'The Vampire Diaries' newest vamp: 'Supernatural's' Lauren Cohan to play Rose

spn-tvd-lauren-cohan-320.jpgThere's a new vampire in Mystic Falls, "Vampire Diaries" fans. Sources confirm to Zap2it that "Supernatural's" Lauren Cohan will be sinking her teeth into the role of Rose, a tough, sexy vampire who might just catch Damon's ( Ian Somerhalder) eye.

But then again, doesn't everybody?

Rose is over 500 years old and described as disarmingly elegant despite a "tough girl" first impression. Five centuries of bloodsucking have given her a certain edge. "Maybe there's some humanity left in her -- have fun finding it," my source says.

She's expected to make her first appearance in Episode 8, titled "Rose" -- yeah, she's kind of a big deal.

Cohan is best known for her role as the mercenary Bela Talbot on "Supernatural." She had a coy love-hate flirtation with Dean ( Jensen Ackles) and appeared in Sam's ( Jared Padalecki) dirty dreams. If she can get those two all hot and bothered, I think she'll fit in just fine with the Mystic Falls gang.

What do you all think? Could she be hot enough for a Damon hookup? How dangerous do 500 years of undeath make a woman? And what's she doing in Mystic Falls? Let's hear it in the comments below.
