JoJo

At 13, the biggest milestone most kids hit is being allowed to roam the mall without parental supervision. But pint-size pop starlet JoJo celebrated her entry into her teens by becoming the youngest artist to ever reach No. 1 on the Billboard Top 40 chart, thanks to the breakout success of her 2004 banger “Leave (Get Out).” When the throaty young singer went silent after her 2006 sophomore effort, many fans grew concerned, only to learn she was embroiled in a years-long legal feud with her label. Newly emancipated, JoJo is officially back with Mad Love, her first album in 10 years, which finds her all grown up and better than ever. 18+.
