Angelina Jolie and Brad Pitt

Angelina Jolie finds it "very hard" to protect her children.

The 'Maleficent' star, who raises Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and five-year-old twins Knox and Vivienne with fiancé Brad Pitt, tries not to expose them to films and TV shows with "drugs or nudity," as she doesn't want them to grow up too quickly.

The 38-year-old actress told USA Today newspaper: "It's very hard because the parental controls are so extreme. You wish there was some magic parental control that could just give them enough of the stuff they're excited about and interested in. You know, some crazy skateboarding stunt accidents, and still not be getting access to certain kinds of other things, drugs or nudity. But (those videos) kind of end up in the same category."

Brad and Angelina got engaged in April 2012, but are still no closer to getting married.

She said: "We don't have any plans to get married at the moment. Nothing is organised. Nothing is ready. I don't have a dress. It matters to us in a very private way. But we also understand that we're public people."

Meanwhile, the actress opened up about why she plans to focus on directing in the future.

She explained: "I became an actress because my mom wanted me to become an actress. It took me until my mid-30s to realize I actually didn't. I actually wanted to write and direct and be more involved in politics and humanitarian issues. I'll do a few more films and enjoy it and if I'm blessed to have a good career, but I've never loved it like I love other things."
