David Beckham has wished his wife Victoria a happy 50th birthday and reflected on her “biggest success” in life – their children.

It comes following the announcement that Harper Collins will publish a story about the couple, known as Posh and Becks, titled The House Of Beckham: Money, Sex And Power, written by former BBC Panorama reporter Tom Bower.

The fashion designer, who found fame in 1990s girl group the Spice Girls, also received online messages from her children – Brooklyn, Cruz and Romeo – as well as her old bandmates Emma Bunton, Melanie Brown, Melanie Chisholm and Geri Horner.

Former England footballer David, 48, wrote on Instagram: “Happy Birthday to my beautiful wife…

“As you head into this birthday you should look back and be proud of what you have accomplished, achieved and what you have built.

“Posh spice, business woman and of course marrying an England captain.

“But your biggest success are your children, you guide them, love them and teach them…

“They love you beyond words, we all love you so much.

“Have a special day you deserve it all 50 and fit.”

The heartfelt message was posted alongside a video comprised of clips showing Victoria through the years.

The fashion designer’s eldest child, Brooklyn, 25, posted a picture to Instagram of the two when he was a baby and said: “Happy birthday mum xx I love you so much x hope you have the most amazing day.”

Elsewhere Romeo, 21, said “thank you for everything” while Cruz, 19, wrote: “Happy birthday mum I love you so much.”

Victoria and David also share 12-year-old daughter, Harper.

Horner marked Beckham’s milestone birthday by sharing a series of photos of them through the years to her Instagram, marking her first social media post since husband Christian faced allegations of “inappropriate behaviour” as a Formula One team principal.

Among the carousel was pictures of them performing on stage and posing for photoshoots from their days in the girl group as Posh and Ginger Spice, as well as a more recent photo of them together.

Horner wrote: “Happy Birthday! @victoriabeckham You’re amazing! From our Tank girl audition over 30 years ago, and you’re still shining bright! Wishing you love & joy.”

Bunton, 48, also known as Baby Spice, also marked the occasion with a video that included clips and photos from her and Victoria’s time in the group.

She said: “Happy birthday @victoriabeckham! 50 and bossing it!

“Your beautiful family are a credit to you and I’m sure you’ll be spoilt rotten. We love you to bits.”

Mel C, otherwise known as Sporty Spice, said she was proud of what the pair had achieved as she posted a selection of photos and videos.

“How did we get here? 50 bloody years old!” she said.

“We have shared so many adventures together from dancing in a church hall in Woking to dancing on top of black cabs at the Olympics!!!

“I’m so proud of everything we achieved together and to watch you go on to fulfill so many of your dreams beyond that is just incredible.

“Happy Birthday Victoria, I am very proud of you, to be your friend and band mate. Love you to bits.”

Mel B, known as Scary Spice in the girl group, also wished Victoria a happy birthday and said: “Hope you have the best day.”

Ahead of her birthday, Victoria said on Instagram that she felt “so incredibly blessed to have reached this milestone” and added that she was grateful for the “unconditional love and support” of husband David.

In 2023 the couples’ life was explored in a four-part Netflix documentary series, which also addressed David’s rise to fame as a footballer and the speculation that he allegedly had an affair while he was playing for Real Madrid in 2003.
