Despite starting a family with Brad Pitt, the actress doesn't want to become his wife.
Angelina Jolie told Reader's Digest magazine: "We've both been married before. Our focus when we got together was family, and we are legally bound to our children. That really seems to be the most important thing."
The 'Tomb Raider' star has been married twice before, to British actor Jonny Lee Miller and Billy Bob Thornton, while Brad was previously married to Jennifer Aniston.
The 31-year-old also revealed she and Brad have to sneak off to the bedroom every chance they get to spend some time alone, away from their four children.
