Being on True Blood
is bitingly good, but for Anna Paquin also having her fiancé on set of the HBO vampire series is simply the best.
"What makes relationships so difficult with my job is all the traveling and being away from your significant other," she tells Britain's Elle
for its October issue. "Eventually it gets too hard to maintain."
But since the Oscar-winning
actress, 27, began dating her TV vampire costar Stephen Moyer in February, life has been a dream, as they get to hang out constantly.
"It’s great to have the freedom to enjoy your work and not feel like you're leaving your other life behind," the New Zealand-raised Paquin says. "It’s a pretty sweet setup."
, Paquin and Moyer, 39 spend most of their downtime in London, thanks to British-born Moyer’s Essex roots.
"I’m happy with my London-slash-Los Angeles lifestyle with my English boyfriend," she says.
So, aside from their close proximity on set, where they've kept their romance discreet
, what was it that drew them together?
"It’s not so much about the things you have in common, like the fact that half the television I watched growing up was British TV," explains Paquin, who was born in Canada. "It’s just the shared experience of being foreign in America, a place where you’re sort of expected not to feel foreign."
For now, the newly engaged couple are happy living the American dream, at their home in Southern California's Venice Beach, drinking orange juice at a café near the ocean. "I could write a guidebook to spray-tanning," she jokes. "I’m fully transforming into the Californian babe."
