Angelina Jolie says new tattoo is for Brad Pitt

(CBS) Angelina Jolie has declared her commitment to partner Brad Pitt with some new ink.

The actress added to her famous arm tattoo, which lists the map coordinates of the location where each of her six children were born, with the coordinates of Pitt's birthplace.

Jolie's new ink was on full display Thursday when she stepped out for a photocall for her new movie, "Kung Fu Panda 2," during the Cannes Film Festival while wearing a belted Salvatore Ferragamo beige, chiffon cocktail dress.

She first revealed the tattoo last month during a U.N. goodwill trip to the Tunisia-Libya border, which had fans wondering whether the seventh line meant she was adopting again or having another child with Pitt.

But Jolie set the record straight on Wednesday, explaining to "Extra" that the tattoo was an ode to Pitt, and not a new child.

"Well, if they know that it's latitude and longitude, they would have figured out quickly that it was Brad's birthplace," she said, adding, "It doesn't take much investigation to figure that one out. It's Shawnee, Oklahoma."

Jolie, 35, and Pitt, 47, are expected to hit the red carpet together next Monday for the premiere of Pitt's film, "The Tree of Life."
