The usually immaculate star swapped her heels and designer dresses for a bathrobe while showcasing her bed head hair and a makeup-free complexion.
After having time to wake up she soon cheered up when she saw her gifts, with the stand out one being her unique present from daughter Harper, who gave her mum a personalised doll.
The American Girl doll was dressed head to toe in Victoria Beckham's usual style aka a blue shift dress and chic shades, except the dress had a special message.
"my mummy rocks" was written on the personalised doll.
Victoria shared a video of the doll, exclaiming how much she 'loves it'.
The 45-year-old star was spoilt with a stunning arrangement of flowers which covered her kitchen counter, including a huge bouquet from husband David.
Just when you think she's had it all, the fun continued for her 45th celebrations.
She was then treated to breakfast with her family, with David sharing a video of the children singing Happy Birthday to their mum as they dined out.
Instead of a cake, Victoria was presented with a delicious looking doughnut with a candle.
The meals didn't stop there, David also shared videos of the children making icecream for their mother at LA's famous Cold Rolled Ice Cream Company.
Then, later on, the family went for dinner at Giorgio Baldi, an Italian restaurant in Santa Monica, with Brooklyn's model girlfriend Hana Cross joining the fun after also being there for breakfast.
Victoria made an emotional post with a cute caption of a sweet photo of the group posing at their dinner table.
"The most beautiful day with my favourite people in the world xxx I Love u so so so much xxx kisses from a very loved mummy and wife x," Victoria wrote.
David took to Instagram earlier on Wednesday to post a candid portrait of his wife Victoria to mark her 45th and declared she 'deserves to be spoilt' on her special day.
In the beautiful image shows the fashion designer with her iconic chic look, elegantly staring over a table full of candle-lit lamps.
David, 43, captioned the Instagram post, "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.. ♥️."
Meanwhile the kids followed a similar suit, Brooklyn shared a throwback shot of himself as a baby dressed in the football strip of his dad's team Manchester United, with his doting mum, captioning the cute shot: 'Happy birthday mum xx I love you so much x you are the best mum and an amazing woman xx.'
Then Romeo posted a selfie with his mum writing: "Happy birthday to the best mum in the world❤️ I love you so much and hope you have an amazing day @victoriabeckham."
We think it is safe to say Victoria Beckham had an amazing 24 hours with her beloved family, friends and husband!
