Anna Paquin and her “True Blood” co-star husband, Stephen Moyer, are about to add something pretty huge to their packed schedules: raising twins.

Paquin’s reps confirmed recently that she is pregnant with not one but two babies, due in the fall. Funnily enough, Sam Tramell–who plays Sam Merlotte on the show–also has twins. He says he’s been giving the couple some early advice on the ups and downs of raising two kiddos at the same time.

“It’s harder, having twins, but it’s all we know. So we’re trying to impart some decent wisdom,” Trammell said. “I told them to hold on tight!”

Moyer has two children from a previous relationship, but these will be Paquin’s first. No word yet on how “True Blood” producers will deal with the pregnancy, or how Paquin feels about carrying twins with her tiny frame.
