Harper Beckham will be "devastated" today if her oldest brother Brooklyn fails to wish her a happy birthday, it is said.
Sir David and Lady Beckham's youngest child - and only daughter - is understood to have idolised Brooklyn since she was a young child. Although she doesn't have Instagram yet, it is believed the "family thing" is to tag Harper in a photograph on posts as #harperseven to acknowledge her big day as she turns 14.
But Brooklyn and his wife Nicola Peltz were no-shows at Sir David's 50th birthday celebrations earlier this year, which has led to a public feud within the family. Fearful of a repeat of this episode, a source said: "Brooklyn and Harper used to be inseparable. He adored her, he hopefully still does, but the problem is that Brooklyn has a track record for ignoring family birthdays now.
"It would be devastating for Harper not to hear from him. She hasn't done anything and she's only 13 years old, she is the innocent party here."

The concern has emerged after Nicola, 30, made a number of eyebrow-raising remarks about family life as her own father's birthday celebrations enter a third week. Showing her followers her Pop Mart dolls lined up in a row, she wrote: "our little family", with a telling second snap, which she captioned: "My mom just gets it." She later posted a snap of herself hugging her father, writing: "I love you so much dad."
This has led to the insider's comments Harper will be disappointed if she doesn't hear from Brooklyn, either privately or publicly today. They told Mail Online: "Harper's birthday has always been such a happy day, she's the adored little daughter so it's always so joyous but this is a tough situation. Brooklyn was 12 when Harper was born, he was so important in her life and it must be terribly sad that she isn't seeing him since the fall out with David and Victoria happened."

At the start of her relationship with Brooklyn, Nicola seemed to forge a strong bond with Harper. The actress soon positioned herself as a "big sister" figure to the little girl, who is said to have "adored" her. Harper has reportedly also always been close to Brooklyn, who is 12 years older than her.
But it is believed now the couple, who married in April 2022 at her family's £76million Florida mansion, no longer speak to Sir David and Lady Beckham. Our source said this week Brooklyn's younger siblings, particularly Harper, have sadly become collateral damage of the feud.
"Harper's been particularly affected by what’s going on because she's always been really close to Brooklyn," claimed the source. "They've always had a lovely bond because Brooklyn was that bit older when Harper was born, and the hope when Brooklyn married Nicola was that she'd become like a big sister to Harper in a house full of brothers."
