Actor Chris Klein has returned to work following a two-month rehab stint stemming from an alcohol-related arrest in June (10) - to film a cameo role on U.S. TV series THE GOOD GUYS.
The American Pie star was taken into custody and charged with two misdemeanours after failing a sobriety test when his car was pulled over by cops on an Los Angeles freeway.
Klein, who spent four days behind bars, pleaded no content to the DUI counts and was released on bail after agreeing to enrol in an alcohol education programme.
He checked himself into Utah's Cirque Lodge rehab facility for two months of treatment in a bid to kick his alcohol issues.
And now the 31 year old is shooting his guest spot on the police comedy, starring Colin Hanks and Bradley Whitford, reports People.com.
The star's run-in with the law in June (10) was his second DUI arrest in five years - he was busted on a similar charge in 2005.
