Mad Men star Kevin Rahm has double the reason to celebrate the return of the cult Tv show - his surgeon wife Amy Lonkar is expecting the couple's first child.

The couple announced the news on Twitter.com on Saturday (05Apr14).

The actor, who portrays ad executive Ted Chaough on the show, wrote, "Oh yeah... This is happening,” and created a mock movie poster featuring a photo of the beaming parents-to-be and the tagline, "Starring together in It’s A Girl... coming this September.”

Rahm wed Lonkar in April, 2012.
