In his airy London studio, David Bailey is hard at work photographing the most popular tenor on the planet. Andrea Bocelli poses quietly, reflectors and flashes creating a light-filled aura around him. His fiancee, Veronica Berti - 25 years his junior and pregnant with their first child (his third) - hovers with an entourage.
The aim is to produce a portrait of the singer for The Official Andrea Bocelli Opus - a project devoted to the singer's life and work, running to more than 800 pages. The book is designed as a luxury collector's item.
With more than 70 million records sold to date, he is truly popular but more as a "crossover" singer than an opera star. His Sacred Arias entered the Guinness Book of Records as the highest-selling solo classical album of all time.
Yet in the classical field, many are still trying to work out the secret of his success. Bocelli's fans don't bother with snobbery: ever since his first album went platinum in 1994, they have bought his discs and flocked to his performances.
But critics are not so kind. He gave a recital at the Metropolitan Opera in New York in February - a programme taken from his latest album, Notte Illuminata - but the New York Times slated his "bland homogeneity" and "dogged, unrelenting quality".
