The 37-year-old Jennings pleaded guilty on Wednesday to driving under the influence, fleeing and attempting to elude police, possession of a firearm by a convicted felon and discharging a weapon near a street.
Jennings was arrested in Smyrna on Oct. 19, 2008. Police say Jennings had a dispute with the mother of his children, Joy Bounds, and fired shots into the house where he thought she was staying before fleeing from police.
The R&B singer’s most recent album, I Still Believe, was released this year.
Jennings served 10 years in prison after being convicted of arson in Ohio in 1992.
