Stephen Moyer thinks having twins with Anna Paquin is going to be crazy.
The True Blood actor – who is married to his co-star – already has two children, Billy and Lilac, from previous relationships and the 42-year-old star anticipates that fathering duties are about to get dramatically more hectic.
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!"
Moyer's 29-year-old wife has continued to record their vampire television series despite her pregnancy and Michael McMillian, who plays Steve Newlin on the show, believes bosses are taking good care of Anna.
He told website UsMagazine.com: "The show is taking great care of her, and I think she's probably really happy that she has some time off now to focus on what's to come."
Michael (33) added: "Stephen is already a terrific father and they make an amazing couple. Anna is really excited, as any expectant mum is. I think they're going to be pretty cool parents."
The couple got married on 21 August 2010 and their hit series was recently renewed for a sixth season by HBO.
