Anna Paquin, Stephen Moyer have a baby on the way

Anna Paquin and Stephen Moyer have plenty of heat as an on-and-off fictional couple on “True Blood,” and now the married costars have something to show for it: They’re expecting their first baby.

Paquin and Moyer will welcome a little one come fall, the Ministry confirmed with a rep for the actress.

Oscar winner Anna and Englishman Stephen met on the set of the HBO vampire hit. They wed on the beach in Malibu in 2010. This is the first child for Paquin; Moyer has a boy and a girl from a previous marriage.

Filming for Season 5 of “True Blood” began last November, so chances that we’d see any signs of baby Paquin-Moyer on the small screen are small. Paquin will return as Sookie Stackhouse when the show returns June 10.
