Angelina Jolie asked a Santa Monica court to change Pax's last name to Jolie-Pitt. She filed a request on April 16 to add Brad Pitt's surname according to People.

Angelina adopted Pax from Vietnam solo because it is to difficult for unmarried couples to adopt from there. His name became Pax Thien Jolie.

Last year, Jolie asked the same court to change the names of their other adopted children, Maddox and Zahara. There last names are now officially Jolie-Pitt.
