Ben has three children with his former partner Jennifer Garner; Violet, Seraphina, and Samuel. Ben still takes time to stay connected to his children, and it's been reported that his kids and Jennifer's kids get along well.
During an interview with TODAY, Jennifer commented on the overlapping of families and said, "We moved in together, the kids moved in together. It's been a really emotional transition but at the same time like all your dreams coming true."
As for whether there are more children in their future, neither Ben nor Jennifer has expressed an interest in having more children together as each has their own.
A source told Hollywood Life that they do not want new children and are past that at this point in their lives. It makes total sense that the two are holding off from welcoming any more kids from here on out, as raising five children is enough of an impressive feat already — with four being teens.
