Pax becomes a Jolie-Pitt

The last child that was adopted by Angelina Jolie and Brad Pitt, Pax Thien, now officially has the name Jolie-Pitt.

The Los Angeles Superior Court announced yesterday morning that the Vietnamese boy now shares the name of his famous parents.

Pax is the fourth child of the couple.  Jolie adopted the boy last March from an orphanage.

Jolie and Pitt are also the parents of Maddox, 5, Zahara, 2, and Shiloh, who is the only biological child of the couple, and will soon turn one.
