Angelina Jolie & Brad Pitt

Angelina Jolie is doing her old thing. The actress filed a petition Monday April 16th in L.A. County Superior Court to change the name of her latest adopted child from Pax Thien Jolie to Pax Thien Jolie-Pitt.

In court documents obtained by Usmagazine.com it is obvious that Jolie is "the sole adoptive parent of the child" and is requesting the name change "in order that her child's last name will incorporate and be combined with the last name of her partner and be the same as that of her other children."

A hearing will be held on the name change on May 31st at the Santa Monica Courthouse, it has been reported.

Jolie adopted Pax Thien Jolie from a Vietnamese orphanage in March. Shiloh, Maddox and Zahara already share the last names of Jolie and partner Brad Pitt, despite the fact that the couple has not married and say they have no plans to wed.
