Showtime is ending their signature series "Californication" and is wrapping up its final season with 12 episodes in April 2014. The dark comedy stars "The X-Files" actor David Duchovny as a troubled novelist who moves to California as he struggles from a writer's block.

The show's creator Tom Kapinos will "neatly wrap up" the lives of the characters on the show including Hank Moody's rock star life, his long-time lover Karen (Natascha McElhone), daughter Becca (Madeleine Martin), manager Charlie (Evan Handler) and pal Marcy (Pamela Adlon).

"With its unique blend of lyricism and excess, Californication has been one of our groundbreaking signature series," says Showtime's president of entertainment David Nevins. "We will always be indebted to Tom Kapinos for leading the creative charge on this memorable comedy, and to David Duchovny for making us root for an unapologetic hedonist like Hank Moody," he added.

"Californication" is Showtime's longest-running series and has won numerous awards, including two Emmys and Golden Globe for Dochovny. According to The Hollywood Reporter, the show's season 6 marks the highest rated season as the show gained 2.9 million viewers across various platforms. This final season will feature guest stars Heather Graham and Mary Lynn Rajskub. Graham will play as Hank's old friend Julia, a mystery woman who will threaten Hank's life with Karen.

"One Life To Live" star Roger Howarth is also set to make an appearance for a multi-episode arc, including Oliver Cooper from "Project X" as he plays Levon, a budding writer who is trying to emulate Hank. "Californication's" regular guest Rob Lowe will reprise his role as Eddie Nero.

Season 7 features 12 30-minute episodes that will follow Hank as he joins the writer's room thanks to his never-released film, "Santa Monica Cop." The arrival of Julia, Hank's old friend, will stir up some drama between Hank and Karen.

The 52-year-old-actor is currently working with director Larry Moss' "Relative Insanity," an adaptation of Anton Chekhov's "The Seagull" set in the present-day New York City and the Hamptons. Duchovny also starred in Anthony Fabian's "Louder Than Words" which premiered at the Hamptons International Film Festival.
