Jeff Bezos and Lauren Sánchez reportedly hosting pajama party

Guests at Lauren Sánchez and Jeff Bezos’ wedding week will be jammed packed with three different theme parties.

The bride-to-be, 55, and groom, 61, are reportedly planning a pajama party in the days leading up to their massive Italian wedding, according to TMZ.

A source told the outlet Monday. “Guests will need clothes, outfits and accessories for a wide range of events.”

The outlet added that the wedding — which will reportedly be on the billionaire’s massive boat — is likely to include cocktail parties, a rehearsal dinner, and a reception.

Guests including Oprah Winfrey, Barbra Streisand, Ivanka Trump, Orlando Bloom, and more are said to have been invited to the multi-day bash.

The report comes as protestors gather in Venice, where the wedding festivities are set take place, to push back on the Amazon founder’s massive celebration of love.

International environmental group Greenpeace unfurled a huge banner in St. Mark’s Square, reading, “If you can rent Venice for your wedding you can pay more tax.” The banner included a photo of Bezos laughing.

The group took to Instagram Monday to share a clip of its members spreading out the banner in the square.

“Jeff Bezos pays his staff poverty wages and dodges tax,” they captioned the video. “No wonder he can afford to shut down half of Venice for his wedding this week. Tax billionaires NOW.”

Italian protestors operating under the name “No space for Bezos” have also been distributing posters throughout the city with slogans including “Veniceland: A playground fit for an oligarch.”

High-end event planners Lanza & Baucina Limited came to the defense of the couple amid backlash over the high-profile nuptials.

“From the outset, instructions from our client and our own guiding principles were abundantly clear: the minimising of any disruption to the city, the respect for its residents and institutions and the overwhelming employment of locals in the crafting of the events,” they said in a statement of the star-studded event.

The couple, meanwhile, quietly donated to local charities ahead of their lavish wedding celebration, a source recently told Page Six.

The reported themed parties aren’t the first celebrating the impending union of Bezos and the former journalist.

Sánchez hosted a star-studded, multi-day bachelorette party in Paris in May attended by Kim Kardashian, Kris Jenner, Eva Longoria, and Katy Perry, among others.

The bride-to-be kicked off the festivities with an epic dinner outing at Lafayette’s Paris restaurant on May 15, followed by a luncheon and a boat party on May 16.
