The seventh and final season of "Sons of Anarchy" may be packed with new plot twists as Marilyn Manson and Annabeth Gish were reportedly joining the rest of the cast.

Rocker Marilyn Manson was confirmed to be onboard on the FX's hit series. He said that he approached the series creator Kurt Sutter to be part of the show.

The rockstar said in his statement from FX's official press release, "Sons has been such a big part of my life, as well as my father's. 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 will play the role of the white supremacist named Ron Tully who is in prison. But, according to reports, Jax Teller will use him to expand his power base.

Meanwhile, Sutter is equally excited to have Marilyn Manson to join the show and immediately took to Twitter to share the good news.

Sutter is said to be thrilled with Manson's entry to the show. Post Manson's statement, he immediately took to Twitter to welcome him.

Meanwhile, X-Files actress Annabeth Gish will also be joining the season 7 of "Sons of Anarchy". Reports said that Gish will play the role of Althea Jarry, who is the new sheriff of Charming.

Previous reports also claimed that the cast will welcome a new sheriff to replace Eli Roosevelt who died last season. The female officer will be named Alice Johnson. Showrunner Sutter also confirmed that David Labrava, Niko Nicotera and Drea DeMatteo will be back for season 7 as series regulars joining Charlie Hunnam, Katey Sagal, Mark Boone Junior, Tommy Flanagan and Kim Coates.

"Sons of Anarchy" season 7 will be back on air in September.
