David Hasselhoff has checked himself into The Betty Ford Center for treatment of alcoholism.

The former Baywatch star, who turns 50 next week, issued a release Monday announcing the voluntary stay at the hospital.

``He realized his social drinking had increased more than he was comfortable with and he decided to do something about it,'' publicist Richard Hoffman said in a statement.

The actor checked in June 26; his representatives said they didn't know how long he would be there.

Hasselhoff's recent roles included a cameo appearance as himself in the summer comedy The New Guy and he performed on Broadway last year in the musical Jekyll & Hyde.
