David and victoria beckham secretly put their mansion up for sale
I'm not aware of any credible sources suggesting that David and Victoria Beckham have secretly put their mansion up for sale. The Beckhams are known for their private nature, and it's unlikely that they would publicly announce such a significant decision without a valid reason.
However, it's worth noting that the Beckhams have been known to make changes to their real estate portfolio over the years. In 2014, they sold their former home in London's Holland Park for £31.5 million. They have also been known to rent properties in Los Angeles, where David plays for the LA Galaxy soccer team.
If the Beckhams were to put their current mansion up for sale, it would likely be a significant news story, and I would expect to see reports from reputable sources such as The Times, The Daily Mail, or other major news outlets.
