Marilyn Manson has joined the cast of Sons of Anarchy for the final season.

The 45-year-old rocker will play "a white supremacist prison shot-caller" named Ron Tully, who is set to help the show's protagonist Jackson "Jax" Teller (Charlie Hunnam) "expand his power base" in the program, which portrays police and motorcycle gangs in California.

Manson and his dad, Hugh Warner, have always been huge fans of the show which was created by Kurt Sutter, and the shock rocker admitted he is joining the series to make his father proud: "Sons has been such a big part of my life, as well as my father's. The very heart of SOA is about [the father-son] relationship ... So I was determined to make him proud by being involved in what will probably be remembered as the most amazing piece of television cinema. After all, the very heart of SOA is about that relationship. So, now all I need is a motorcycle."

Manson - whose real name is Brian Hugh Warner - has previously appeared in shows including Californication, Once Upon a Time and Eastbound & Down.
