Angelina Jolie and her newly adopted son, Pax Thien Jolie, are en route to their home in the United States! 

The three-year-old Vietnamese boy has already had his first photo shoot.  The pictures that will appear in Hello! magazine show Pax playing by a swimming pool with sister Zahara and snuggled up in bed with five-year-old brother Maddox.

"He is a very serious, very sweet little boy. We are slowly beginning to build his trust and bond but it will feel complete only when we are all a family. You can imagine what courage it takes to be in all new surroundings with new people and a new language. He is very strong. It will take him a while to realise he has a family; that his new life is permanent and it won't keep changing," Jolie told Hello!

Upon arriving in the US, Pax will meet his soon-to-be father Brad Pitt and his other sister Shiloh  for the first time. 

Angelina has spent the week in Vietnam where she adopted Pax.  She has come under scrutiny for 'fast tracking' the adoption process using her celebrity status, but adoption officials came to her defense saying she started the adoption process last summer.
