Mad Men might just be starting to wind down, but Jessica has already has her next role locked down: motherhood. The actress, 34, and her boyfriend, welcomed baby boy Blues Anthony Paré Kastner into the world on Thursday. On Friday, the fast-growing family announced his arrival on the proud papa's Instagram with a photo of his daughter, Summer Lee, holding her new baby brother, reports People.
Aww.
Paré, who starred as Megan, Don Draper's wife on the hit series—now in its seventh and final season—kept her pregnancy under wraps until October. Fittingly, Summer Lee starred in that announcement, which occurred over Kastner's Instagram feed with an adorable pic of the trio.
Between his musician dad and a mama with her special style of swing (lest we forget her amazing rendition of "Zhou Bisou Bisou", see below), we're sure the new kiddo will find plenty of rhythm to go with his Blues. We're wishing the whole gang a harmonious segue into family life together.
