Design said to represent New Orleans waterway system
Brad Pitt has a strange new tattoo on his lower back – of the New Orleans waterways system.
It is said to show his support for the families devastated by the flooding of the citys levee network by Hurricane Katrina in 2005.
Brad, 44, showed off his latest body artwork while in Monaco.
He already has a series of designs on his skin, including an image of Otzi The Ice Age caveman on his inner left forearm and a Sanskrit Buddhist blessing on his lower back.
Brad also has the birth date of girlfriend Angelina Jolie, 33, written in Khmer on his stomach.
