The entertainment website claims that Williams is being held in the prison ward of Bellevue Hospital Center in New York.
Williams has a history of trouble, including the shooting death of his limo driver in 2002. Williams was convicted of covering up the shooting and recently reportedly agreed to a deal that would send him to prison for up to three years.
Williams was also hospitalized last year after holing up in hotel and trashing his room. Hotel officials called police after deeming Williams "suicidal."
