Cruz Beckham dedicated a song to his younger sister, Harper, during a recent performance in London, marking her 15th birthday. The youngest of the Beckham children celebrated her birthday while the family was in Miami, though her eldest brother, Brooklyn, did not publicly acknowledge the occasion on social media.

David and Victoria Beckham, along with their sons Romeo and Cruz and their respective girlfriends, were in Miami. Cruz, 21, performed with his band, The Breakers, and paused to honor Harper. "We have a special lady in the crowd tonight, my little sister, it's her favourite one of my songs. Harper, I love you!" he announced on stage.

Victoria Beckham shared a series of photos celebrating Harper, writing, "I cannot even begin to express how much I love and adore you and how incredibly proud I am to be your mummy - it has been the greatest joy to see you blossom into a young lady." She included a childhood photo of Harper with Brooklyn, a detail that may have risked further strain in their relationship.

David Beckham also posted a tribute, calling Harper his "Pretty Lady" and the "the perfect daughter." Romeo Beckham shared photos wishing his sister a happy birthday, stating, "I love you so much." Cruz also posted a heartfelt message, writing, "harper i love you more than you know, happy 15th birthday xx." His girlfriend, Jackie Apostel, added her own wishes, calling Harper a "built in bestie."

The family's public displays of affection for Harper contrast with the ongoing reported estrangement from Brooklyn. While in the same country, Brooklyn and Harper have reportedly not spoken. Last month, Harper reportedly visited Brooklyn's home in Beverly Hills after David received a Hollywood Walk of Fame star nearby, but no one was home. She left a letter, which was photographed by paparazzi, leading Brooklyn to allegedly accuse his parents of orchestrating the photo opportunity.

Sources close to the family have described Harper as "heartbroken and devastated" by her older brother's decision not to speak to her. For the second consecutive year, Brooklyn has not publicly acknowledged her birthday. Last year, both Brooklyn and his wife, Nicola Peltz, posted birthday wishes, but it is understood they have not communicated with Harper since the feud reportedly began around April 2024. Friends of the Beckhams have dismissed suggestions that Brooklyn is avoiding his sister to spare her difficulty as "stupid and insulting."

The family is expected to remain in Miami, where David Beckham is a co-owner and president of Inter Miami CF. Romeo was seen enjoying the Miami Beach with his girlfriend Kim Turnbull, while Jackie Apostel wore England team colors in anticipation of a match.
