haven't ruled out having more children entirely.
"Nothing planned at the moment, but we just don't know. I could end up pregnant," Jolie, 36, tells Marie Claire
in its January issue.
According to the Oscar winner, who recently made her directorial debut with In the Land of Blood and Honey
, the home life she's built with Pitt, 47, has taught her invaluable lessons of selflessness.
"I suppose what I've learned from Brad is to be able to have the kind of family whose happiness and well-being comes before your own," she says in the interview. "I'm very, very grateful to have such a loving family, and I wouldn't have that without him."
And though the couple won't be getting married
anytime soon, Jolie says they already have the strongest bond possible.
"[Brad] has expanded my life in ways I never imagined," she tells Marie Claire
. "We built a family. He is not just the love my life, he is my family. I hold that very dear."
