"We'd actually like to [get married]" Pitt tells The Hollywood Reporter, "and it seems to mean more and more to our kids."
Pitt, 48, and Jolie, 36, have said in the past that they would only tie the knot when same-sex marriages were legalized. "But I don't think we'll be able to hold out. It means so much to my kids, and they ask a lot," Pitt tells the magazine. "And it means something to me, too, to make that kind of commitment."
Pitt was previously married to Jennifer Aniston for five years before they famously split and he began dating Jolie soon after. They have six children together: Maddox, Zahara, Shiloh, Pax and twins Knox and Vivienne.
When asked if he had popped the question to Jolie, Pitt refused to answer. Whether or not he and Jolie exchange "I dos" sometime in the near future, legalizing same-sex unions is still an important issue to Pitt. "To be in love with someone and be raising a family with someone and want to make that commitment and not be able to is ludicrous, just ludicrous," he said.
Pitt received two Oscar nominations earlier this week — for starring in and producing Best Picture nominated film Moneyball. He may receive a third nomination if he qualifies as a producer on The Tree of Life, which was also nominated for the top prize.
