Christina Aguilera,the “diva from hell”?

The snapper,who has photographed celebrities like Britney Spears,Kate Moss and Leonardo DiCaprio,had worked with Aguilera on a photoshoot in 2007.

“Christina was a diva from hell and pure torture to be around. She’s so self-obsessed. She insisted that her chauffeur drive her indoors into the studio so she wasn’t papped (snapped by the paparazzi),even though there was nobody outside.

“Then,she crashed my after party and her bodyguard stood outside the bathroom shouting,’Nobody but Christina uses this toilet.’ She’s a joke,” Rankin told Closer magazine.

Rankin has now vowed not to work with the singer again in future.
