Wife Victoria Beckham also had a special message for her daughter on Instagram, writing: "Happy Birthday baby girl We all love you so much X @davidbeckham @brooklynbeckham kisses from mummy X.” Harper is the youngest of the Beckham’s children and the couple’s only daughter.

The five-year-old has a special bond with her father David and the two are often spotted out and about together, with the 41-year-old playing the doting dad. Speaking to Entertainment Tonight back in 2015, David admitted that he’s more strict with his sons, Brooklyn, 17, Romeo, 13, and Cruz, 11, than he is with Harper.
