However, according to TV Guide, Diane may not be the only pregnant lady on Season 6. "I definitely think there's a very good chance that someone else will be pregnant on the show eventually," executive producer Mike Schur told TV Guide. "Obviously Ann and Chris are actively trying, so that's certainly a possibility for them. Leslie and Ben are very happily married and they're definitely thinking about it based on last year, where they explicitly said they should talk about their family. Andy and April are also happily married."
They were all on our guess list for the big surprise pregnancy from last season's finale. It turned out to be Diane, but now we're back to guessing who else will be preggers. Maybe Leslie and Ben? It would complicate Leslie’s life in creative ways, and also add an edge of jealousy to her friendship with Ann, since Ann wants so much to have a baby.
