Angelina Jolie and partner Brad Pitt began proceedings in Vietnam last summer, US-based agency Adoptions From The Heart has revealed.
The average adoption in Vietnam takes sixth months or longer to go through.
A statement from the agency's Vietnam coordinator Heidi Gonzalez reads: "Throughout Ms. Jolie's adoption process, she received no preferential treatment from the Vietnamese government or Adoptions From The Heart."
Gonzalez also hit out at claims by Vietnam's senior adoption official VU Doc Long that the adoption was fast-tracked because of Jolie's celebrity status.
She says, "Contrary to earlier reports, her application was not fast-tracked."
