Ready or not ... Lauryn Hill has just reported to federal prison in Connecticut, where she will begin her 3 month sentence for tax evasion, TMZ has learned.
Officials tell TMZ ... the former Fugees singer was booked into the Federal Correctional Institution in Danbury at 11:15 AM EST.
We're told the FCI is a "minimum security type facility" where inmates live in "barracks type" housing.
We're also told 38-year-old Hill will not be isolated in the facility -- and will be housed with the general population.
As we previously reported, Hill pled guilty last year to three counts of tax evasion for failing to file returns on $1.8 million she earned from 2005 to 2007.
