Alexis Bledel and her husband, Mad Men star Vincent Kartheiser, are reportedly expecting their first child although the couple has not confirmed the news just yet.

While attending the Los Angeles premiere of his National Geographic Channel movie Saints & Strangers, well wishers were reportedly seen congratulating him.

“They are expecting but they don’t want a lot of people to know,” a source told Celebuzz. “Only close friends and family know about the baby.”

The couple met on the set of Mad Men when Bledel guest starred as a love interest for his character Pete Campbell. They got married in June 2014 in Ojai, California after getting engaged in March 2013.

“He’s trying to keep it quiet,” the source continued of Kartheiser, “but he’s very happy about the news.”

If the pregnancy news is true, they will either need to get creative or work her pregnancy into the storyline of her upcoming Gilmore Girls revival with Lauren Graham for Netflix.
