The Beckham clan threw their support behind matriarch Victoria during her Autumn/ Winter 2019 collection showcase, held at London's Tate Britain on Sunday.
And during the presentation, former footballer star David, 43, poked fun at daughter Harper, seven, and Vogue's editor-in-chief Anna Wintour's 'twinning moment', as they rocked similar hairstyles during the runway show.
Following in the footsteps of fashion's leading woman, celebrity offspring Harper bore a striking resemblance to the 69-year-old as she debuted a blunt bob 'do, complete with a freshly cut fringe.
Former Manchester United ace David shared a snap of the pair from the show, with the caption: 'Harper & Anna... who wore it better? Both amazing', alongside a series of heart emojis.
Harper clearly took style tips from her fashion designer mother Victoria, 44, as she sported an all-black ensemble, featuring a turtleneck jumper and skater skirt.
In 2015, David joked that he has categorically banned his ladylove from taking their little girl to a salon.
David told Yahoo Style: 'About a year ago, my wife said, "Maybe we should cut Harper's hair." And I was like, "No! We need to grow it. Do. Not. Touch." Since she was born, we haven't cut it. That's why it's pretty much down to her knees.'
