TMZ has learned that Jessica and Ashlee Simpson's dad was arrested last weekend for DUI. LAPD officers pulled over Joe Simpson's car Saturday night around 10p on Ventura Blvd. in Sherman Oaks, CA and was eventually arrested.

During the stop, the officers on-scene felt that Joe was intoxicated and he was eventually asked to get out of the car and that's when he was arrested and taken to jail.

Joe ended up spending the night in jail and was released Sunday morning without having to post bail. He's not likely to face criminal charges in this case because it was his first offense but could be facing a huge fine once the case is reviewed by the L.A. City Attorney.
