Hollywood couple Anna Paquin and Stephen Moyer have become parents to twins.

The True Blood co-stars, who wed in August, 2010, received an extra special anniversary present this summer when the babies were born prematurely.

A representative for the pair tells People.com, "We can confirm that Anna Paquin and Stephen Moyer recently welcomed their twins into the world. The babies were born a few weeks early, but are in good health and both Mom and Dad are overjoyed."

The sex and names of the tots had not been released as WENN went to press.

The kids are the couple's first together, although British actor Moyer also has a 10-year-old daughter, Lilac, and 12-year-old son Billy from previous relationships.
