Is it true? From The Daily Mail:
He is perhaps the most famous, or infamous, artist alive. To some a genius, to others a vandal. Always controversial, he inspires admiration and provokes outrage in equal measure.
Since Banksy made his name with his trademark stencil-style 'guerrilla' art in public spaces – on walls in London, Brighton, Bristol and even on the West Bank barrier separating Israelis and Palestinians – his works have sold for hundreds of thousands of pounds.
He has dozens of celebrity collectors including Brad Pitt, Angelina Jolie and Christina Aguilera.
He is also known for his headline-making stunts, such as leaving an inflatable doll dressed as a Guantanamo prisoner in Disneyland, California, and hanging a version of the Mona Lisa – but with a smiley face – in the Louvre, Paris.
But perhaps his most provocative statement, and the one that generates the most publicity, is the fact that Banksy's true identity has always been a jealously guarded secret, known to only a handful of trusted friends.
