Visitors of the Louvre said he threw off his wig and went for the Mona Lisa armed with some sort of cream cake.
Art fans in Paris were stunned as an 'old woman' jumped out of her wheelchair to smear cake over the Mona Lisa.
Luckily, the Leonardo da Vinci painting is protected by bulletproof glass.

People immediately took to social media to describe the bizarre event.
