Gerard Butler Successfully Completes Rehab Treatment For Substance Abuse: UPDATE

UPDATE: Gerard Butler finished his rehab treatment on Friday morning. A rep for the actor tells Gossip Cop, "Gerard has completed a successful course of treatment and has returned home in good health."

PREVIOUSLY: After battling prescription drug abuse, Gerard Butler has reportedly checked into the Betty Ford Center for rehab.

According to TMZ, the 42-year-old's aggressive role in the 2006 film "300" led him to take prescription drugs as a form of pain management. The Scottish actor's substance use only increased while filming "Of Men and Mavericks," during which he was injured in an on-set surfing accident.

"In the movie, I put in a scene about a 'two wave hold down,' when you are down for so long that the next wave comes over before you get back up, and that's what happened to me," Butler later said of his dangerous surfer role. "They finally grabbed me just as another huge wave was coming in. It was just like a movie! In fact, everything I talked about happening in the movie happened to me."

TMZ is also reporting that Butler is not only battling a prescription drug addiction but has "developed issues with cocaine."

Butler reportedly first checked into the Betty Ford Center three weeks ago to seek professional help for his addictions and may be leaving the clinic as soon as today.
