Meet little Samuel!
Ben Affleck and Jennifer Garner stepped out to celebrate the Fourth of July in Pacific Palisades, Calif., with all three of their kids in tow – providing the first glimpse of their youngest, son Samuel, 4 months.
The couple was joined by daughters Seraphina, 3½, and Violet, 6½, at Wednesday’s patriotic party.
Garner gave birth to Samuel on Feb. 27, and Affleck has since raved about what a wonderful mother she is. In a recent Mother’s Day greeting, the actor called his wife “an incredible, spectacular, world-class mom.”
