You read it here first: Prison Break's Sarah Wayne Callies is expecting her first child with husband Josh Winterhalt, the actress' spokeswoman confirms. The baby is due in late summer.

What exactly does this mean for Dr. Sara on PB? I'll have the scoop on that in the coming days, but suffice it to say that Michael's crush will be MIA for at least the early part of any Season 3. (Can you say, "kidnap victim?" Can you?)
