When Angelina Jolie and Brad Pitt's children came to visit heron the set of new film Salt, they were flummoxed by her sexy fancydress. So much so that Maddox, eight, had to be informed that theperson in a male naval officer fancy dress costume standing in front of him wasin fact his normally glamorous mother. He reluctantly shook hands with her, but was relieved whenAngelina took off her hat, false nose and fake ears to reveal hertrue self, she said. Once Maddox had been reassured, he and her other five kidsenjoyed playing dress-up with mum's costumes in between takes. "They played with fake blood and they found Mommy very strangein her different hair," Angelina laughed. Back in March, kids in West Virginia were also less thanimpressed by Jamie Oliver's dressing up, CelebriFi reported. The chef wore a pea costume to promote healthy eating in the US,but children at Central City Elementary simply looked bewildered.
