If you're Anna Paquin and Stephen Moyer, first comes the HBO show, then love, and then the baby.

Paquin's rep tells CNN that the "True Blood" actress and her husband/co-star Moyer are expecting their first child together.

Paquin, 29, and Moyer, 42, wed in August 2010 in Malibu after meeting on the set of HBO's sexy supernatural series. They're expecting their bundle of joy in the fall.

According to Entertainment Weekly, Moyer has two other children -- Billy, 12, and Lilac, 10 -- from a previous relationship.

Both "True Blood" stars will be back for the show's fifth season when it launches June 10.
