Don Draper probably won't be sending these two a shower gift! Mad Men star Kevin Rahm announced on Twitter that he and his wife Amy Lonkar Rahm were expecting their first child, a baby girl. 

"Oh yeah… This is happening," he tweeted on April 5 along with a photo designed to look like a movie poster. It reads: "Amy Rahm 'The Surgeon' and Kevin Rahm 'The Actor' Starring together in It's a Girl! Coming this September." 

The Desperate Housewives alum married the cardiothoracic surgeon in April 2012, and this will be their first child. 

Rahm played Don Draper's rival Ted Chaough from the ad firm Cutler Gleason and Chaough in 19 episodes of the hit AMC show. He also had a recurring role as Lee McDermott, the first openly gay neighbor on Wisteria Lane on ABC's Desperate Housewives.

As fans and friends took to Twitter to congratulate the daddy-to-be, he thanked them and even admitted, "So excited and terrified."
