The duo smouldered at the camera as they spent some quality time together.
The former Spice Girls singer could be seen sitting in the backseat of a car beside her sister, who is two years her junior.
Showing off their incredible likeness, the siblings adopted a similar pose for the snap.
The 42-year-old donned a monochrome striped ensemble, while Louise sported a black top.
The photo was posted to her Instagram account after the pair had attended the Kent and Curwen fashion show in London.
Beside the capture, Victoria penned: “Love spending time with the most amazing sister and mummy! Love u @louisesadams kisses x VB.”(sic)
The fashion designer’s Instagram followers were clearly delighted with the capture, and rushed to shower the sisters with compliments.
“@victoriabeckham Lovely pic. Lovely sentiment,” wrote one.
Another admirer gushed: “Wow, such beautiful sisters!”
Meanwhile, others couldn’t help but point out the similarities between the two, with one fan writing: “Would definitely say you and your sis looks like twins…. #twinningsisters.”(sic)
Another social media user commented: “You really look alike. Both gorgeous.”
Victoria uploaded another selfie of the sisters on her Instagram story, which she captioned: “Fun day!!! Love u @louiseeadams.”
Earlier that day, the businesswoman had documented her day out at the star-studded event on her social media account.
This picture was liked 897,000 times by her loyal fans, with comments from the couples’ fans saying how much they liked seeing the pair together.
Cynthia Julius said: “Cute as usual.” Eli Semplici added: “Best couple ever.”
It came shortly after a spokesperson hit back after Paddy Power suspended bets on the couple splitting up.
A spokesperson for the betting company had stated: “We’ve decided to suspend betting on the separation between Posh and Becks.
“It looks like it’s a case of 1 becomes 2 with their marriage seemingly going down the loo.”
But, a representative for the Beckhams branded the decision as “embarrassing and laughable”, exclusively to Express.co.uk.
Meanwhile, a spokesperson also told The Sun: “”There is no statement due, no divorce, and a lot of Chinese whispers and fake social media news.
“This is all very bizarre and an embarrassing waste of time.”
