NEWARK, NJ — Grammy-winning singer Lauryn Hill pleaded guilty in federal court in Newark, New Jersey, on Friday to three counts of failing to file federal income tax returns.

Hill, 37, a hip hop singer and rapper best known as a former member of the Fugees and for a Grammy-winning 1998 solo album, pleaded guilty to failing to file federal returns between 2005 and 2007, despite earning an income of more than $1.8 million primarily from film and recording royalties.

Each count carries a maximum penalty of one year in prison and a $100,000 fine.

Hill said little in court and left without making a statement. Her sentencing date was set for Nov. 27.

Hill was released on $150,000 bail that U.S. District Judge Michael Shipp said included being allowed to leave the country for music tours and a condition she must undergo mental health counseling. Her lawyer Nathan Hochman said Hill has been in family counseling for the past ten years.
