Ambassador Angelina Jolie is in Tunisia doing charity work — and also keeping a big secret, it seems. Upon closer inspection of the tattoos on her left arm, which bear the global coordinates of the birthplaces of her six children with partner Brad Pitt, it’s clear that a seventh line of coordinates has been added. The seventh line of coordinates on Jolie’s arm begin with the latitude N 35 degrees 10 minutes 44 seconds, but the longitude coordinates are obscured. Interestingly, latitude parallel 35 degrees north passes through Tunisia. Jolie’s manager Geyer Kosinski has not yet responded to a request for comment about the new tattoo.If history serves correctly, it would mean that Jolie and Pitt have adopted another child, but so far there is no word about whether the child is from Tunisia, when they were adopted or their age/sex. Could Maddox, Pax, Zahara, Shiloh, Knox and Vivienne have a new brother or sister?! We’ll be sure to keep a close eye on that ink!
