Though he has only spent four days in jail, it has already become clear that rapper Lil Wayne doesn't fit in with the general population.

The incarcerated MC has already been forced to remove his $100,000 diamond and gold grill from his mouth and undergo eight root canals in order to avoid problems, and now he's being warned not to sign autographs for his fellow inmates.

According to reports, officials at New York City's Rikers island, where Wayne is currently serving a one-year sentence for a weapons violation, have enacted a strict no-autograph policy for the length of the rapper's stay.

"Lil Wayne is not a celebrity in here," said a representative for the correction officers.

The multi-platinum-selling MC began serving his sentence on Monday, March 8, but might see release in as little as eight months time, if he receives good behavior.
