Los Angeles prosecutors are charging the father of singers Jessica and Ashley Simpson with two counts of drunken driving after his arrest earlier this month.
City attorney's spokesman Frank Mateljan said on Wednesday that 54-year-old Joe Simpson faces a maximum sentence of six months in jail, 36 months of probation and a $US1000 ($A955) fine.
He was arrested on August 4 after authorities say he registered a blood-alcohol level of 0.08 per cent or above at a DUI checkpoint in the Sherman Oaks area.
The charges were filed on Tuesday. Simpson is due for arraignment on August 30 in a Van Nuys court.
Simpson is a former minister. He helped make stars of his two daughters by managing their singing careers.
