As if the casting of Melinda Clarke as Matt's mom on The Vampire Diaries wasn't exciting enough...

Executive producer Kevin Williamson has confirmed that Clarke's Kelly Donovan will jump right into the sack with everyone's favorite, devious blood-sucker: Damon Salvatore.

“If I didn’t have Kelly and Damon hook up there would be no God,” Williamson joked about with Michael Ausiello. “What’s the point of doing TV if you’re not going to put those two characters together? That’s going to be a fun relationship to explore.”

He can say that again!

The producer adds the character won't arrive in Mystic Falls solely for hot vampire sex. She'll have quite the history with the town’s adult population.

“We’ll reveal that she was friends with Sheriff [Elizabeth] and Elena’s mother,” he said. “The three of them were really tight friends back in the day. Sheriff and Kelly, in particular, have ongoing issues to deal with.”

Clarke debuts on March 25. We can't wait.
