A man who disguised himself as an old lady in a wheelchair hurled a piece of frosted cake at the Louvre's iconic Mona Lisa on Sunday.

"A visitor simulated a disability in order to use a wheelchair to approach the work, which was installed in a secure display case. The Louvre applied its usual procedures for people with reduced mobility, allowing them to admire this major work of art," a museum statement reads.

Wearing a wig, the would-be vandal smeared the cake across protective glass in front of the painting. A video posted on Twitter shows Louvre security guards walking him out as he shouts a message in French.

"Think of the Earth! There are people who are destroying the Earth! Think about it. Artists tell you: think of the Earth. That's why I did this," he said, according to The Associated Press.

The protective glass was put up after the Renaissance-era artwork by Leonardo da Vinci was damaged in an acid attack during the 1950s.

In 1911, the Mona Lisa was stolen and went missing for two years until someone offered it for sale to an Italian art dealer, who informed authorities.
