on their last night.

Sanchez chose a strapless, dusty pink bustier Atelier Versace gown for the event, with bejeweled detailing all over the body – but it was her secret accessory that really stood out.

Throughout the weekend, Lauren also wore many custom accessories that were a nod to her new last name, like a black rhinestone-encrusted black clutch bag that read, ‘Mrs. Bezos’ on it in silver gems.

On the morning of her wedding, Sanchez stepped out in a cream, two-piece skirt suit by Dior, adding a personal touch as she wore a brown braided bracelet with diamond charms that read ‘LB,’ in honor of becoming Lauren Bezos.

But Sanchez told Vogue that the wedding wasn’t about the dresses or accessories, it was about finally marrying Bezos, who she described as the love of her life.

‘I’m very happy,’ she told the outlet.

‘More than the dress, I’m happy that I’m getting married and I get to spend my life with my best friend, someone who sees me, someone who adores me, someone who I adore. I am the luckiest woman on the planet,’ she shared.

Days before they walked down the aisle, a source closely connected to the wedding revealed to DailyMail.com exclusively that the couple were already married.

‘They have been married for at least a month, more than a month. The marriage is fully legal and took place in America under American law,’ the insider shared.

They added: ‘When they were planning the wedding, they were clear about the fact that they were already secretly married. There is no application for a wedding license from the couple because it was not required.

‘Whatever happens at the wedding on Friday, it will not be a wedding. Under Italian law, it will not be a wedding celebration, any vows said or rings exchanged will have no legal meaning.’

The source also claimed that Bezos had personally confirmed that he and Sanchez were already legally married, and that they had also signed a pre-nuptial agreement to protect his incredible $244 billion fortune.
