Is Angelina Jolie adopting baby No.7

During Angelina Jolie’s visit to the African country of Tunisia on Tuesday, sharp-eyed observers noticed that she added another geographic coordinate to her growing list of latitudes and longitudes representing the birthplaces of her six children.

So does coordinate number seven signify a new addition to the Jolie-Pitt clan?

Angelina Jolie told Larry King in December that she and Brad Pitt are "always open" to adopting another child.

Gossip site Wonderwall noted that only the first number on the bottom line of the coordinate is legible: 35 degrees north–which could be Algeria, a country the Jolie-Pitts have yet to adopt from.

Or, it could be the coordinate for Oklahoma–Brad Pitt’s birthplace.

"She got the seventh line right around the time she and Brad moved the kids back to L.A. It signifies family unity,” a source tells In Touch.

Another source told People magazine that the new adoption rumors are untrue, but did not explain the significance of the tattoo.

Jolie, a United Nations goodwill ambassador, was in Tunisia to urge support for refugees who fled the violence and political unrest in neighboring Libya.

According to the Office of the United Nations High Commissioner for Refugees, the Jolie-Pitt Foundation paid the airfare for 177 people to fly back to their homelands and donated an ambulance to help aid injured refugees in Tunisia.

"The international community has done well to reinforce Tunisia's remarkable relief effort," Jolie said in a statement. "But with 2,000 people still crossing each day, we cannot let the funding dry up and need to sustain the momentum."

Jolie did not release a statement about her new tattoo.
