Elaine pregnant on 3/13 episode

Did anyone else notice how clearly pregnant Julia Louis-Dreyfus appeared on the 3/13 episode? Despite usually appearing behind desks, etc., there were a few times (like when she was talking with her women friends in front of the theater) where her midsection was clearly visible and she is obviously pregnant. I think the writers are deliberately being not-too-careful about hiding the fact, while everybody completely ignores it. Much better than if they had incorporated a baby into the story line, IMHO.
