Anna Paquin Stephen Moyer Gold's Gym workout holding hands X-Men True Blood Vampires hbo

It's happened many times before in TV history - on-screen romance heats up off-screen! (Remember Seth and Summer? Sadness.) Such is the case with True Blood co-stars Anna Paquin and Stephen Moyer. Check out the adorbs couple post-workout on Sunday. They look so happy and healthy together!

Let's hope this romance lasts... for the sake of the show!
