Sir Elton John said he has been unable to watch the stage show he wrote the music for due to losing his eyesight. Speaking at the gala performance of The Devil Wears Prada: The Musical he said: "I have lost my sight and I haven't been able to see the performance but I have enjoyed listening to it." The West End show hosted a charity gala for the Elton John AIDS Foundation on Sunday evening.

The star-studded event attracted a host of famous faces including Anna Wintour, Lily Collins and Donatella Versace. The 77-year-old pop star has been in his right eye in July. While his exact condition is unclear, Sir Elton told ABC News' Good Morning America in November that he developed the infection in the south of France.

"It's been four months now since I haven't been able to see, and my left eye is not the greatest," he said at the time. Speaking to the BBC on the red carpet, said she was looking forward to supporting Elton and described the musical as "entertaining". Asked whether the film and musical is at all representative of what the fashion industry is actually like, said it was "for audiences to decide".

"It's for the audience and for the people I work with to decide if there are any similarities between me and Miranda Priestly," she added. It has often been rumoured that the character of Priestly was based loosely on Wintour. The Devil Wears Prada tells the story of an aspirational young journalist, Andy, who become the assistant to one of New York's most infamous fashion mag.
