Hollywood's most popular couple Brad Pitt and Angelina Jolie have heightened the security in their Berlin home in order to make sure that the family is safe from untoward incidents.

This was confirmed after the walls surrounding their Berlin mansion were further raised and the security personnel had been increased as well.

These measures were made to ease the fears of the "Changeling" star who's believed to be in a delicate condition after the birth of the twins.

Pitt is currently filming in Berlin that's why the family is currently residing there.
