"Happy Birthday @RomeoBeckham," Victoria wrote on Instagram alongside a video montage of Romeo throughout the years. "The sweetest, kindest and most generous soul. We are so proud of you and we love you more than words can express, you are our everything xx Kisses."
The soccer player shared the same video to his page, writing, "Happy 21st Birthday to my little man. Dad is so proud of the person that you have become, kind , generous and passionate about what you love , keep being you and dream big. we love u so much x."
The video opened up with a young Romeo sporting a Real Madrid soccer jersey—David's former team—and getting ready to kick a ball. His dad can be heard asking, "Romeo Beckham, are you ready?" to which the smiling youngster responds, "Yes I am."
A compilation of photos and videos of Romeo showed him on the soccer field, on vacation with his family and cooking up a storm in the kitchen.
Romeo's siblings Brooklyn, 24, Cruz, 18, and Harper, 12, also appeared in the montage, along with Romeo's girlfriend Mia Regan.
The tight-knit crew is often giving one another assists on their posts, whether that be either in defense or taking a shot.
Take Romeo's bleach blonde hairdo for example. Back in 2021, the young athlete posted a snap of himself with the new look, to which the retired midfielder chirped, "Nice hair @romeobeckham I wonder where u got that idea from."
But the hair style wasn't a rookie move on Romeo's part, in fact he has followed in his dad's footsteps in more ways than one. In January, he made his debut for Premier League Brentford's B team, and David was on the sidelines cheering him on for the first game at Welling United's Park View Road Stadium in England.
Documenting the moment, Romeo wrote on Instagram at the time, "Happy to make my debut @brentfordbteam and get the win."
