“Mad Men” star Vincent Kartheiser and Alexis Bledel, who met when she guest-starred as his character’s clandestine lover on that AMC series and married in June 2014, had their first child several months ago.

Bledel’s representative confirmed to People magazine that the couple had a son, following a comment by Bledel’s “Gilmore Girls” co-star Scott Patterson, 57, to Glamour magazine.

“She hasn’t changed at all,” Patterson said of Bledel, 34. “She looks the same. We’re comparing notes because my son [born July 2014] is about a year-and-a half older than her young son.”

The rep gave no name or other details for the child.
