AceShowbiz - Incarcerated rapper Lil Wayne has pleaded with fans to stop sending him letters to read behind bars, just days after he was placed in isolation for possessing prison contraband. The "Lollipop" hitmaker was recently caught with banned music equipment in his cell at New York's Rikers Island detention center for the second time during his eight-month sentence on illegal weapons charges. He was last reprimanded for the same violation in May.

Wayne was moved to a separate cell and currently spends 23 hours a day in isolation, according to TMZ.com. His only out-of-cell time is restricted to visits, religious services and 60 minutes of recreational time. Meanwhile, his phone privileges have been reduced to just one personal call a week.

And the hip-hop star, who had previously encouraged fanmail from his devotees, has now asked for the outpouring of supportive letters to stop. In posts on his Facebook.com and Twitter.com pages, he writes, "I can no longer write my fans, as difficult as this may be to say please stop sending me mail, I luv u (sic) and will see you soon."

It is not clear whether the fanmail request is directly related to his prison punishment for the contraband. Wayne is expected to be released on November 5.
