"It's always amazing," Moyer told PEOPLE of being a dad again (he has two children – Lilac, 10, and Billy, 12 – from a previous relationship). "I love my kids so much. And the fact that Anna is pregnant just adds more crazy to the bundle of fun."
The Oscar winner is due in the fall. The fifth season of True Blood
premieres June 10 on HBO.
