LOS ANGELES (Reuters) - Actor David Duchovny, who plays a womanizing novelist on the cable television series "Californication," has completed a rehabilitation program for sex addiction, his attorney said on Monday.

Duchovny, former star of the "X-Files" films and TV series, is married to actress Tea Leoni and they have two children.

The actor's admission to a rehab facility for treatment of sex addiction was publicly revealed by his attorney, Stanton "Larry" Stein, in late August.

In a statement on Monday, Stanton said Duchovny "has successfully completed rehabilitation."

"He is out and will very soon begin work on his new movie," Stanton said.

Stein declined to say where the actor had been treated or when he left the center.

In January, Duchovny won a Golden Globe Award as best actor in a comedy for his role as Hank Moody, an oversexed single dad and novelist struggling with writer's block in the Showtime series "Californication."

Duchovny, 48, is set to star in a film called "The Joneses" scheduled for release next year.
