"Sons Of Anarchy" creator and executive producer Kurt Sutter took to Twitter to apologize for the leaked spoilers of the Dec. 9 series finale of the seventh season of the FX biker drama series.

In a lengthy tweet, Sutter ended with, "There is no excuse for utter ineptitude. It pains me that this will be the parting memory of some fans."

The spoilers of the "Sons of Anarchy Season 7" finale were leaked through the early shipping of the book "Sons of Anarchy: The Official Collector's Edition," according to People.

A spokesperson for the book's publisher Time Home Entertainment told Variety that they have "a very strict embargo in place for the on-sale date of Wednesday, December 10, 2014" and emphasized how proud they are of the book despite their extreme disappointment with the spoilers.

Sutter took the blame for the spoilers since the book was originally his idea but asked the fans not to share their "wrath or pain or opinion in social media so as to not spoil the experience of others."

In addition, Sutter asked the fans to tune in for the season finale and guaranteed that "it plays much better than it reads."

During the penultimate episode of "Sons of Anarchy Season 7" titled "Red Rose," Charlie Hunnam had a sex scene with Drea de Matteo and it could be his last one in the seventh season of the series, according to Just Jared.

In "Red Rose," Hunnam's character Jackson "Jax" Teller dealt with the decision of the fate of his mother played by Katey Seagal while the club was in danger.

"Sons Of Anarchy Season 7" also stars Kim Coates, Mark Boone Junior, Tommy Flanagan, Theo Rossi, Dayton Callie, David Labrava, Michael Ornstein, Winter Ave Zoli, Jimmy Smits, Niko Nicotera, Emilio Rivera, Ryder Londo and Rusty Coones, among others.

Meanwhile, Hunnam is set to appear in upcoming films "The Mountain Between Us," "Crimson Peak"  and "Knights of the Roundtable: King Arthur."
