Rapper Lil Wayne will be going solo for the remainder of his prison sentence.
Correction Department spokesman Stephen Morello said Lil Wayne was moved into what New York City jail officials call “punitive segregation”.
It is his punishment for stashing a charger and headphones for a digital music player in a potato crisps bag in his cell.
The Grammy Award-winning rapper previously was allowed to spend most of the day mingling with other inmates at the Rikers Island jail complex.
Now, he will usually be confined to his new cell 23 hours a day and kept apart from other inmates during recreation time.
The rapper, born Dwayne Carter, has been in jail since March and is expected to be released on November 4.
He pleaded guilty to attempted criminal possession of a weapon.
