Angelina Jolie's new movie has been approved by her biggest critics - her children. The actress voices a character in animated film 'Kung Fu Panda', which also features Jack Black, and it has proved to be a hit in her household.

Angelina, whose long-term partner is Brad Pitt, revealed: "Our eldest three, Maddox, Pax, and Zahara, have seen the film and they loved it very much, which is a huge relief because they're my biggest critics." Angelina, who is pregnant with twins, was happy to take on the role because the movie has something to teach children.

She added: "It's nice as a parent to be able to relax and take them to a movie and sit back and think, 'They're going to enjoy this but they're going to get a good life lesson.' "It's always much more exciting to do a film like this when you have children but the truth is I would have done this film if I didn't have children because I think the message is so great." As well as adopted trio Maddox, Pax and Zahara, Angelina and Brad have a 23-month-old biological daughter Shiloh together.
