Entertainment Weekly broke the news on Tuesday that Moyer, 42, and Paquin, 29, are expecting their first child together, due in the fall. The news was confirmed via the couples reps.

The stars, who play Sookie and Bill on the HBO hit, have yet to publically express their excitement over their baby news, but according to E! Online, they are overjoyed and excited about becoming parents to a new baby.

"They have already started telling friends and family," a source told E! "They are so excited and can't wait. Anna is very happy that she is going to be a mom, and Stephen is extremely excited."

Anna Paquin, who is reportedly 12 weeks along, met Stephen Moyer on the set of True Blood in 2007. They tied the knot in Malibu, California in 2010. She had said she wasnt in a rush to have kids with Moyer after marriage.

"I have trouble planning anything more than brunch with my friends," she said. "But when the time's right, we'll do it."

It looks like the right time has come.

This will be Paquin's first child and the third for her husband, who has two other kids, Billy and Lilac, from previous relationships.
