The “True Blood” co-stars tied the knot in August 2010. This is the first child for Paquin, 29. Moyer, 42, has two children — Lilac and Billy — from previous relationships.

The fifth season of “True Blood,” HBO’s rather sexy supernatural dramedy, premieres June 10. No word on whether a vampire baby will be written into season 6.
