Look Who Will Be Vamping it Up on 'Supernatural' This Season

The premiere of the third season of Supernatural is less than a week awhile. While I can't wait for the return of the Winchester boys, I am equally excited about this season's guest stars. At the top of the list is an Angel/Buffy alumnus Mercedes McNabb. *** The following might contain some spoilers***

McNabb played the role of former party girl-turned vampire Harmony and the BFF of Cordelia (Charisma Chase) on Buffy the Vampire and later reprised her role on the spin-off Angel. The blonde Harmony proved that just because you were a vampire doesn't mean you don't have blonde moments.

An apparently her new guest spot on Supernatural won't be a big stretch for her as she's once again plays a girl whose penchant for partying leaves her as a bloodsucker.

McNabb will turn up on the sixth episode of Supernatural scheduled to appear November 15 in a episode involving rogue vampire hunter Gordon Dean played by Sterling K. Brown of Army Wives and a vamp set on revenge.

No word yet on whether the two new additions -- hunter Ruby (Katie Cassidy) and mercenary Bela (Lauren Cohan) -- will be around to help with the vamp problem.

We already know that fellow hunter Bobby (Jim Beaver) and Ellen (Samantha Ferris) will be returning to help Dean (Jensen Ackles) and Sam (Jared Padelecki) Winchester and that FBI Agent Henrickson (Charles Malik Whitfield) will still be pursuing the boys, but let's see who else's path the boys will cross in Season 3.

In the premiere, the boys will not only meet Ruby, but also another pair of hunters to battle seven demons representing the seven deadly sins. But this pair is married and they don't want anything to do with Dean and Sam. Apparently, the hunter community isn't too happy with the boys for opening the gates of hell. Caroline Chikezie (Elaine Hardy on Footballers' Wives) will portray Tamara while the role of her husband Isaac is filled by Emmy-winner Peter Macon.
