Photographer Rankin has described working with Christina Aguilera as “pure torture”.

Rankin, who has captured the likes of Britney Spears, Kate Moss and the Spice Girls, photographed the Gene In A Bottle singer in 2007.

In an interview with Closer magazine, he revealed Aguilera's demands were so high that she asked her chauffeur to drive her into the studio to avoid being spotted.

"Christina was a diva from hell and pure torture to be around. She's so self-obsessed,” he said.

“She insisted her chauffeur drive her indoors into the studio so she wasn't papped - even though there was nobody outside."

The photographer added: "Then she crashed my after-party and her bodyguard stood outside the bathroom shouting. 'Nobody but Christina uses this toilet!' She's a joke!"

A collection of Rankin's most high-profile pieces is currently on show at The Old Truman Brewery in East London.
