Jennifer Garner and Ben Affleck have become parents for the third time, welcoming a baby boy, a source tells Us Weekly.  The newest addition to the Affleck family, whose name has yet to be revealed, joins big sisters Violet, 6, and Seraphina, 3.

Announcing her pregnancy in August 2011, Garner, 39, managed to stay mum on the gender of her family’s third baby, and while she admitted she’d be thrilled to have another girl, she said Affleck was excited either way.

Congrats Ben & Jen!!
