"I'm having a baby!" she gushed to PEOPLE after showcasing the new addition for flashing photographers on the red carpet.
This will be the first child for Dudek, who's married to painter Matthew Heller. She said she's just under five months and feeling "great," adding, "Cheese and sleeping, that's my life these days."
Dudek, 33, played Robert Sean Leonard's love interest on House last season but was killed off in a freak bus accident. She's still very much alive as the nosy neighbor on Mad Men, as well as on HBO's Big Love, where she plays a Lady Macbeth-like wife to polygamist villain Alby Grant.
"The thing is I haven't been that pregnant while I've been working on House or Mad Men or Big Love," she said. "But Big Love we're going to be filming for a while and I'm starting to get a little bigger now – but all those polygamist women are pregnant all the time anyway!"
