A representative confirmed to E! News that Bledel and husband Vincent Kartheiser (Pete Campbell on "Mad Men"), welcomed their baby in fall 2015.

Turns out co-star Scott Patterson, who plays Luke on "Girls," actually spilled the beans in a new article in Glamour.

When asked what it was like to see Bledel (who was a teenager when the show originally aired) all grown up, he replied, "She's really blossomed as a woman and now she's a proud new mother and married and happy. ... We're comparing notes because my son is about a year and a half older than her young son."

Bledel and Kartheiser are experts at playing the privacy game, though: Their 2014 wedding (they'd met on the set of "Mad Men") was a secret affair. News didn't leak until weeks after it was done.
