Harper Beckham is preparing for her upcoming 14th birthday – with a dark cloud on the horizon.

Her parents are deeply worried her big brother Brooklyn won’t be in touch to send his best wishes amid the rift that has torn the family apart.

It comes after Brooklyn, 26, shunned all of his father’s recent 50th birthday celebrations.

Sir David and Victoria – who is now Lady Beckham, aged 51 – were very upset when their oldest son and his wife Nicola Peltz neglected to reach out to Harper during their visit to London for a photoshoot with the French-Italian brand Moncler last month.

Now they are said to be worried the same thing will happen on Harper’s big day, July 10.

‘Brooklyn and Harper used to be so close,’ reveals a source. ‘He cherished her and hopefully still does, but the issue now is that Brooklyn has a habit of missing family birthdays these days.’

‘It would be devastating for Harper not to hear from him. She hasn’t done anything and she’s only 13-years-old.

‘David and Victoria very much blame Nicola for all of this but hopefully Brooklyn will see sense.

‘While Harper doesn’t have her own Instagram yet, the family thing is to tag her in on their posts as #harperseven.’ 

Influencer Brooklyn and Ms Peltz, 30, no longer speak to Sir David and Lady Beckham, with the couple believing that she controls Brooklyn.

Before the family fall-out, Ms Peltz would post on social media that Harper was her little sister.

Beckham sources say that this was all part of a move to ‘make Nicola look good’.

Brooklyn gave his parents hope that he won’t shun Harper when he wished his grandmother Sandra, Sir David’s mum, a happy birthday via Instagram amid the fall-out with his parents.

It was the first time Brooklyn had acknowledged any of his family on social media since the squabble deteriorated last month after he and Ms Peltz snubbed all of Sir David’s 50th birthday celebrations.

Sharing a throwback picture of himself and grandmother Sandra, Brooklyn wrote in a caption: ‘Happy birthday nanny xx love you so much.’ The post came two days after Brooklyn marked the 83rd birthday of his father-in-law, US billionaire businessman Nelson Peltz.

As well as snubbing his father’s milestone, Brooklyn didn’t wish Lady Beckham a happy birthday when she turned 51 in April, nor her father Tony Adams on his big day in May.

Brooklyn also failed to toast his parents on Mother’s Day and Father’s Day this year.
