Having previously spoken about their chemistry in the first movie instalment of the vampire saga, she also reckons “they're awesome together” in real-life too.

“Well, I think they're both fascinating, tortured, artists,” she tells E!Online hen asked what makes them work as a couple.

“Which is kind of cool to be with somebody else that gets what that's like. They are both amazing with very interesting minds. So that's kind of cool, too.”
