Is TVD's Joseph Morgan Dating Claire Hot?

We were so sad to learn Vampire Diaries'Joseph Morgan (Klaus) andRevenge'sEmily VanCamp (Emily Thorne) hadcalled it quits — they were a gorgeous couple! But she's rumored to havemoved on quicker than a judo-master Hamptonite to her co-starJoshua Bowman, and while it seems like the exes are still friends, that must be hard to watch. But eagle-eyed TVD fans have been asking us one question: Are Joseph Morgan and his on-screen sister, Claire Holt (Rebekah), an item?

The pair did seem to become fast pals on the Atlanta set. He even invited her (and his Original brother Daniel Gillies) to theImmortals premiere in November. And yes, shetweeted that adorable photo of the two of them together, but Joseph'sbeen known to takecute snaps withKat Graham as well. But he rarely tweets at Ms. Graham, while his Twitter timeline is full of replies to @MissClaireHolt.

We don't generally call anyone "monkey" except our dog, so it's a possible term of endearment. The last piece of evidence? Joseph has met andhung out with Claire's BFF, Secret Circle'sPhoebe Tonkin. You know what the Spice Girls would say about that…
So we're all for these two hot blondes with accents getting together. They can double date withNina Dobrev and Ian Somerhalder!
