The sexy 47-year-old superstar tells USA Weekend:

    "The kids ask about marriage. It's meaning more and more to them. So it's something we've got to look at.”

Earlier this month, X17online was first to report that Brad Pitt and Angelina Jolie are furiously remodeling Miraval -- their 35-bedroom, $60-million estate in the South of France -- in advance of a fall wedding during the grape harvest. A source told X17online exclusively:

    "The couple have been working on the property for a while now because they want to be able to host most of their wedding guests in the house and the home needed to be modernized. But all the locals are talking about how these two will be hosting their wedding here in France, at their chateau, in the fall."

Pitt, who says his kids' safety "keep me up at night," adds:

    “Kids hold up a mirror to you. You can't make excuses. You've got to make sure they've brushed their teeth and eaten a good breakfast. You want to be present if they wake up with a bad dream ... I never knew I was capable of experiencing so much love."
