David and Victoria Beckham are said to be "utterly heartbroken" over their strained relationship with eldest son Brooklyn, who reportedly snubbed his father's 50th birthday celebrations on Saturday.
Insiders claim Brooklyn, 26, did not even call David to wish him a happy birthday.
Sources suggest David is anxious to heal the family rift, but Brooklyn's wife Nicola, 30, is said to be at the centre of the feud.
Brooklyn missed the lavish celebrations in London despite spending the week in the capital, flying back to the US late on Saturday evening.
Instead, David and Victoria celebrated at Core, the three-Michelin-star restaurant in Notting Hill, on Friday night with their three other children and a close circle of friends, according to The Sun on Sunday.
A source said: “Victoria and the family pulled out all the stops but, of course, it’s hard not to think about the one person missing. It’s not just the disrespectful way he and Nicola are behaving, it also impacts the whole family.
“The reality is, Nicola has just driven a huge wedge between them all.
"They’ll always be there for him, but since he’s got together with Nicola — who is very headstrong — this has become quite a toxic pattern of behaviour and at some point you have to say, 'Enough is enough.'"
Another insider added that family members feel Brooklyn has become increasingly remote, and attempts by his grandparents and siblings to bridge the gap have failed.
The Beckhams reportedly enjoy strong relationships with their other sons’ partners—Kim Turnbull, 24, girlfriend of second son Romeo, and Jackie Apostel, 29, partner of youngest son Cruz—but are said to have found actress Nicola "hard work".
Tensions reportedly escalated after Brooklyn and Romeo, 22, stopped speaking, following Romeo's relationship with Kim—who previously dated Brooklyn's friend Rocco Ritchie.
Brooklyn is said to be suspicious of Kim’s reasons for dating Romeo, marking the beginning of the fallout that led to Brooklyn and Nicola skipping his father's milestone celebrations.
Celebrity news website TMZ reports that Romeo and Nicola now refuse to attend any family event where Kim is present.
The silence follows Brooklyn’s absence from Victoria’s birthday last month, when he and wife Nicola Peltz were seen partying at the Coachella music festival. Similarly, neither David nor Victoria posted congratulations online as Brooklyn and Nicola marked their third wedding anniversary.
Despite the tension, the source said there has been “some contact”, and both Brooklyn and Nicola were invited to David’s London birthday party — although they did not respond.
David and Victoria reportedly hired a £40 million Brigadier Global 6000 private jet for his birthday celebrations on Friday, spending the afternoon wine tasting at a vineyard in Bordeaux before dining at his favourite restaurant in Paris. The family later returned to London for a lavish birthday party yesterday.
According to the Mail, the 50th birthday is just the latest of at least 11 family occasions Brooklyn is said to have missed.
