Update (September 16, 2014):

And baby makes three! There’s a new cutie in the Mad Men family! AMC star Kevin Rahm and his wife, Amy Rahm, recently welcomed their first child — a baby girl! They took to Twitter on September 13 to share the happy news and the newborn’s first public photo.

“My new favorite Human,” the 43-year-old new papa wrote alongside a snapshot of himself cuddling with his daughter. “Thank you @UCDavisChildren for your amazing staff and excellent care.”

Congratulations to the new parents!

Original story (April 6, 2014):

Sorry, Peggy! Actor Kevin Rahm, who plays Ted Chaough on Mad Men, and his wife Amy Rahm are expecting their first child.

Kevin shared the news in this great tweet on April 5. Their little girl may roll her eyes over it in a few years, but when she's a bit older she'll probably love it.

Kevin, 43, and cardio-thoracic surgeon Amy were married in 2012. In addition to Mad Men, you may know Kevin as Lee on Desperate Housewives or as Jack on I Hate My Teenage Daughter. Hopefully that title wasn't foreshadowing!

Check out Kevin's Twitter timeline if you want to see all the congrats and his responses. It looks like Baby Rahm is in for a fun ride.

Speaking of Mad Men, though, Season 7 premieres on April 13. When we last saw Kevin's Ted, he planned to move his family to California to launch a West Coast office, to distance himself from his mistress, Peggy (Elisabeth Moss).

It marked a win for Ted’s family and now Kevin has a win for his real-life clan too. Congrats, all around! And good luck in Season 7, Peggy.
