At 9 p.m. tonight, Modern Family wraps up its third season with “Baby on Board.” Could we witness a new addition to our favorite Modern Family?

We showed you preview pictures here, but in case you missed it, here’s the synopsis:

It’s been an up-and-down emotional roller coaster for Mitch and Cam in their quest to adopt another child. Their latest ride has them bringing Gloria in tow as a translator, leaving Jay and Manny to look after Lily, who has a big dance recital coming up. Meanwhile Claire and Phil have a proud parenting moment when they send Alex off to her first prom, but then that is quickly marred with Haley’s shocking news of her future plans.

Will Mitch and Cam score a son? What will Haley do next year? Let us know your comments before you watch tonight’s episode!
