Stormy Future for 'Peaceful Sky' Jolie?

JOLIE BAGS PAX Angelina, son

The celebrity child formerly known as Pham Quang has arrived!

He'll be known as Pax Thien now—that's the Latin Pax, meaning "peace" and Vietnamese Thien, meaning "sky." As crunchy-cool as it might sound, child psychology experts aren't sure Earth Mother Ange's decision to rebrand her three-year-old is wise.

Dr. Laura Schlessinger tells Radar that, although the name change might not cause "significant trauma"—not like, say, uprooting Pax from his native country to live with unmarried, movie star parents—the rebranding is baffling. "I don't understand changing his first name when he already identifies with it," Schlessinger says.
