T.I. will begin serving a prison sentence on federal weapons charges by May 26.

The 28-year-old rapper, whose real name is Clifford J. Harris Jr., will be serving his sentence of one year and a day at the Forrest City low-security federal prison in Arkansas. Paperwork filed in his federal court case shows he has until noon on May 26 to report for his sentence.

Harris pleaded guilty to the charges after he tried to buy a stash of machine guns and silencers in Atlanta to protect himself after his best friend was killed. He will also pay a $100,000 fine as part of his sentence.

Prison officials didn't immediately return a call Friday for comment.
