Is Angelina Jolie having another child with Brad Pitt?

Angelina Jolie, who is in Tunisia doing charity work, appeared with a new tattoo on her left arm.

The 35-year-old actress has coordinates tattooed on her arm marking the birthplaces of her six children. During a visit to refugees at the Tunisia-Libya border, Jolie had a new seventh tattoo.

Could this possibly be a sign that she and Brad Pitt are adding another child to their family?

The other six coordinates mark the birth places of her children. Maddox, who is 9 was born in Cambodia, Pax, who is 7 was born in Vietnam, Zahara, 6, was born in Ethiopia, Shiloh who is 4, was born in Namibia and the 2-year-old twins, Vivienne and Knox were both in France.

In the pictures taken of the actress, it is difficult to see the exact numbers, but the first number of the reportedly new tattoo is 35 degrees north, which according to Wonderwall, who first reported the news, would be Algeria.
