New York, Sep 15 (PTI) Hollywood star Angelina Jolie said her children help her a lot and are her best friends. The 42-year-old actor-director – who has Maddox, 16, Pax, 13, Zahara, 12, Shiloh, 11, and nine-year-old Knox and Vivienne with estranged husband Brad Pitt – has never found a source of support like her brood, and they all get along incredibly well, reported New York Times. “They really help me so much. We’re really such a unit. They’re the best friends I’ve ever had. Nobody in my life has ever stood by me more,” Jolie said. PTI
