Marley told TMZ, “I will be there for my kids.”
The pair’s children range from age 5 to 15.
Marley also said while he’s always been active in his children’s lives, he will put forth an extra effort while Hill serves out her prison sentence.
“I will be there even more while she is dealing with this … to make sure that everything is fine,” he told TMZ.
Hill, a South Orange resident, was sentenced last Monday to three months in jail for tax evasion.
On the eve of her sentencing she paid the more than $970,000 in back taxes and fines she owed.
Marley, 40, and Hill, 37, met in 1996.
They dated for 13 years but never married. Their relationship ended in 2009.
Hill recorded songs about two of her children with Marley, “To Zion” on her first solo effort, 1998’s “The Miseducation of Lauryn Hill” and “Selah” from the 2002 “Divine Secrets of the Ya-Ya Sisterhood” soundtrack.
Marley was most recently linked to Brazilian model Isabeli Fontana. He was engaged to her until their September 2012 break-up.
Over the weekend, Hill thanked her supporters via her Tumblr blog.
The music maven must turn herself in by July 8. Until then, she is free to perform as she will in a concert Tuesday, May 14 at the Music Hall of Williamsburg in Brooklyn.
