Scooplets on 'Psych,' 'Supernatural,' 'Melrose Place,' and more!

• Melrose Place: Singer-actress-bombshell Taryn Manning (Sons of Anarchy) will appear in the debut season’s third episode as a singer whose music video is being directed by Jonah. The week before, model-turned-actress Taylor Cole (Summerland) guests as David’s ex-girlfriend.

• Supernatural: The CW serial thriller is adding the recurring role of Raphael, a mechanic who becomes possessed by one of the most powerful beings in the universe. Speaking of powerful beings, I miss Keri Russell.

Wait, there’s more casting scoop after the jump!

• Psych: An American Werewolf in London‘s David Naughton has signed on to guest star in the show’s Halloween-themed episode, co-written by leading man James Roday. He’ll play Dr. Ken Tucker (no connection to EW TV critic extraordinaire), a self-serving sociopath with a plan that Shawn and Gus uncover. Psych‘s fourth season begins Aug. 7.

• Stargate: Universe: Producers are searching for a “name” actress to play the late wife of Robert Carlyle’s Nic Rush. The character will appear via flashback. SGU debuts this fall. Watch a clip here. Or don’t. No sweat off my back.
