Remember that brief but colorful marriage to Billy Bob Thornton? The matching vials of their blood?

Today, after six children and a loving, stable relationship with Brad Pitt, Angelina Jolie has come a long way from her days as a Hollywood wild child.

"I went through heavy, darker times and I survived them," the Oscar winner, 36, tells 60 Minutes in a show airing Sunday.

"I didn't die young, so I'm very lucky. There are other artists and people who didn't survive certain things."

Asked what those "certain things" were, Jolie declined to go into specifics.

"I think people can imagine that I did the most dangerous and I did the worst, and for many reasons I shouldn't be here," she says. "You think of those too many times where you came close to too many dangerous things, too many chances taken too far."

Still, becoming a mom and an international goodwill ambassador hasn't meant she's lost all her edge.

"I'm still a bad girl. I still have that side of me," she says. "It's just in its place now. ... It belongs to Brad."
