The two are equally as perfect for each other off screen as they are on, with Moyer recently telling E!, "There's no one I'd rather work with. I love working with her and that's how it all started, by falling in love on camera."
Anna recently admitted their real-life romance makes it easy for them to shoot nude scenes. She said: “I feel fine. Although the way that people ask me about it all the time, I feel like maybe I should feel uptight about it. But I really don't.
"Obviously, if you're already with that person then you're not having to sort of get over the, 'Wow, I'm naked with someone that I don't even know the middle name of!’
"I think that regardless of what kind of scene you're doing, the better you know the person... the more open and real your performance can be. And that goes for stunt scenes and heavy emotional scenes and sex scenes. OK, so I have a little bit of a leg up in that particular area with my on-screen partner."
The two have been a couple since February. Stephen, 39, has two children, son Billy, nine, and seven-year-old daughter Lilac from previous relationships. Guess vampires move fast! Congrats to the happy couple!
