Williams, 49, preyed on the girls, luring them into prostitution by making them think he loved them, Senior U.S. District Judge Daniel T.K. Hurley said Tuesday at the sentencing.
The girls were between the ages of 12 and 16 when they worked as prostitutes for Williams between August 2011 and May 2012, the South Florida Sun Sentinel reported Wednesday.
Williams is appealing his October convictions, insisting the girls lied in testimony. He claims he was a father figure attempting to help troubled girls, the newspaper said.
A jury convicted Williams of sex trafficking of minors and attempted sex trafficking of a minor.
