Matt Damon, 40, is speaking up for pals Brad Pitt and Angelina Jolie.

The actor told German television station TELE 5 that he's thankful for his privacy, especially because not all of his famous friends have it. Says Damon:

    "I have friends who are like prisoners. Brad Pitt and Angelina Jolie ... They can't just go someplace. If they go for a walk, it turns into an international incident."

Damon says he and wife Luciana are happy to lead a quiet life.

"Ever since I found my wife and we had children, my whole life revolves around that," he says. "I'm really lucky ... I do the work that I love and need, but don't need paramilitary troops to protect me when I walk out my front door."

Matt and Luciana married in 2003; they have four daughters. So, why can Matt -- who's quite an A-lister himself -- lead such a media-free life? He explains after the jump.
