Brooklyn Beckham isn't just gaining a wife when he ties the knot with Nicola Peltz - as he's marrying into one of the richest families in America.
Posh Spice and Golden Balls' eldest has grown up with superstar parents, but their wealth is dwarfed by the fortune of his billionaire heiress bride-to-be.
Brooklyn and Nicola are getting married at her family's £76 million beach house in Florida - with no expense spared for the extravagant ceremony.
The vibe of the wedding is said to be 'Miami society meets British celebrity' with the star-studded guest list set to include the biggest names from the world of sport and showbiz.
The Beckham family all have their roles to play, with Brooklyn's 10-year-old sister Harper Seven on bridesmaid duties and younger brother Romeo, 19, and Cruz, 17, as the best men.
Becks himself is rumoured to be Master of Ceremonies, while Victoria was reportedly snubbed as wedding dress designer.
The situation is a bit more complicated for Nicola, as she is one of her billionaire father's 10 children.

Nelson, who is currently ranked by Forbes as the 1,729th richest man in the world, has been married three times.
The American businessman, 79, has two children from his first marriage and a whopping eight from his third to 67-year-old former fashion model Claudia Heffner.
The mother of the bride is a keen philanthropist and has an impressive collection of diamond jewellery - and can bond with Victoria over their shared passion for fashion.
Claudia shunned the spotlight after becoming a mother to two daughters and six sons - but three of her kids have become famous in their own right.
Working as a actress, Nicola has appeared in drama Bates Motel and Hollywood blockbuster Transformers: Age of Extinction.
Her brother Will is also in the acting game, having moved to LA in 2009 to pursue a career as a full-time star of the screen.
Will has been in a number of popular TV shows and films, including Netflix hit Sierra Burgess Is A Loser, American comedy Men, Women & Children and horror film Unfriended.
Nicola and Will both have matching Hebrew tattoos on their ribs which read "family".
They also have another brother called Brad who is a professional ice hockey player for the Ottawa Senators, who dad Nelson was once rumoured to have an interest in buying.
There will be an untraditional role for Brad, who will be his sister's 'man of honour' on her wedding day.
"The first time I went to Rome, I brought my mum and my brother Brad, who’s actually my man of honour," the actress revealed to CR Fashion Handbook.
"It is really a beautiful thing to be a part of and it’s very exciting."
However, what roles the rest of her siblings will have during the ceremony is unknown, but it must be a logistical nightmare with nine brothers and sisters to fit in.
"Harper is a bridesmaid for both ceremonies, and the boys will be best men as well - but it's a little complicated," a source explained to heat magazine last year.
"Nicola also has a few brothers, with a big age range, so it's a case of trying to make sure that everyone is included, but without going too OTT."
Last month, Nicola confirmed that her maternal grandmother will be her maid of honour.
She posted a sweet picture of her grandma sitting in a chair smelling a large pink rose with the words: "My Naunni is my maid of honour".
There was also a message from her brother Will which read: "Was w Bunny today and she kept saying how happy and honored she is to be moh [red heart emoji]."
Brooklyn will be spending the night before his wedding with his dad, brothers and Nicola's male relatives.
After a rehearsal dinner on Friday night, the couple will not see each other until she walks down the aisle on the big day.
"[They’re] gonna have like boys slumber party, and then I’m gonna stay with the girls. So from the Friday night dinner, we’re not going to see each other until we get married in the afternoon," Nicola explained on Vogue's YouTube channel.
Brooklyn added: "I'm definitely going to cry. I’m not going to say the song she’s walking down [the aisle to], but when I hear the song, every time, I start to like [tear up]."
Dad Nelson started out driving delivery trucks for his father after dropping out of college.
He is now is non-executive chairman of fast food chain Wendy's, consumer goods business Procter & Gamble, multinational corporation Sysco, and sports business The Madison Square Garden Company.
The Peltz family have a 27-bedroom mansion in Bedford on the outskirts of New York City boasting an ice hockey rink, an art collection and its own lake - with A-list neighbours such as Bruce Willis and Glenn Close.
Their property portfolio also extends to the lavish £76 million beach house in Florida where Brooklyn and Nicola's nuptials are taking place this weekend.
The star-studded guest list includes all of the Spice Girls, Posh's actress pal Eva Longoria and Victoria's Secret model Gigi Hadid.
Also expected in the aisles is celebrity chef Gordan Ramsay, whose family frequently go on holiday with the Beckhams, and Madonna’s son Rocco Richie.
The guest list is also rumoured to include Becks' former Manchester United teammate Phil Neville, his old friend Dave Gardner and American football legend Tom Brady and his wife Gisele Bündchen.
However, one person who won't be at the big ceremony is Brooklyn's godfather, Sir Elton John, because it clashes with his Yellow Brick Road Tour.
