As fans await the new season of Sons of Anarchy, creator Kurt Sutter has revealed that rocker Marilyn Manson may be guest-starring in the upcoming season premiere.

"Listening to one of @marilynmanson new songs. potent. creepy. cool. look for him in season 7. he'll be the guy riding the dragon," Sutter tweeted to his fans.

Sutter has revealed that season 7 will be the series' last, despite its soaring popularity.

Fans are curious as to how the final season will play out, but not even Sutter's wife Katey Sagal, who plays Gemma, knows what will happen. Gemma shockingly murdered Jax's wife in season 6 and viewers will have to find out what he does when he finds out that his own mother killed his wife. As of now, Gemma's fate is unknown.

On April 15, a photo of Jax was posted by the official Sons of Anarchy Facebook page with the caption: "...I have tremendous remorse for the acts of violence I've committed, both planned and spontaneous. But I think what brings me the most sorrow is that I've learned to justify this behavior. I always find a reason, a cause, a need that allows me the karmic lubrication to stuff the guilt into a savage compartment. I've become the thing, the one I hated..."

Niko Nicotera, David Labrava and Drea de Matteo have been promoted to regulars for the upcoming series, and Robert Brown, Marcus Alvarez and August Marks will also be returning.

Sons of Anarchy season 7 is set to return to AMC in fall 2014.
