Brad Pitt may finally be ready to make an honest woman out of Angelina Jolie.

In an interview with CBS Sunday Morning (airing January 29), the Academy Award nominee says his six children are begging him to propose to In the Land of Blood and Honey director Jolie, 36.

"We're getting a lot of pressure from the kids," Pitt, 48, says. "It means something to them."

Pitt admits he hasn't "been very good" at explaining why he and Jolie have put marriage on hold since first becoming a couple in 2005. "We will someday. We will," Pitt promises. "That's a great idea."

When his brood of six -- Maddox, 10, Pax, 8, Zahara, 7, Shiloh, 5, and Knox and Vivienne, 3 -- asked him to "get mommy a ring," Pitt vowed: "Okay, I will! I will."

The Moneyball and Tree of Life actor adds that he's always been mindful of his children's desires -- especially when it pertains to his busy work schedule.

"You have less time to spend on a project," Pitt explains. "You come home and you're Dad. You're much more conscious of how much time you give to a production."
