Just as we were starting to get all the essentials prepped for our Mad Men premiere party — the final seven episodes begin April 5 on AMC, FYI — we discovered something else to celebrate in the world of Sterling Cooper & Partners. If you think we’re talking about spoilers for these last few episodes, you’re way off because it’s something waaay outside the boardroom. It’s baby news and the newborn’s name is giving us anything but the blues.

Jessica Paré, who plays Don Draper’s wife on the show, gave birth to her first child on Thursday, March 19. Blues Anthony Paré Kastner joins the expanding family of Jessica’s boyfriend, John Kastner, and his daughter, Summer Lee. Considering little Blues’ dad John is a musician, we love the sentimentality of the totally unique musical name, especially for a girl (James Reynolds, you may have just been topped!).

Since we are living in the digital generation, the duo announced the birth of their newborn via John’s Instagram with a snap of Blues being held by his big sister. Who knew so much cuteness could be contained in a square shot.

As if the sibling snap wasn’t already adorable, the couple also used the social media platform to announce their pregnancy. We’re totally not in the age of Mad Men anymore.

If you’re looking to get inspired by the rhythms of a musically-tinged name, may we suggest some bonus names that are sure to be earworms: Harmony, Piper, Harper, Melody, Celeste or Viola. Now get to belting out those names.
