Paquin is just glad they have enough chemistry to make them believable.
"Chemistry is just one of those elusive things. It doesn't mean everyone's gonna jump in bed with everyone," she told Look magazine.
"It's not even specifically about sexual chemistry. It's just, is there a spark when you work with that person? Does it feel like there's a connection? Does it feel like they're really coming alive? It has always been really, really easy to work with him."
Paquin also says she likes exercise which makes her feel like she wants to die.
She has to wear a variety of barely-there outfits for her True Blood role, so makes sure she's always in shape.
Paquin exercises hard and wants people to know her svelte figure doesn't come easily.
"Everything!" she replied when asked what she does to stay in shape.
"I like it if it's really gruelling and in the middle I feel like I really want to die! I like a challenge. One of the things I like to do is box it's possibly better than therapy. A lot of times for women there's not an opportunity to have a physical outlet for our feelings, because we're taught not to be aggressive."
Paquin gets annoyed when she reads other celebrities saying they don't exercise and eat whatever they like. She doesn't think it's honest or fair on fans.
"I work out like a maniac and I spray tan a lot. Genetics were kind, but I work very hard," she told the magazine.
