Dating a co-star may not have worked out for Ian Somerhalder, but how about dating someone who's on his show's sister series? Claire Holt stars on "The Vampire Diaries" spin-off "The Originals," making her close enough for comfort without them working directly together. Bonus! Ian's "Vampire Diaries" co-star Paul Wesley is currently seeing Claire's "Originals" co-star Phoebe Tonkin. Can you say double date?
