Pitt and Jolie have tough time in son's school

London : Parents of children attending the same school as Angelina Jolie and Brad Pitt's adopted son Maddox have been asked to respect their privacy.

In a letter, the parents have been asked to stop asking the couple for autographs as they come to drop and pick up the kids, reports contactmusic.com

The letter by the school's director of operations reads, "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 child (ren), I must ask for everyone to please respect the family's privacy and discontinue these practices."

The director added: "I want to make you aware that before the first day of school, I met with their security team to discuss the best manner for them to drop off and pick up their son. Our foremost goal was to cause the least amount of disruption to the school and to ensure the security of all of our students and families."
