Is Angelina Jolie sending a message in ink?
During a U.N. goodwill trip to the Tunisia-Libya border this week, Jolie, 35, was photographed showing a tattoo of a new set of map coordinates on her arm, just underneath tattoos of coordinates of the birthplaces of her six children with Brad Pitt, 47.
First noticed by Wonderwall, the numbers are hard to make out. One possibility is they relate to the North African region Jolie is visiting.
But a source close to Jolie warns not to read too much into her skin art, telling PEOPLE that all adoption speculation is false.
Jolie adopted Maddox, 9, from Cambodia, Pax, 7, from Vietnam and Zahara, 6, from Ethiopia. Shiloh, 4, was born in Namibia and 2-year-old twins Vivienne and Knox were born in France.
