Another "The Office" star-ah Angela Kinsey (who plays Angela....Martin on the show) showed up at Monday night's premiere of "Walk Hard: The Dewey Cox Story" in all her big(ger)-bellied glory.

The sexy momma-to-be chose this silk striped slip dress from A Pea in the Pod.

"Notes from the Underbelly" star Rachael Harris either really likes the dress or is doing some research for an upcoming episode. (That writers strike has got people pulling from where they can!)
