The 48-year-old actor checked himself into the Meadows rehab centre in Wickenburg, Arizona in August (08) in a bid to control his sexual urges.

But the star left the centre on Monday (06Oct08) to begin work on a new movie.

His lawyer Larry Stein tells People.com, "David is out of rehab and about to start a new movie. He successfully completed his treatment."
