Mark Davis/Getty Images for CCTAMad Men's Kevin Rahm is going to be a dad!
The actor is expecting a baby girl with his wife, cardiothoracic surgeon Amy, he excitedly shared on Twitter.
"Oh yeah... This is happening," the Texas native wrote on Saturday, along with a cute wannabe movie poster of the grinning Rahm's sharing a sweet embrace.
The sweet announcement reads: "Starring together in It's A Girl!" and adds that the bundle of joy is "coming this September."
As the well-wishes poured in, the papa-to-be thanked everyone and added that he is both "excited and terrified."
The couple tied the knot in April 2012 and this will be their first child together.
Rahm is known for his role as Ted Chaough, Jon Hamm's (aka Don Draper) main rival, on the AMC hit series. He also starred as Lee McDermott, the first openly gay neighbor, on Desperate Housewives and Amy Brenneman's cousin Kyle McCarty on Judging Amy.
Congrats to the family!
