Imprisoned rapper Lil' Kim and other inmates at Philadelphia's Federal Detention Center recently ran afoul of the rules governing cell phones.

The rap star and some of her fellow female inmates lost their visitor privileges after a visitor tried to smuggle a cell phone into the prison, sources told the Philadelphia News.

Nearly half the female population at the prison have been without visitors for about two weeks, the sources said.

The source also said Kim, who began serving a one year and one day sentence for perjury in September, was rumored to be the intended source of the contraband.

"It has nothing to do with Kim," her attorney, James J. Leonard Jr., told the newspaper, adding she has been a "model inmate" and is expected to be released in July.

A spokeswoman for the federal prison said she would not comment on "any internal security procedures or any specific incidents within the facility."
