Soul icon Stevie Wonder and R&B singer Alicia Keys sent letters of support for Lauryn Hill to the judge overseeing her tax evasion case in a desperate bid to keep her out of jail.

The former Fugees star reached out to friends and family to write to the New Jersey judge on her behalf in a bid to land a lesser sentence after pleading guilty to three charges of failing to file tax returns between 2005 and 2007, with each count carrying a year behind bars.

On Monday (06May13), she was sentenced to serve three months in jail as punishment, and now Hill has penned a note of thanks to everyone who showed their support throughout her legal battle.

In the open letter, posted on her page, Hill writes, "I want to extend a sincere thank you to the following people, who wrote letters to the judge on my behalf", before listing the names of all of her pals, including Wonder and Keys.

She continued, "I also want to thank all of my family, friends, business associates, and fans who have called, emailed, sent texts, and posted messages of concern, encouragement, and support. I appreciate the well wishes, and I thank you for your prayers."

Hill must report to prison by 8 July (13).
