Anna Paquin & Stephen Moyer Are 'Swingers'

Anna Paquin and fiance Stephen Moyer spend their morning going on an ocean front bicycle ride before stopping off and working out on a swing set on Sunday (April 18) in Santa Monica, Calif.

“It’s HBO’s fault,” Stephen, 40, said of his getting together with his True Blood co-star. “They put us in the same hotel” – though in not the same room, at least “not to begin with,” he adds.

“No, I’m joking,” he told Details. “They put us in these hotel suites, and we hung out for a while and got to know each other. The attraction was there, so it was a matter of whether we acted on it or not.”
