As his former friend, Steve Coogan, defends himself against accusations of over-partying, Owen Wilson has returned home.

The troubled actor will be watched around the clock.

"Owen is in bad mental shape but said he is thankful to be alive," says a source close to the actor, who had returned to his Santa Monica home on Saturday. "He knows he came close to ending his life, and he is happy that he was saved from himself. He is basically at home with people watching him 24/7."

Wilson's rep declined to comment to People magazine.

The actor was hospitalized August 26 after what a police log called an attempt suicide. He spent the next several days at Los Angeles' Cedars-Sinai Medical Center with constant visits from brothers Andrew and Luke Wilson, his parents and such friends as Wes Anderson and Woody Harrelson.
