As reported by ABC News, Chevy Chase has recently checked into rehab for “an alcohol-related issue.” He’ll be at the Hazelden Addiction Treatment Center in Minnesota for what a rep is calling a “tune-up,” with a TMZ report adding that Chase “wants to be the best that he can be.” Chase previously underwent a rehab stint back in the ‘80s, checking into the famous Betty Ford Clinic to recover from a painkiller addiction.
