After violating his probation, rapper Lil Pump will face prison time, forcing him to cancel his upcoming “Harverd Dropout Tour.”

The “Gucci Gang” singer, who is 18-years-old, was arrested in Miami this past August for driving without a license. According to police, the license plate on his Rolls-Royce belonged to a Mini Cooper. This isn’t the first time he’s faced charges; he was previously arrested for firing a gun in his California home and lying to police.

Lil Pump told fans that his Miami arrest violated his probation and he would have to “go in and do a couple months.”

“I got some crazy-ass shit dropping,” he said in a video posted to Twitter. “I’m gonna have something for you, don’t worry – it’s gonna be crazy…Listen up kids: Stay in school, don’t f*** up like me.”

“Due to unforeseen circumstances, Lil Pump’s ‘Harverd Dropout Tour’ has been canceled,” a representative for Lil Pump said in a statement. “Refunds will be provided at point of purchase. We apologize for any inconvenience.”

Lil Pump was supposed to head out on a 15-show tour to kick-off on September 28 in Denver, Colorado.

While the rapper’s sophomore record was due this September, the release was pushed back and the due date is unknown at this time. He recently collaborated with Kanye West on the track “I Love It,” which the two performed together on Saturday Night Live this past weekend.
