Uh oh! Here's something that Chief Keef might not like. The Chicago rapper is being sued by his landlord for owing back rent.

According to TMZ, Georghe Simoniak-Sas recently filed a lawsuit against Keef and his uncle claiming that he owes $4,700 for the months of July and August on the Illinois mansion they are renting.

The landlord is so fed up with the drill rapper that he's seeking to have him evicted from the property and collect the $9,400 in back rent.

Keef, who just turned 18, has been slapped with a few lawsuits in the past weeks. Recently, the 'Sosa' rapper was ordered to pay a concert promoter $230,000 for not showing up to a scheduled gig. Additionally, he has a couple of baby mamas suing him for child support.

We hope that Chief Keef can resolve his legal issues. It's time for him to grow up and start acting like a responsible human being. These lawsuits are only going to slow down his struggle rap career.
