"The reason it was dodged last year was very intentional on both our parts," Moyer, 39, said at the time. "It was very important to me that the cast and crew we were working with didn't feel it was fickle, and didn't feel it could possibly potentially encroach on their lives, you know, just like, 'Oh the two stars are having a thing.' We didn't want to take anything away from the show."

Moyer -- who has two young children from a previous relationship -- divides his time between the home he shares with Paquin, 27, in L.A. and his native London.

Will Anna and Stephen last as long as these famously happy couples?

"It's just exciting, and that was there from day one," Moyer has said. "We always take the p--- out of each other and are silly with each other, and it is great. We're very, very happy. She's the best."
