When Harper Beckham turns 15 on Friday, her parents will inevitably lavish her with gifts and celebrations to mark her special day.But underneath the joy, Sir David and Lady Beckham fear that their only daughter’s birthday will be marred because they can’t give her the one thing she must be hoping for – to be reunited with her eldest brother, Brooklyn.Last year, amid a vicious family feud, he did not send his sister best wishes privately. Instead, there was a public and performative Instagram post.In fact, since his fall-out with his parents, Brooklyn, 27, hasn’t spoken to Harper, to whom he was once so close.’Harper is heartbroken and devastated at her brother’s decision not to speak to her and now her birthday is just days away it becomes a difficult scenario once again,’ says a source.’They were so close. Now he won’t speak to her and she can’t understand why. There is nothing worse for Harper than him ignoring her on her birthday. Harper Beckham will turn 15 on Friday – but her wish to be reunited with older brother Brooklyn does not appear to be on the cards at present Last year, Brooklyn and Nicola both posted an old snap of them with Harper on Instagram as they wished her a happy birthday Since his fall-out with his parents, Brooklyn (second from right) hasn’t spoken to Harper, to whom he was once so closeJoin the discussionShould family disputes ever justify cutting off contact with a younger sibling?What’s your view?’All she wants is to have a relationship with her big brother. It is so horrifying and awful for David and Victoria to see.’Of course, everyone else in the family shows Harper so much love. But for the second year running it’s likely there will be nothing from Brooklyn. It’s not her fault that he is estranged. They’ve never had a cross word.’Last year both Brooklyn and his wife Nicola Peltz, 31, posted on Instagram, using the same photograph of the three of them. But it is understood that they haven’t spoken to her since before the feud erupted on April 25 last year in the run up to David’s 50th birthday celebrations.Brooklyn and Nicola snubbed all of the celebrations.It has been suggested that Brooklyn doesn’t want to speak to his sister as he believes it will put her in a difficult situation. But friends of Posh and Becks debunk that as a ‘stupid and insulting excuse’.Last month, Harper turned up at Brooklyn and Nicola’s house in Beverly Hills alone after her father David received his Hollywood Walk of Fame star just five miles away. Neither was home and she had to leave a letter instead.Harper was photographed by American paparazzi, prompting Brooklyn to later accuse his parents of ‘setting up’ the picture opportunity, something they profusely deny.
