— -- Alexis Bledel and Vincent Kartheiser are parents.

The actors welcomed a baby boy last fall, Bledel's rep confirmed to ABC News.

This is the first child for the notoriously private couple.

Bledel, 34, and Kartheiser, 37, married in 2014. They first met while filming "Mad Men" in 2012.

"They are such a yin and yang," Kartheiser's "Mad Men" co-star Elisabeth Moss told People magazine in 2013 of the couple. "I've known Vinny for 12 years and Alexis is just the sweetest. I've never seen Vincent like this. It is really cool."
