Who's to even say Ai's pregnant/wants kids (just because she likes them doesn't mean she wants them) although I agree it would be cool to have her for a mom.
Lot of people saying everywhere that "omg only a year". Imo this is refreshing after all the shotgun marraiges of only a few months that keeps going on in the entertainment world. :x
Then again she might be pregnant and not tell us until afterwards, but oh well.
