It’s not often that the Beckham family are B-listers. But this weekend, when their son marries into real money, the celebs’ estimated $500 million fortune will look like chump change. (Yes, there reportedly is a prenup.)

Brooklyn Beckham — the 23-year-old aspiring chef son of Victoria and David Beckham — and “Transformers: Age of Extinction” actress Nicola Peltz, 27, are set to wed Saturday at her family’s $123 million, 44,000-square-foot oceanfront mansion, Montsorrel, in Palm Beach, Fla.

Peltz’s father, investor Nelson Peltz of Trian Fund Management, is said to be worth $1.7 billion.

On the guestlist for the “influence-heir” affair are Victoria’s Spice Girl bandmates — Mel B, Mel C, Emma Bunton and Geri Horner (nee Halliwell) — as well as Eva Longoria, Rocco Ritchie, chef Gordon Ramsay and his family, Gigi Hadid, Nicole Richie, Elizabeth Hurley, sports agent Dave Gardner (though likely without Liv Tyler, from whom he split last year) and Tom Brady and Gisele Bündchen.

Brooklyn’s godfather Elton John reportedly can’t make the festivities because he’s on tour.

While there has been speculation about Prince Harry and Meghan Markle — after all, David and Victoria were at their 2018 royal nuptials — showing up, an inside source told Page Six that they will not. Too bad, as they could have crashed at one of the Peltz family’s nearby properties, like the cozy 18,000-square-feet house across the street from Montsorrel.

According to a Beckham source, they might not be missed: “No way will the respective families be impressed to be upstaged by exiled royalty.”

Snoop Dogg has said he’ll be DJ’ing at the after-ceremony festivities.

“Brooklyn’s wedding is going to be a big affair and my gift to him and his wife-to-be is I will come down and do a set for them on their big day,” the rapper, who is pals with David, told The Mirror.

But don’t expect a Spice Girls reunion, said the Beckham source. “We’ve heard that so many times before for famous occasions and it never happens.”

Brooklyn’s brothers, Romeo, 1, and Cruz, 17, are reportedly his best men. Nicola’s 3-year-old grandmother will serve as her maid of honor and her brother Brad, a former AHL hockey player, as man of honor. Brooklyn’s sister, 10-year-old Harper, is expected to be a bridesmaid. David is expected to be the master of ceremonies — and has a big surprise planned.

“He is taking his duties very seriously and keeping the surprise under wraps,” a close source told Page Six. “Brooklyn’s friends are joking that the surprise is that Inter Miami, the MLS  soccer club [which David owns], will actually win a game!”

According to the close source, several of Brooklyn’s friends from home aren’t going to be there but will attend a London reception planned for next month. They are said to like Nicola. “She’s surprisingly down to earth given her family’s wealth, and they are very nice together,” the close source said. “But we do call her Peltz Spice behind her back.”

While Nicola wore a dress from Victoria Beckham’s fashion line for her engagement photos, she’s gone high couture for her wedding gown. Nicola told CR Fashionbook that said she is wearing a custom Valentino wedding dress, among several Valentino outfit changes.

The close source told Page Six that “Victoria was asked to design the wedding dress — she designed her pal Eva Longoria’s wedding dress — but apparently her fashion brand no longer does bridal wear so she was happy for Valentino to take the honors. She gets nervous enough anyway at stuff like this without the extra burden of being responsible for the dress.”

Nicola asked Leslie Fremar, a longtime friend who also styles Hollywood A-listers like Demi Moore and Charlize Theron, to help her look her best. They flew to Rome twice to work with Valentino designer Pierpaolo Piccioli at his atelier.

An inside source told Page Six that either US or British Vogue will cover the affair.

The lavish affair is being orchestrated by Claudia Peltz, the glamorous mother of the bride. Guests will most likely be dining on gourmet creations by French chef Thierry Isambert, whose catering truck has been spotted at the Peltz compound. The eponymous caterer is one of South Florida’s most prestigious chefs, with clients including Dior, Fendi, Neiman Marcus, MTV and the Miami Heat. His cuisine is described as “highly structured creations, based on classic 17th century European recipes, infused with a blend of Mediterranean, Caribbean and Pacific influences.”

Grand tents have already popped up on the Peltz’s oceanfront-facing backyard. For the ceremony, Brooklyn and Nicola are said to be incorporating several Jewish traditions into the wedding, including marrying under a chuppah and, reportedly, signing a ketubah, or marriage contract.

Both families have ties to Judaism: Nelson Peltz is Jewish and raised his eight children with Claudia in the Jewish faith in Mount Kisco, NY. In 2016, he threw a lavish bar mitzvah — complete with a hockey rink — for his twin sons, Zachary and Gregory, at the Pierre Hotel in New York City, costing an estimated $2 million.

David’s maternal grandfather, Joseph West, was Jewish, too, and the former soccer star wrote in his autobiography how he “used to wear the traditional skullcaps when I was younger and I also went along to some Jewish weddings with my grandfather.”

A source told The Mirror that David wants to recite one of the Hebrew blessings at the wedding.

In Palm Beach, Nelson and Claudia belong to Temple Emanu-el, although the synagogue’s rabbi, Michael Resnick, wasn’t asked to perform the ceremony.

“I would have loved to marry them,” Resnick told The Post. “I’m from LA, so I don’t get starstruck.”

He divulged that the Peltzes are fairly new members and guessed that they would most likely fly in a rabbi from New York to officiate. The synagogue’s newsletter shows
that Nelson and Claudia are Shromrim (Guardian) level donors, which is the highest level.

Nicola even has a tattoo that says “Family First” in Hebrew. She and Brooklyn, meanwhile, have matching butterfly tattoos, and Nicola inked Brooklyn’s name in cursive on her upper back. He has at least five tattoos dedicated to her. The couple also wear each other’s gold-dipped wisdom teeth on necklaces.

The bride has been primping for the wedding all week. Masseuse to the stars (including Ariana Grande, Hailey Bieber and Jennifer Aniston) Rebecca Faria flew in from Beverly Hills to administer her famous Detox massage, which starts at $350 and promises to “stimulate metabolism, treat cellulite and reduce inches by eliminating toxins and water weight from the body.”

Swiss aesthetician Lena Bratschi of Carasoin Day Spa also arrived from LA to deliver some facial time.

Meanwhile, the Beckhams have been enjoying a family vacation in nearby Miami, dividing time between David and Victoria’s $20 million penthouse at One Thousand Museum and their $6.6 million yacht, Seven (also daughter Harper’s middle name and David’s old jersey number). The boat has reportedly moved to Palm Beach for the wedding.

On Tuesday, the family attended Romeo’s soccer match. The 1-year-old — who will have model girlfriend Mia Regan on his arm for the wedding — plays for Fort Lauderdale CF, Inter Miami’s reserve team, which is owned by David.

It’s reported that Brooklyn and Nicola, who were first linked together at a 201 Halloween party, are moving to Miami after having sold their $11 million Los Angeles home.

Her acting career seems to have petered out a bit after appearing in the “Transformers” franchise in 2014 and the A&E series “Bates Motel” in 2013. Nicola had a co-starring role in the Netflix film “Holidate” in 2020, and more recently wrote, directed and starred in a movie called “Lola James,” alongside Oscar nominee Virginia Madsen. No release date has been set yet.

Brooklyn, meanwhile, has dreams of being a “great chef” by filming his Facebook and Instagram series “Cookin’ With Brooklyn” — which, as The Post reported, required a team of 62 professionals to help him demonstrate how to make a sandwich.

As one source put it, and not in a complimentary way: “He is to cooking what [his mother] Posh was to singing.”
