Chief Keef is dealing with additional legal trouble while behind bars. The 17-year old rapper is being sued for child support by a girl who is still in middle school.
According to TMZ, Keef got the girl pregnant in 2011 when he was 15.
In the state of Illinois it is considered a misdemeanor for two people under the age of 17 to have sex, even if it's consensual. If both parties are between 9 and 17 years old, the older person commits a crime called "criminal sexual abuse."
TMZ reports that if prosecuted and convicted, Keef could serve up to one year in jail and have to register as a sex offender for 10 years. However, that hardly ever happens in cases like these.
The unidentified girl, whose current age is unknown, is suing Keef, real name Keith Cozart, for child support, health insurance and other medical expenses.
Keef is currently serving a 60-day juvenile detention sentence in Chicago for violating his probation on a previous gun charge.
