The BEST dressed celebrities at Jeff Bezos and Lauren Sanchez’s star-studded Venice wedding

Billionaire tech mogul Jeff Bezos is finally marrying Lauren Sanchez in Venice today in a lavish $20 million wedding with all of their celebrity friends in attendance.

Their much-awaited nuptials have been dubbed the ‘wedding of a century’ by some, with the 61-year-old Amazon founder – who is one of the world’s richest men – and his bride-to-be, 55, showing off a wide array of designer looks in preparation for the big day.

They kicked off the weekend-long celebrations with a star-studded welcome dinner at the Campo Della Madonna dell’Orto.

The award-winning journalist then made her first appearance of the day when she was spotted leaving the five star Aman Hotel in a ladylike white Dior puff sleeve suit that could hint at her wedding look, paired with a head scarf and oversized sunglasses. She also appeared to show off a brand new enormous diamond ring for the occasion.

The celebrity couple have invited approximately 200 guests for the three-day celebration, including the Kardashians, Sydney Sweeney, and Leonardo DiCaprio.

From royalty to reality stars, here’s who tops the list of stylish wedding guests.

Media mogul Oprah Winfrey, 71, stunned in a pink off-the-shoulder gown, as she showed off her slender figure while leaving Gritti Palace for the evening festivities.

Joshua Kushner’s wife Karlie Kloss showed off her baby bump in an off-the-shoulder black gown and a choker. They’re currently expecting their third child.

He wasn’t the only Kushner in attendance.

Ivanka Trump stepped out with her husband Jared Kushner while wearing a stunning, heavily embellished pink strapless floral gown by Tony Ward, which also featured a thigh-baring slit.

Jordan’s Queen Rania Al Abdullah looked stunning in an elegant wrap and gown in different shades of blue from Armani Privé as she left the St. Regis hotel.

Kris Jenner looked glamorous in a black gown with billowing white sleeves and opted for a much younger hair style to complement the dress.

Khloe Kardashian trailed behind her famous mother in a pink gown, which featured with off-the-shoulder feathered sleeves a plunging neckline.

She accessorized the wedding look with a pair of black sunglasses and a dazzling diamond necklace, along with a slick-back bun.

British singer Ellie Goulding also made an appearance outside the hotel wearing a dark brown sequined dress, as she waved to fans. She boarded the water taxi alongside model Brooks Nader, a close friend of the bride, who donned a draped pink strapless dress with a train.

In line with the apparent theme of the evening, Euphoria star Sydney Sweeney wore pink as well. The strapless dress featured a ruched bodice, as she styled her signature blonde locks with beachy waves.

Prior to Friday’s ceremony, the bride and groom’s A-list guests had opted for more casual ensembles in the lead up to the wedding.

For example, Khloe, 41, wore a $298 Helsa stretch cotton sateen midi while strolling in Italy with her mom Kris.

The conservative dress was a departure from the skintight, bustier animal print dress she first wore when she arrived in Venice. The Good American founder also wore casual Chanel flip flops with gold embellishments as part of the European summer look.

Meanwhile, the Euphoria actress joined Leonardo DiCaprio’s model girlfriend Vittoria Ceretti for a shopping trip Friday morning ahead of the wedding.

She wore a little black dress with a plunging neckline and scarf detailing, paired with Miu Miu’s slingback ballerina flats. Sweeney is model for the brand.

While the pointy-toed, patent leather flats weren’t the right fit for a tourist stomping through the streets, they were perfect for the festivities with their feminine silhouette and edgy buckle.

However, it might not be all smooth sailing for the wedding guests this weekend.

Campaign group No Space For Bezos have already said they plan to disrupt the wedding by blocking canals and have asked activists to ‘turn up with snorkels and masks.’

They have also been encouraged to bring inflatable crocodiles or other toys to scatter along the canals to impede the dozens of water taxis hired to ferry guests between venues.

‘If you can rent Venice for your wedding, you can pay more tax,’ one gigantic banner read in St. Mark’s Square.
