Phoebe Tonkin Cast on The Vampire Diaries!!!

We can't even pretend to hide our enthusiasm over this bit of Vampire Diaries casting news, especially because TV Fanatic would like to think we had something to do with it:

Former Secret Circle actress Phoebe Tonkin will come on board Season 4 of The CW smash as Hayley, premiering on Episode 3 this fall and portraying a sexy, free-spirited blast from Tyler's past.

As previously reported, the character is likely to cause problems for Tyler and Caroline.

At Comic-Con last month, I asked Kevin Williamson about the possibility of casting Tonkin and then followed up by pleading with Julie Plec.

The latter assured me that if they found a role for the Australian beauty, it would be a long-lasting gig, meaning Vampire Diaries fans can expect to see plenty of Tonkin on our screens in 2012-2013.

If you'll now excuse us, we must go celebrate... and figure out how we'll ever choose between Phoebe and Candice Accola. Good luck with that one, Tyler. We both envy you and feel for you.
