The 33 year old showed off her bump for the first time at the premiere of season two of her new show Mad Men in Los Angeles on Monday . She told reporters, "I'm having a baby." And she revealed her unborn baby will be making its acting debut in another show she has a part in - Big Love. Dudek continues, "The thing is I haven't been that pregnant while I've been working on House or Mad Men or Big Love. But Big Love we're going to be filming for a while and I'm starting to get a little bigger now."
