It's a celebratory occasion for exes Ben Affleck and Jennifer Garner, whose youngest is now finally entering his teenage years.
The couple, who were married from 2005 to 2018, welcomed daughter Violet, 19, middle child Fin, 16, and youngest Samuel while together, and now the latter is officially 13, a full-blown teenager.
