ROMEO Beckham's milestone 18th birthday was an intimate affair with his family at their sprawling Cotswolds estate.
The aspiring football was spoilt with a rainbow cake while surrounded by his immediate family.
Mum Victoria Beckham gave fans a behind the scenes look at the teenager's festivities.
Videos on her Instagram stories showed Romeo with his blonde hair tied back and wearing a white hoodie while blowing out his birthday candles.
The long gold candles sat atop a white frosted cake covered in colourful sprinkles and read in red writing, Happy Birthday Romeo xx.
He then carefully cut his cake to reveal the rainbow filling.
Romeo posed for a series of photos alongside the table with his cake and country flowers underneath canvas bunting that read 'Happy Birthday'.
He smiled in photos with both sets of grandparents, Victoria's parents, Jackie and Anthony Adams, followed by pics with dad David's dad, Ted and his fiancé Hilary Meredith.
Finally, he smiled alongside his siblings Brooklyn, 21, Cruz, 15 and Harper, nine and David's mum, Sandra.
Victoria captioned a photo of her children: "Happy birthday @romeobeckham X kisses on your birthday!! Love u so much."
The intimate insight into Romeo's birthday after his dad, David, posted an emotional tribute to his son.
The football ace, 45, posted a slew of unseen family photos alongside a sweet message to his "little man" to celebrate the milestone day.
David shared a video of family snapshots to the tune of 4 Seasons of Loneliness by Boyz II Men - which he revealed is the song Romeo was born to.
The snaps showed him cradling a baby Romeo, his son pulling funny faces with his siblings and having his first shave.
The cute montage ended with a video of a shirtless David standing shoulder to shoulder with Romeo and admitting reluctantly to the camera that the teen is "slightly taller" than him.
Ex-England captain David wrote alongside the clip: "Happy 18th to my little man ( or not so little anymore ) 🤨
"You have grown into the most beautiful person and that as you say yourself ( is a man finally ) 🤔 we love you so much never give up on your dreams & goals."
The father-of-four went on: "This shows from day one in my arms with the song you were born to up until our latest moment where yes I had to finally admit my son is taller than me 😩
"Happy Birthday mate @romeobeckham @victoriabeckham @brooklynbeckham @cruzbeckham #HarperSeven ♥️."
Romeo clearly appreciated his dad's efforts and replied sweetly: "Love you dad."
David wasn't the only one to mark the big day - Brooklyn told his brother: "Happy 18th birthday Romeo x you are amazing and I hope you have the most amazing day ❤️ I love you so much."
