After his arrest in May, Gunna is trying to secure his release from jail through a last-ditch petition effort.
Gunna, whose real name is Sergio Kitchens, turned himself in to the Fulton County Sheriff's.
For several months, Gunna's attorneys have been asking a Fulton County judge to free Gunna on bond, to no avail.
On Wednesday, Kardashian took to Twitter to back the rapper's efforts with a simple but effective message.
If Gunna's petition fails, Gunna may have to remain behind bars in Georgia until January, when his case is scheduled to go to trial.
Gunna's attorneys Donald F. Samuel, John A. Garland and Kristen W. Novay released a statement following the rapper's arrest.
"Mr. Sergio Kitchens, known as Gunna, is innocent. The indictment falsely portrays his music as part of criminal conspiracy," his attorney's said in their statement.
