Chief Keef is headed back to jail.
The 18-year old rapper reportedly failed a drug test and a judge sent him back to jail.
Keef, a Chicago native, tweeted the breaking news this afternoon. Earlier in the year, he was arrested for driving 110 miles per hour in a 55-mph speeding zone. He was sentenced to 18-months probation at the time, but a condition of the order was random drug tests.
The jail stint will include rehab as well. Last month, Keef tested positive for weed and was promptly sent to jail. He only served 9-days of a 20-day sentence in jail.
The duration of his present incarceration was not immediately known.
