The former football professional mocked his other half after she was woken up in the early hours of Wednesday morning by their children Brooklyn, 19, Romeo, 16, Cruz, 14 and Harper, seven, to kick off celebrations.
He shared a snap of Victoria looking exhausted as she pouted for the camera.
“When the kids wake you up at 6am on your birthday,” he wrote.
He then jokingly added an animation of a woman falling asleep while holding a cup of tea, for good measure.
David later shared a slew of clips of their children making cold rolled ice cream, with each writing personal birthday messages to their mum.
One clip showed him quizzing Harper on her flavour of choice, mint chocolate chip, before he prompted her to write “I love you daddy” instead.
After enjoying a day with the family David shared a sweet post in tribute to his wife, alongside a candid shot of her surrounded by candles.
He wrote: “Happy Birthday Mama @victoriabeckham ... Have the most amazing day because you deserve to be spoilt by the little ones @brooklynbeckham @romeobeckham @cruzbeckham #HarperSeven & Me of course.”
Victoria also shared a stunning image of the whole Beckham family and Brooklyn’s girlfriend Hana Cross as they dined out.
Overwhelmed by the treats, Victoria wrote: “The most beautiful day with my favourite people in the world xxx I love you so so so much xxx Kisses from a very loved mummy and wife. X”
Stars sent the fashion designer birthday wishes including her fellow Spice Girl Geri Horner, who marked the occasion with a throwback snap from the group’s 2007 tour.
