Season five of Lost Girl is set to premiere on Showcase. And yes, it’s the final season of the critically-acclaimed supernatural drama. That’s the bad news. The good news? Expect Lost Girl to go out with a bang, courtesy of several high-profile guest stars.

Here’s who’s been confirmed so far: Eric Roberts (The Dark Knight, The Expendables), Luke Bilyk (My Babysitter’s a Vampire, Degrassi: The Next Generation), Noam Jenkins (Covert Affairs, Rookie Blue, Longmire), Amanda Walsh (Two and a Half Men, NCIS, Grimm) and Shanice Banton (Degrassi: The Next Generation, A Day Late and a Dollar Short).

Lost Girl follows supernatural seductress Bo (Anna Silk), the loveable succubus who feeds off sexual energy. Since realizing she is part of the Fae — creatures of legend and folklore who live among humans — Bo has forged her own path between the human and Fae worlds, while embarking on a mission to unlock the secrets of her origin.

Lost Girl season 5, part 1 premieres December 7 at 9pm ET/PT.
