Chevy Chase has checked into rehab.
Chevy Chase
The 'National Lampoon's Vacation' actor is an in-patient at the Hazelden Addiction Treatment Center in Minnesota - where Robin Williams was treated in 2014 - for an alcohol-related problem.
Chevy's rep told gossip website TMZ the star has entered the rehabilitation centre for a "tune up" and "wants to be the best that he can be".
This comes after the 72-year-old actor checked into the Betty Ford drug rehab centre in 1986 for a painkiller addiction.
His publicist said at the time that he'd developed a "dependency on prescription drugs relating to chronic and long-term back problems".
The issue occurred when he was a cast member on 'Saturday Night Live'.
The father-of-three is due to appear in movies 'The Christmas Apprentice' and 'Dog Years', both of which have wrapped production.
Between 2007 and 2009 he starred in two episodes of 'Family Guy', one as himself and another as Clark Griswold.
He has also appeared in 'Law & Order' and numerous episodes of 'SNL', which he hosted for eight episodes from 1978 to 1997.
Chevy has three daughters, Cydney, 33, Caley, 31, and Emily, 27, and lives with his third wife, Jayni, who he married in 1982.
He was previously married to Suzanne from 1973 to 1976 and Jacqueline from 1976 to 1980.
Robin - who struggled with substance abuse since the 1980s - checked into Hazelden in July 2014 for continued sobriety.
His rep said at the time: "After working back-to-back projects, Robin is simply taking the opportunity to fine-tune and focus on his continued commitment, of which he remains extremely proud."
Sadly, he was found dead at his home in Tiburon, Marin County, just a month later on August 11, 2014, after he committed suicide.
