The "True Blood" couple's babies were "born a few weeks early, but are in good health and both Mom and Dad are overjoyed, their rep told People.

The newborns, who have not yet been named by one of television's hottest couples, have already been nicknamed "True Blood twins" in reports. The twins are the first children Paquin, 30, and Moyer, 42, have together.

Moyer has two kids, son Billy, 12 and daughter Lilac, 10, from previous relationships.

The couple wed in August 2010.

"It's always amazing," Mayer reportedly told Zap2it in May. "I love my kids so much. And I think that the fact that Anna is pregnant just adds more crazy to the bundle of fun."

The co-stars recently wrapped the fifth season of HBO's hit show "True Blood."  The season finale aired on Aug. 26.
