Angelina Jolie finds being a mother exhausting work.

The Oscar-winning actress - raises six children, Maddox, nine, Pax, seven, Zahara, five, Shiloh, four, and two-year-old twins Knox and Vivienne with partner Brad Pitt - admits having such a large family can be quite hard and she often finds it more relaxing when she's out at work.

She said: "When me or Brad go away and work on films it gives us a bit of a break from the daily routine of being in the house and looking after the kids. You get spoiled on a film set and in some ways it's easier to be working long hours on a movie than taking care of a large family just because you do get very tired at the end of the day.

"I felt that way especially after the twins were born because the demands on your time are so great. It meant that Brad had to spend a lot more time with the other kids because mommy was too busy or tired."

Although Angelina often finds being a mother-of-six exhausting, she knows how lucky she is to still have a successful career and the support of Brad.

She added to Britain's Hello! magazine: "I'm very grateful to be in a position where I can still work and enjoy that creative part of my life and not feel like I'm neglecting my responsibilities as a mother. I also love having a man like Brad who enjoys looking after the kids the way he does, because it's a lot of work."
