Ben Affleck is reportedly keen to have another child with and Jennifer Garner to bring their total number of offspring to four. While the actress is content with having three little ones, the actor would like a fourth baby to add to the brood. The duo had toasted their 7th anniversary recently, and the 40-year-old actress, will soon be joining Affleck, in Puerto Rico, where he’ll be filming ‘Runner, Runner.’ “The marriage is rock solid,” Us magazine quoted a friend of Garner as saying. “Jen is happy with three now that she has a boy. Ben wants four,” the friend added. Their third child, Samuel, had arrived in February joining the couple’s two daughters, 6-year-old Violet and 3-year-old Seraphina.
