Keith Cozart, 18, walked out of the jail about 9 a.m., according to Cook County sheriff's office spokeswoman Sophia Ansari.
He had been in jail since Oct. 15, when he was ordered to jail for 20 days after testing positive for marijuana. Cozart received one day's credit from the sentencing judge, while receiving another 10 days credit for good behavior. That means he was behind bars 9 of the 20 days of his sentence.
An hour after he was released, Cozart, known for his Twitter and Instagram feeds, posted a snapshot picture of a text which read "I'm back b----."
Cozart was required to undergo random drug testing following a May 27 arrest in Northfield for driving 110 mph in his black 2011 BMW on the Edens Expy.
He pleaded guilty to the charge and paid a $531 fine. He also was ordered to serve 18 months probation and complete 60 hours of community service, in addition to the random drug tests.
Cozart has previously served time in juvenile detention for pointing a gun at Chicago Police officers. He was sent back to juvenile detention earlier this year for a violation of his parole for handling a firearm in a promotional video. This was Cozart's first stint in the jail, because he turned 18 in August.
Cozart missed an Oct. 21 court date in a child support case he's involved with while in the jail, but his lawyer appeared on his behalf, Ansari said. He's scheduled for a court hearing at the Daley Center court complex in downtown Chicago on Dec. 10. The case is one of two child-support cases against Cozart.
Jasmine Woodford, the plaintiff, has accused Keef of contempt for failing to pay the full amount of child support ordered in the case. On Oct. 21, Cook County Judge Mary Trew ordered Cozart to turn over child support funds to Woodford, Ansari said.
According to the child-support suit, Cozart signed a document acknowledging he is the father of a girl born in November 2011 to Woodford.
In June, Cozart was hit with a second paternity suit. The plaintiff, 29-year-old Erica Early, claims Keef fathered her daughter, born on Jan. 28.
Cozart, who grew up in Englewood, currently lives in Northbrook. He gained notoriety last year for a gloating tweet sent from his account after the slaying of a rival rapper.
