Anna Paquin and Stephen Moyer welcome baby twins!

"The babies were born a few weeks early, but are in good health and both Mom and Dad are overjoyed," said a rep.

The twins are Paquin's first children; Moyer also has a 10-year-old daughter, Lilac, and a son, Billy, 12.

The fifth season of "True Blood" just concluded last month, so the couple -- who married two years ago -- should have plenty of time to enjoy their newborns.

Congratulations to the new family!
