Victoria Beckham has posed naked for a new T-shirt for designer Marc Jacobs as part of a campaign to warn people about skin cancer.

Posh appears completely nude on the T-shirt with only her hands and a strategically-placed caption to cover her modesty.

She says: “Since we moved to California I have realised how important it is to practise safe sun for myself and to keep my three boys’ skin well protected as well.

“Skin cancer is a huge problem and I really wanted to help raise awareness by taking part in Marc’s initiative.”

The tops are signed by Posh and will be available from Marc Jacobs stores from next week.
