True Blood co-stars Anna Paquin and Stephen Moyer welcomed twins today, a bit ahead of schedule. Reps for the actors confirmed to People moments ago that "The babies were born a few weeks early, but are in good health and mom and are overjoyed."

There is no word yet on the names or genders of the bundles of joy, but an announcement is expected as early as today. Paquin and Moyer, who met on the set of their hit HBO series, married in 2010 and Paquin announced that she is expecting twins back in June.

These are the first children for Paquin and the third and fourth for Moyer who has two kids from a previous relationship.
