Fat Joe has just turned himself in to prison, reports indicate.
The rapper will serve a four-month sentence for tax evasion.
He is in custody at the Federal Detention Center in Miami.
Fat Joe pleaded guilty back in December to not paying federal income taxes for the fiscal years 2007 and 2008, owing the U.S. more than $1 million.
Yes, Joe's income is high enough that he owes that much in taxes, and yes, Joe declined to pay the bills a la Wesley Snipes, Lauryn Hill, etc.
He originally faced up two years in prison, but ultimately was sentenced to just four months and a $15,000 fine, plus a year of supervised release.
