The `True Blood` actress and her husband Stephen Moyer welcomed the pair of babies a few weeks early, but both are delighted - although neither the names nor the sex has been confirmed.
A representative said: "We can confirm AnnaPaquin and Stephen Moyer recently welcomed their twins into the world. The babies were born a few weeks early, but are in good health and mom and dad are overjoyed."
Stephen - who already has children Billy and Lilac from a previous relationship - recently said he having two more kids in addition to his own would be "crazy", but he was looking forward to it.
He said: "I love my kids beyond anything. They`re the best things ever, and having two more is just going to be even more crazy, but that`s cool!"
Anna claimed she was looking forward to settling down with the pair and being a "nesty" parent.
She said: "I have a side that`s very nesty. And another that thinks, `Let`s lock up the house and go away for five months.` "
