Staff at the school have sent out a letter to parents, warning them to stop mobbing the besieged megastars.
The letter is reported to have said: "Regretfully, I have seen some parents taking pictures, asking for autographs, talking to the media and even shouting at Ms. Jolie and Mr. Pitt for recognition.
"Therefore, in the best interests of the school and safety of your children I must ask for everyone to please respect the family’s privacy and discontinue these practices."
Angie and Brad are now said to have agreed to stagger the times that they bring little Maddox to school, in a bid to prevent further chaos from breaking out in the schoolyard.
