Brooklyn, 23, and Nicola, 27, are set to marry at the Peltz family ocean-front mansion in Palm Beach, Florida.

Brooklyn is the oldest son of football legend David Beckham, 46, and former Spice Girl turned fashion designer, Victoria Beckham, 47.

According to The Mail Online, the prenup will protect the Beckhams’ $A660 million fortune, along with the Peltz’s family fortune that towers over this at an estimated $A2 billion.

Nicola is the daughter of esteemed businessman and investor, Nelson Peltz, 79.

A source told the publication: “Nicola flew to Rome with her stylist for wedding dress fittings, and has plumped for two fairytale Valentino numbers.

“Victoria Beckham designed Nicola’s engagement dress, and is fully supportive of the move.

“A VB number is likely to pop up in the evening do.

“Understandably Nicola and Brooklyn want the entire day to be perfect and their attention to detail is quite astonishing,” the source continued.

“Money is obviously no object, but nonetheless they want the day to be a celebration of love, not wealth.”

Reportedly, David Beckham is set to serve as emcee on the night, Brooklyn’s brothers Romeo, 19, and Cruz, 17 are expected to be combined ‘best men’, and Brooklyn’s sister Harper, 10, is one of Nicola’s bridesmaids.

Guests expected to attend are Gordon Ramsay, Eva Longoria, Gigi Hadid, Nicole Richie, members of the Spice Girls, Prince Harry, and Meghan Markle.

The Sussexes rumoured attendance comes after former Spice Girl Mel B confirmed David and Victoria Beckham are inviting their own guests.

The Beckhams are reportedly very close with Meghan and Harry, even attending their 2018 wedding in St George’s Chapel at Windsor Castle.

The Peltz-Beckham Palm Beach wedding will be a short flight from Meghan and Harry’s mansion in Montecito, Santa Barbara.

Brooklyn’s godfather Sir Elton John, 75, will not be in attendance, having to reschedule his Yellow Brick Road tour.

Brooklyn and Nicola became engaged in early 2020, less than a year after they started dating.

He captioned the engagement announcement: “I am the luckiest man in the world. I promise to be the best husband and the best daddy one day. I love you baby.”

The couple is well known for being very public in declaring their love for each other, even sharing with Vogue that they were each other’s plated wisdom teeth on a necklace chain.

The couple is currently living in Beverly Hills in a house they moved into once engaged.
