Nina Dobrev Will 'Rock It Out' As Vampire Elena, Kat Graham Gushes

Nina Dobrev's been pulling double duty on "The Vampire Diaries" for a while now—portraying both human Elena Gilbert and her lookalike, vampire Katherine Pierce. But after Elena's transformation during the season three finale last week, it looks like the Canadian cutie will be all vampire, all the time (and we couldn't be more excited to see how this plays out). Of course, we're not the only ones. Nina's co-star Kat Graham is also pretty stoked by the idea.

"Oh well, I’m so excited," Kat shared with MTV News earlier this week at Wango Tango. "I love Nina. I’m a huge fan of her. She works so hard and, as her friend, I get to see when she plays Katherine versus when she plays Elena. So it’s really great for me to be able to, I don’t know, I’m getting so excited to see what she’s going to do because it obviously has to be different than Katherine. And she’s definitely going to bring the vulnerability of Elena to it, and she’s gonna rock it out. I know she will."

But it might not be just Elena who makes a move to the dark side. Kat shared that witchy Bonnie might also embrace that side of herself next season.

“Well, a lot of her decisions that she made in the episode ‘Before Sunset’ and the season finale were affected by, I think, the whole of season three and the things that happened and her making the statement that ‘I’m not gonna let you guys push me around anymore,'" she said. "So I think you’re gonna see an even stronger Bonnie, a more surprising Bonnie, a character that’s gonna make some decisions that are going to surprise people. And then I feel like a lot of people want to see a darker Bonnie. So we’ll see if they play with that. It’s amazing. I’m surprised. I thought that people wanted Bonnie to have a halo all the time. But if it’s justified than it’s never bad."
