stephen moyer anna paquinAs True Blood's Lafayette might say, "Hooker went and got herself knocked up by a vampire!" Ready for this one, Truebies?

Sookie and Bill are having a baby!

Okay, fine ... not Sookie and Bill, exactly, but off-screen couple Anna Paquin and Stephen Moyer really are expecting their first child together sometime this fall.

Awww! How beautiful is that baby going to be?!

I bet for a second there you thought True Blood was about to get a Renesmee-ish character added to the cast. Which, come to think of it, could very well happen ... and could be awesome! As long as the writers don't name it something like Billkie or Soobillk. (I'm sorry, I still can't get over the Twilight spawn's horrible hybrid moniker!)

Anyway, "sources" say the 29-year-old Paquin and 42-year-old Moyer are "overjoyed" -- Anna "can't wait" to be a mom. Stephen, meanwhile, is already a father of two (son Billy, 12, and daughter Lilac, 10) who'll no doubt make excellent babysitters.

As will Uncle Alexander Skarsgard, of course.

A Bon Temps baby! Let's hope this one doesn't have the same ... uh ... issues as Arlene's baby, Mikey.

Do you think Anna Paquin & Stephen Moyer's baby should guest star on True Blood?
