Oh, Baby! Who's Pregnant on Brothers & Sisters?

The latest scoop on what lies ahead on the ABC hit and why your jaw will be left hanging

Finally, some happy tears to be shed on ABC's Brothers & Sisters.

Sources tell me that along with a wedding, an extended hot French romance (Gilles Marini, anyone?) and a homecoming for Balthazar Getty and his so-much-better half Sarah Jane Morris, a huge pregnancy surprise is in the works.

So who is the mama to be?

I can rule out one Walker for you: It's not Sally Field. I know...Now you're really thrown!

And though Kevin and Scotty will move forward with their surrogacy plans, this has nothing to do with that.

More clues: Gilles Marini's 12-pack abs were just awarded an extra four episodes, slated to begin in January.

So could Sara (Rachel Griffiths) have a hot, half-French bun in the oven? (An adorable mini croissant, if you will?)

Or maybe Kitty will have a miracle baby? Julia a baby by another daddy? Or perhaps Justin and Rebecca's recently seen "study break" was more productive then they thought?
