Chevy Chase has checked into rehab.
The National Lampoon's Vacation star is an in-patient at Hazelden Addiction Treatment Center in Minnesota, a representative for the actor confirms to PEOPLE.
Chase checked himself in for an alcohol-related issue which his rep calls a "tune-up," adding that the actor "wants to be the best that he can be."
He previously received addiction treatment at the Betty Ford Center in Rancho Mirage, California in the '80s, according to The New York Times.
The 72-year-old's latest project, Dog Years, in which he stars alongside Burt Reynolds, is currently being filmed. Another upcoming project, The Christmas Apprentice, has already wrapped.
