Chief Keef Released from Jail for Good Behavior and Negative Drug Test 11 Days Earlier, Tweets 'I'm Back B**ch.'

Chicago Sun-Times are reporting that rapper Chief Keef was released from prison after being jailed for nine days for failing a required drug test. The rapper celebrated his freedom tweeting a picture that captioned, "I'm back b----."

The Cook County Jail let the 18-year-old rapper go Thursday morning, according to Cook County sheriff's office spokeswoman Sophia Ansari.

Keef was released 11 days early after passing a drug test for marijuana. The judge granted the rapper 1 day for testing positive, in addition for 10 days of good behavior.

In 2011, Keef was arrested for speeding and was required to take random drug tests after he plead guilty. The "I Don't Like" rapper paid a $531 fine and was ordered to serve 18 months of probation and finish 60 hours of community service.

In August, the rapper had other legal woes, and was slapped with a pending lawsuit, which costs him $230,019. Team Major promoters sued the rapper $230,019 for missing his December 2012 performance in U.K.

The promoters claimed that the missed event cost them $75,000, which included his advance. The 17-year-old rapper's team never responded to the lawsuit and the judge awarded Team Major $230,019 for damages, loss of earnings, and reputational harm.
