'True Blood's' Kristin Van Straten (Vampire Pam) is Maleficent for 'Once Upon a Time'

Two of our fandoms are colliding and we could not be happier. Kristin Bauer (Van Straten), the snarky lesbian vampire Pam on "True Blood" is coming to "Once Upon a Time," a new ABC show that we named one of our most anticipated new shows for this fall.

Bauer tweets, "packing for Vancouver - to shoot #OnceUponaTime - new fantastical TV show."

Bauer will be guest-starring in one episode as Maleficent, the evil witch from "Sleeping Beauty" (so that's a third fandom colliding here), with the possibility for a recurring role,reports NiceGirlsTV. We think Bauer will make an amazing Maleficent.

"Once Upon a Time" spins the saga of fairy tale characters living in our world, in the small town of Storybrooke, Maine. We don't want to give too much else away, but it was a terrific pilot - something the whole family can enjoy.

"Once Upon a Time" premieres Sunday, Oct. 23 at 8 p.m. ET/PT on ABC.
