Brad Pitt hinted that he and Angelina Jolie will eventually tie the knot.

"If we feel it's important to our kids, we would," he tells Today show's Ann Curry in a new interview about his Make It Right Foundation project in New Orleans. (See video, above.)

Of his six children, he says, "I'm really proud of this family. I look at my sons and daughters. ... I feel rich being around them. Each one offers so much to the mix."

But Pitt -- who attended the premiere of The Curious Case of Benjamin Button with Jolie in New Orleans on Monday -- says he tries to avoid talking about his kids.

"I just walk away feeling bad about it when I do," he says, adding that what he has to say about the family "seems to get cheapened somehow as it goes through the filter and the airwaves. I just want to keep it close to the chest."

Jolie previously admitted that their children ask them why she and Pitt haven't wed yet.

"Usually people fall in love and everything revolves around the ritual of marriage, children are an afterthought. We did everything backwards," she recently told the Italian edition of Vanity Fair.

"But sooner or later it will be the kids who ask us [to get married]," she added. "You know, they see films and start asking questions. Such as, 'Why are Shrek and Fiona married and you're not?'"
