Julian McMahon will be returning to Charmed in the 150th episode.

He will reprise the role of Cole, the half-human/half-demon ex-husband of Phoebe (Alyssa Milano).

In the 150th episode "The Seven Year Witch", he meets Piper in a cosmic void between life and death. He said: "I guess my life has gotten a little busier since 'Charmed,' but I still feel like the same person. 'Charmed,' for me, was a very integral and valued time in my life, both personally and professionally. To me, it's like going home."

McMahon has just finished filming for the upcoming film "Fantastic Four," in which he plays Dr Doom.

The 150th episode is the 16th episode of season seven. In Australia, we have seen up to episode 4 of the season seven.
