Kate Moss has recently completed work on a short film directed by Mike Figgis.

Conducted in conditions of extreme secrecy, the shoot, for lingerie company Agent Provocateur, took place last month in a private house in Mayfair; the film will be marketed later this year as if it were an internet viral video.

Figgis also took 40 still photographs for the Agent Provocateur catalogue. The director, who had not worked with Moss before, told a friend: "I finally realise why people call her a supermodel. She is the only one and the best."

Agent Provocateur's owner, Vivienne Westwood's son Joe Corre, would only hint at the nature of the forthcoming ad campaign. "Watch out for something in September that is huge," he told me, "but top secret for now." Figgis's office, meanwhile, claimed to know nothing about the campaign.

Moss has also been splashing out on art, recently buying a sculpture called To Every Seed His Own Body by fine-art taxidermist Polly Morgan. Moss paid ￡4,000 for the piece - a stuffed blue-tit in a bell jar - and plans to use it to brighten up her Cotswolds home.
