Angelina Jolie and Brad Pitt regularly fight over politics, because they are both so passionate about their beliefs.
But the actress insists she doesn't mind their frequent verbal tussles - it's what attracted her to Pitt in the first place.
She says, "Brad is political and one of the reasons we came together is that he is very aware. Perhaps he is more outspoken than me, and I like that. It is the only time we argue."
And Jolie reveals that, contrary to her caring and charitable reputation, Pitt is the liberal of the household: "A lot of time is spent arguing over things like justice. I am in favour of a harder line than he is."
