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.
