The couple first struck up their romance after meeting on the set of Mad Men, where Bledel played unhappy housewife Beth Dawes, who was the mistress of Kartheiser's character Pete Campbell. In real life, they went on to secretly marry in a private ceremony in 2014, and in similar fashion, tried to kept 34-year-old Bledel's pregnancy to themselves.
In a possible move to make more room for their little one, the actors sold their one-bedroom, two-bath N.Y.C. penthouse duplex for $1.32 million last month. This is the first child for Bledel and her 37-year-old actor husband.
Congrats to the couple on their new arrival!
