Brad Pitt, while promoting his latest flick, told reporters on Sunday that he and Angelina Jolie are ready for another baby. Pitt’s film is about the wild West outlaw Jesse James, and he appeared for his promotion with Jolie and their collected children by his side. Together, the couple has four children, including 15-month Shiloh, the only one biologically born to the couple. Neither Pitt nor Jolie gave any clues as to whether their fifth child will be adopted or biologically born to them.  Brad Pitt further went on to say he’s quite pleased with fatherhood, though he isn’t getting much sleep.
