The 39-year-old Oscar received her award during a private audience with the Queen at Buckingham Palace on Friday. She was presented with the insignia of an Honorary Dame Grand Cross of the Most Distinguished Order of St Michael and St George.
The presentation comes after Jolie was named in the Diplomatic Service and Overseas Birthday 2014 Honours list. As she's a foreign citizen, she can't be addressed as a Dame - this honorary title has been used instead to give her recognition for her work which includes co-founding the Preventing Sexual Violence Initiative.
Although they weren't photographed, Jolie was accompanied to the palace by her husband Brad Pitt and their children.
"The audience itself between Miss Jolie and the Queen was private," a source told the Daily Mail. "Her Majesty presented her with the insignia in its box. Mr Pitt and the rest of the family were introduced to the Queen afterwards, however."
The news of Jolie's damehood was announced in June at the End Sexual Violence in Conflict global summit in London.
"To receive an honour related to foreign policy means a great deal to me, as it is what I wish to dedicate my working life to," Jolie said at the time. "Working on PVSI and with survivors of rape is an honour in itself. I know that succeeding in our goals will take a lifetime, and I am dedicated to it for all of mine."
Congratulations to Angelina!
