Brad Pitt is spending even more time with his six children. Seven months after Angelina Jolie filed for divorce, a source told ET that the 53-year-old actor had his first overnight stay with Maddox, 15, Shiloh, 10, Pax, 13, Zahara, 12, and 8-year-old twins, Vivienne and Knox. The source adds that the children's nannies were also present during the overnight visit, as was recommended by the family therapist. The source also points out that the reason Jolie, 41, employs the nannies and not Pitt is because she "is the one with sole physical custody of the children?. According to In Touch Magazine, the overnight visit comes just a few weeks after the kids went to Pitt's Los Feliz home on the evening of April 2.
