People magazine reports that Garner has given birth to the Hollywood couple’s newest addition and first boy. His name has not been released yet.

The son of Garner and Affleck, both 39, joins older sisters Violet, 6, and Seraphina, 3.

The director of “The Town” and the “Juno” star began dating in 2004 and married in 2005. They first appeared on screen together in “Daredevil,” a film that was not nearly as successful as the couple’s marriage and family life appears to have been so far.

Garner will be seen on screen next in the butter sculpting comedy appropriately titled “Butter,” while Affleck is in post-production on his next directorial effort, “Argo.”
