Country superstar Alan Jackson's 20-year-old daughter Alexandra is in a whole lot of trouble. Not only did she get drunk when she's not yet legally old enough to do that, she sassed a cop and then hit him in the chest. Bad moves, all.

According to a police affidavit, Alexandra "Ali" Jackson was the passenger in a Range Rover that was pulled over in Nashville early Wednesday morning for speeding and tailgating. While an officer was questioning the driver, Ali staggered out of the car, became belligerent and began "making demands."

One report says she told the cops that her father “would do anything [she] wanted him to do," but backed down when the officer warned her that bribery is, you know, kind of illegal.

She wasn't done yet, though. After Ali "raised her hand toward police in a threatening manner," the cops told her to get back in the vehicle. She refused, and then she then hit an officer in the chest for good measure. Which, as you probably know, is an express ticket to jail.

Ali was eventually charged with assault, consumption of alcohol under the age of 21 and resisting arrest. After being released on a $35,000 bond, she was scheduled for a Sept. 23 court date.

This is the second time in the past year that one of Alan's kids has been arrested on an alcohol-related offense. Last August, 22-year-old Mattie Jackson was pinched for DUI and later convicted on a misdemeanor charge of reckless driving.
