Whats with all the celebs popp'n babies at the same time?

i try not to pay attention, but jamie lynn is unavoidable, then i saw Christina Agulara, and is Nicole Richie pregnant? is it just me, every time i get a glimpse of the celebrity life i see another big belly. is this a fad? is being pregnant like a fad now? and you know Brittney spears always has somthing in the oven, probably brain-damaged floating around in a sea of alcohol. i don't even hate her...i just feel bad...she has issues, thank god for dr.phill though, right?(sarcasm)
