Grammy-winning singer Lauryn Hill has begun serving her three-month prison sentence for failing to pay about $1m (£670,000) in taxes over the past decade.
Hill is serving her time at a federal prison in Danbury in the state of Connecticut, Ed Ross, a spokesman for the Federal Bureau of Prisons, said.
Inmates at the minimum-security prison live in open dormitory-style living quarters and are expected to do jobs such as maintenance, food service and landscaping.
Hill, who started singing with the Fugees as a teenager in the 1990s before releasing her multi-platinum 1998 album The Miseducation Of Lauryn Hill, pleaded guilty last year in New Jersey to failing to pay taxes on more than £1.2m earned from 2005 to 2007.
Her sentencing also took into account unpaid state and federal taxes in 2008 and 2009 that brought the total earnings to about £1.5m.
Her lawyer had requested probation, arguing that Hill's charitable works, her family circumstances and the fact she paid back the taxes she owed should be taken into account.
During her sentencing in May in Newark, New Jersey, Hill described how she failed to pay taxes during a period when she had dropped out of the music business to protect herself and her children - she has six in total.
She explained that the treatment she had received while she was in the entertainment business was the reason she decided to leave it.
Assistant US Attorney Sandra Moser acknowledged Hill's creative talent and work on behalf of impoverished children, but called Hill's explanation for her actions a "parade of excuses centring around her feeling put upon" that did not exempt her from her responsibilities.
After she is released from prison, she will be under parole supervision for a year, the first three months of which will be spent under house arrest.
