BROOKLYN Beckham will have his brothers as best men when he marries next year.
His mum Victoria will design his bride’s dress while his sister Harper, nine, will be chief bridesmaid.
His former England captain dad David, 45, is expected to act as master of ceremonies.
Dates have not yet been set due to Covid uncertainty, but Brooklyn is keen to have Romeo, 18, and Cruz, 15, by his side.
Tonight, a friend said: “Brooklyn is incredibly family focused, just like his parents, and the boys are so close. They are brothers and best mates.
“Although many assumed David would get the gig, there was really never any question of who he would choose to be his best men.
“Coming from such a high profile family, Brooklyn wanted someone he could trust entirely. And that means family.
“We think they will be sharing the role and give a joint speech at the receptions.”
Security at the star-studded summer events will be tight, with armed private teams outside the US service.
Nicola asked Victoria, 46, to design a full-length gown — 18 months after her Studio VB introduced a bridal line — and they have been secretly drawing up designs.
A source said: “Victoria was absolutely delighted — and, of course, unbelievably honoured.
“Nicola is a beautiful girl and will look amazing in anything, but Victoria is famed for her sleek, modern and minimal designs.
“There will be nothing flouncy — Victoria even has a very cool tuxe option.”
This will be Posh’s third high-profile commission. In 2016, she designed a wedding gown for best pal, US actress Eva Longoria.
And two years ago, she was widely lauded after Meghan Markle wore one of her signature dresses on Christmas Day. The navy blue number sold out within days.
Brooklyn’s godfather Sir Elton John may well make a star turn at the piano while Victoria’s Spice Girl pals Emma Bunton, Melanie Chisholm and Geri Horner are all invited — though chances of a reunion performance are put at “slim to anorexic”.
Becks’ best mate Dave Gardner and his Hollywood wife Liv Tyler will be present.
Photographer Brooklyn is likely to call in a favour from one of his high profile contacts — possibly acclaimed snapper Rankin.
The pair worked together last year and Brooklyn is held in “high regard” by the 53-year-old.
Nicola is expected to use make-up from the VB range, and yesterday took to Instagram to plug Posh’s lip liner — receiving 42,000 likes.
Contrary to rumours, US President Donald Trump is not invited to the Stateside soiree, despite his links to Nicola’s billionaire businessman dad Nelson.
And while it is customary for the father of the bride to stump up for the nuptials, it is understood David and Victoria are keen to chip in.
The insider added: “It’s too early for all the micro details, like cake and catering, to have been hammered out. But both families are adamant the wedding will be one to remember.
“One ceremony will be in Florida, where Nicola’s family have their main residence.
“The other is likely to be in the Cotswolds, where Nicola and Brooklyn have spent time together this summer.
“They will likely have a big-name artist performing at the evening do, but nothing has yet been signed off — again, largely because of coronavirus.
“Artists are unable to commit to their own touring schedules. Even Elton is meant to be touring next year.”
The happy couple have been dating for 12 months after first meeting at Coachella festival three years ago.
Romantic Brooklyn proposed with a £150,000 ring he designed himself — but only after asking her dad for his blessing.
Underneath a photo of him embracing Nicola — who was wearing a yellow Victoria Beckham dress — the young influencer wrote: “Two weeks ago I asked my soulmate to marry me and she said yes. I am the luckiest man in the world.”
The photo was taken by Harper, whom Nicola views as an honorary younger sister.
Nicola, who appeared in 2014 movie Transformers: Age Of Extinction, replied: “I can’t wait to spend the rest of my life by your side. I love you so much, baby.”
Victoria quickly chipped in, reposting the snap and telling her 28million Instagram followers: “We could not be happier. Wishing you so much love and a lifetime of happiness.”
Earlier this week, Nicola paid tribute to her beloved late grandmother, and told of her sadness that she would not see her and Brooklyn exchanging vows.
Beneath three photos, she said: “I can’t even put into words how much I miss you being on Earth.
“I wish so badly you could come back to visit me and see me get married. I think about you every day.”
After Brooklyn had a string of less-than-ideal relationships — with one romance with British model Hana Cross infamously culminating in a bust-up at the Cannes film festival — his parents are thrilled he has found his perfect match.
And they know that with a dad worth £1.3billion, and her own stellar acting career, Nicola certainly isn’t after Brooklyn for his money.
Unsurprisingly, the couple are said to have received several “six-figure-plus” offers for magazine deals, both Stateside and here but they have turned them all down.
Two private security firms used by both sets of parents will instead ensure the weddings remain private affairs for family and friends only.
Guests will be politely asked to refrain from posting on social media during the day.
The friend went on: “Brooklyn and Nicola cannot wait to tie the knot.
“While money may be no object, they are adamant it will be an exclusive affair, and despite the apparent scale of the thing, it will actually be pretty intimate.
“When it comes down to it, both Nicola and Brooklyn are just two young, quite shy kids who are madly in love and just want to make everything official.”
